is a size given in 1/100 of a mil. So it is not necessarily a bug, but a price to be paid for a powerful feature. It’s easiest to do this if you shut off everything but that layer first (i.e. How do I force the autorouter to route only within my pcb outline? Except where otherwise noted, content on this wiki is licensed under the following license: Where can I read about the basics of using pcb? How do I hide the polygons while I edit the layout? Deactivate Auto enforce DRC clearance in the Settings menu during placement. How do I put components on both faces in PCB? … If you haven’t found an answer to your question about PCB on this page, or in the other documentation, then post to the list! The lesstif interface reads pcb-menu.res files instead. You may want to set the marker to a grid point or a specific pin. The current GTK snapshot (v20060288) defaults to “_/” but can be temporarily turned to “\_” with the Shift key. You can change the clearance on the fly for individual holes and pads just like vias. Sometimes this clearance might not be what your design needs. How should I check my design? Turn on the soldermask layer. How-to edit pcb-rnd and geda pcb footprints - Duration: 1:45. celem1 441 views. For more info, see Freescale App-Note AN4005. Use gimp, or any other image manipulation program to make the image look hazy so it does not interfere too much with the actual layout colors. The graphics will sit somewhere on the lower left of the view port. chosen, or rounded up to the next size in the list. (If the rat visibility bothers you, you can hide the rats layer – but the rats must exist). Rat thickness is set in $HOME/.pcb/preferences. select the all the vias you want to clear from soldermask. The universal undo key U works even while in the middle of track layout actions. This is a technological limitation of the current auto router. In December 2010 this overly cautious behavior was fixed. See the paragraph above for the details. I prefer to place all “production-ready” footprints in a single directory that is not in the gEDA/PCB install tree. Thus, you must have the ratsnest drawn in order to make connections in auto-DRC mode. How do I place vias that connect to a polygon for full thermal dissipation or full shielding integrity? (Can a polygon be made bare-copper with no solder mask?). Can PCB be used to make single layer boards? Recent versions of gEDA (August 2010 or later) come with an G-code exporter. For permanent change of keyboard shortcuts you can copy the system file to $HOME/.pcb/gpcb-menu.res and edit to your needs. Check that all hole diameters are called out at the correct size. Polygons can be edited equally well in “thin line draw” mode (Settings → Thin draw poly) or in normal mode. To delete a vertex, a corner in your polygon, put your crosshairs over the point and hit Delete on the keyboard. Disable the layer by a click on the corresponding layer button in the main window. Although only one silk layer button is visible in the GUI, silkscreen for both sides is automatically configured. I like to make a 1.00000 inch margin around the board. This is a quick recap of a basic board build (schematic already done). There are different ways to adequately connect different types of objects to a polygon: You didn't have New lines, arcs clear polygons checked in the Settings menu when you layed down the tracks. It is included in most major Linux distributions. on start-up, pcb will read this localised copy. (Note, this setting is currently ignored). Don't press any mouse button. In the netlist window, doubleclick on the specific rat name, then press O on your board window. Temporarily hide the polygons. Contribution of bug reports and/or patches are welcome. Shift-Click on the via to circle through the available styles of the connection. These polygons won't display because they shade each other. The amount of the increment can be configured in the dialog File → Preferences… → Increments. How can I set the manufacturing rules to use (i.e. However, you have to place the footprints manually. %USERPROFILE%\.gEDA %USERPROFILE%\.pcb %USERPROFILE%\AppData\Local\gEDA\geda-user.conf Creating files gschemrc and gafrc allows you to customize gschem and gnetlist behavior with your own settings. Check, what it needs to reproduce the bug. Yes, you can tell pcb on the command line to do an export. For footprint examples see http://www.luciani.org/geda/pcb/pcb-footprint-list.html#Hardware. The sets bear suggestive names (Signal, Power, Fat and Skinny). For arbitrary angles, press the period key ., or choose 'All-direction' lines in the Setting menu. Note on disabled nets: If you will be manually routing these later not using planes, it is usually better to let the autorouter route them then rip them up yourself afterwards. No need to select the object. Thus, the components U2foo and U2bar both look like U2 to pcb. Substitute “drillfile” with the name of your file. If you want to remove all locks, you may consider to remove all instances of the string lock in the *.pcb file with your favorite ascii editor. Pre-built packages are available on multiple operating systems. Please file a patch of the changes you had to make to the. Do a visual sanity check of all layers. How come? )), increment clearance of selected objects (soldermask to copper edge), decrement clearance of selected objects (soldermask to copper edge), increment width of the line tool, adds to the settings of the current line style, move the object under the cursor to the current layer, move selected objects to the current working layer (see, set the origin to the current position of the mouse pointer, show object refdes / pin number at mouse pointer, Select the shortest unselected rat on the board, toggle the octagon flag of the object under the cursor, connect the first point of a polygon with the last, increment size of the object under the cursor, decrement size of the object under the cursor, increase the hole of the object under the cursor, decrease the hole of the object under the cursor, increase the diameter of new vias by 5 mil, decrease the diameter of new vias by 5 mil, increase the drill diameter of new vias by 5 mil, decrease the drill diameter of new vias by 5 mil, distance to any other copper on any layer, actual width of the mask centered on pad copper, e.g. Except where otherwise noted, content on this wiki is licensed under the following license: PCB Command Line Action Reference (abridged), Footprint Creation for the Open-Source Layout Program PCB, CC Attribution-Share Alike 4.0 International, terminate the current action, e.g. Disable any nets that you don't want the autorouter to route – double-click them in the netlist window to add/remove the “*”. section "Getting Started". on one side. However, you can delete the current selection with the Backspace key. Select the layer the polygon sits on. Try decreasing the pin-to-metal clearance, or use a narrower track width. Here are some links to available scripts: There is a third party open source utility called pstoedit that converts postscript data to pcb format. You can also use this trick to autoroute only with small areas. deletes connected copper under the cursor. Check that your antipads (clearance around holes/vias) are large enough. Most of the coding for PCB 3.0 was done at MultiGiG, Inc., Scotts Valley, California, by Tim Edwards, Paramesh Santanam, and (working from India, courtesy of SynApps, Inc.), Nishit Patel. (see above).

Note that you must subscribe to the geda-user e-mail list before you can post to the list. Parts of the polygon that are not connected to some net are automatically eliminated. Older versions of pcb refuse to load a layout saved by a newer pcb binary. However, it won't complain if you managed to work-around this restriction. Type pcb --help for a list of available options. Otherwise you will not be allowed to connect (or approach) any copper that is not already connected to your net. The other one is to use gEDA Manager, which is probably the simplest way. Else, a default layer stack file will be used. The best way to check for redundant polygons is to edit the source of your layout with an ascii editor. This marker is set to the current position of the mouse by the key sequence Ctrl+M. But they demand calculation resources. Sometimes this route-blocking behaviour can come about from an error in your netlist. The layer-stack string can contain a comma separated list of the layers used in the GUI. Note, that the lock tool always toggles the lock state of the object you click at. Sign it and date it. User Manual for PCB-v4.1.1-g8ab2fac2 an open source, interactive printed circuit board layout program by Harry Eaton and PCB Contributors You can put this list in a “vendor resource file”. You just draw the desired outline with the line tool or the arc too. Another trick is to make a zero-length line. Verify that no soldermask or silkscreen overlays a copper pad or through-hole. One of PCB's great features is that it uses an easily understood ASCII file format. This effectively removes dead copper. How come? In addition, there is a special action that acts only on objects with clearance below a given minimum: MinClearGap(Selected,,). The synopsis of the pcb command is: pcb [OPTION ...] [LAYOUT-FILE.pcb] to start the application in GUI mode, or pcb [-h | -V | --copyright] for a list of options, version, and copyright, or pcb -p [OPTION ...] [LAYOUT-FILE.pcb] to print a layout, or pcb -x HID [OPTION ...] [LAYOUT-FILE.pcb] to export. I want to draw a track between two segments on the same net, but PCB won't let me! If unsure, deactivate the far side with the “far side” button, at the bottom of the layer button row. Power-users may want to keep a small custom library of these parts by saving them as elements. What can I do about it? At least put a version number on it, so if you have to rev the board, you can tell the good from the bad. Why text I add to the solder side not reversed? gEDA roadmap has some PCB items. Else, the line in settings will be ignored. Tracks are also avoided, if they have the clear polygons flag set (menu: Settings → New lines, arcs clear polygons). The net of the pad automatically transfers to the polygon. There is no import filter to directly load a DXF file to pcb. Here are some things to check/verify: It limits the size of the image to NxN pixels, but maintains the aspect ratio. How can I get a light canvas? If not specified the units will default to the internal unit of 0.01 mil. Anything larger means PCB units (i.e. stick to that layer. Is there a way to do multiple instances of a subcircuits? Installing: pamac install pacman -S Removing: pamac remove pacman -R . 1 Gschem; 2 PCB. Then I go to paste the copied area… and all that moves are a couple To reverse: follow the same procedure. If the pads surrounding the mounting hole need to be electrically connected then you should show the connection in your schematic. For etching, you likely want to reduce the amount of etched copper to a minimum. Yes, the layer might get displayed; not a problem as you’ve already selected the tracks you want. tracks: Set the join flag of the track. (Note, this setting is currently broken). Make professional PCB layouts with up to 32 copper layers. aren't copied. Moving a vertex is easily accomplished by un-selecting your polygon and then clicking and dragging that vertex to a new location. Locked objects won't highlight. What other resources exist for PCB information? Use Ctrl+M to set the origin and read the distance of the mouse pointer relative to this point on the upper right of the pcb window. flip object to the other side of the board, open pinout window for element under mouse cursor, highlight connections to object under mouse cursor. If you are viewing one side of the board, place a component there and (with the cursor over it) press the, 45° plus vertical/horizontal (status line: “\_”), either vertical or 45° (status line: “45”). Now change the active layer to your desired routing layer. Tcl/Tk interpreter. When a new version of gEDA/PCB comes out I do not make any changes to project files or libraries. How can I print the bottom side of the board? Then, mouse over the rectangle and hit. Optimize the rats with key O. Use the command “MoveObject()” as described above. 1mm = 3937. The Master document for footprint creation is the PCB Manual. Auto-pan can be toggled during move with a right mouse button click. This will make the, Position the mouse above the via (mouse cursor will change in recent versions of pcb). the shortcut will be working immediately. The usual workaround is to work with pads. Milling. Polygons are not “assigned” to nets, they're connected to them. Start by clicking the edge you want to split with a new point. Deactivated layers are ignored. You’ll un-set the “clear pins/vias” flag and the vias will be connected to the larger polygon underneath. The pair of scripts was written a few years ago and is not used regularly. Be sure that you have the settings such that new lines connect to planes when you draw them. there is a valid connection: You can draw tracks on top layer similar to a two layer Put the polygons (and rectangles) on a separate layer. Lower case letters at the end of a refdes are ignored. DRC enforcement uses the ratsnest to determine where a track is allowed to go. Now set the current layer to be the new layer. This information should be available from your PCB fabrication house; they normally publish the minimum annular ring requirements in their manufacturing rules document. stop drawing tracks, enter insert point mode. Here are a few ways to do this: One way, you’ll make an object that’s almost just like a thermal in that it goes between your via and the polygon – the difference is that you’ll actually create an annulus to completely fill the space between the hole and polygon (which because it’s clearance is turned on, is not connected to the pin). You have to give the option “--as-shown”. You can tell, whether the screen will auto-pan by looking for little squares at the end of the cross hair cursor. This includes rats and objects on invisible layers, add connections to object under mouse cursor to the set of found objects, increment grid by configured imperial increment, decrement grid by configured imperial increment, increment grid by configured metric increment, decrement grid by configured metric increment, toggle the visibility of the refdes or value attached to the component under the cursor, toggle the visibility of the refdes or value attached to selected components, toggle plating of a via. Use a footprint for the mounting hole or place a via. As new features are added to the file format, older versions of pcb might choke on portions of the layout using the bright new features. Starting with gEDA 20030901, gsch2pcb is packaged with gEDA and doesn't need to be separately installed. Most likely you named them such that PCB believes they are one part. Let the mouse hover over the object to be moved. PCB Manufacturing. (Use the rectangle tool rather than the polygon tool!). On load, pcb will substitute drill sizes so that the layout conforms to the list. To do this, press. How do I change the soldermask clearance around a hole/pad? How do I change the size of a graphical object (such as text, silkscreen lines, etc)? Polygons are making the GUI sluggish. There is a complementary setting “Lock Names”, too. Can I overlay a bitmap in the background? Unless your layout is pretty complex, you most likely have redundant polygons defined. costs by editing the autoroute.c source file and changing the directional costs in lines 929-940 and try again. This file may also exceptions and specify if the nearest diameter should be It increments the numbers and positions of the symbols as needed. Else pcb won't let you connect the footprints with the copied tracks and vias. 100 means “1 mil”). John Luciani wrote a pair of perl scripts that can do better than that. Settings in this file will overwrite the system configuration. the section Vendor-drill-mapping in the pcb manual for the syntax of this file. residing in the doc/ directory of your PCB installation A variation on this technique is 1) click to select, followed by 2) click to place new vertex. Some objects like vias and tracks yield useful information in object reports. save as eps (uncheck “make bounding box around page”), edit to your needs (lines only, no polygons), add the same pin number to all the lines with search and replace, save as *.fp at a place where pcb is looking for footprint libraries.

How do I move objects by an arbitrary distance? of more than one item)? How do I route a connection from solder to component side and back? You can move and delete vertices and you can insert vertices using two techniques. Activate the solder mask layer. You can copy these four items to the buffer to create a “zero-clearance thermal tool”. While this is desirable for the actual board, it requires calculation of quite extensive algorithms. Voila! Installation. This means, you need to design some copper to connect the polygon with a pad. greater, usually two to three times the drill size. When building the rat nests pcb is will look for nets to U2 that, of course don't exist. Auto-pan bugs me. Installing geda-gaf will give you the schematic editor and attribute editor, which is available in the official repositories.It may also be necessary to install ttf-dejavu and ttf-liberation to get the correct font scaling.. These options can also be set in a file $HOME/.pcb/settings. the howto page by DJ Delorie for a screenshot of pcb with background image. It turns the solder layer on top, and component layer on bottom. Use rectangles and polygon planes. Still, there is a couple of things you can do to improve the situation: Polygon calculation is potentially an expensive operation in terms of processor cycles. By default holes and pads will be cleared by an amount given in the corresponding footprint file. To do this: The absolute origin is always in the upper left corner of the accessible area. place tiny vias and increase their size afterwards. Isolated snippets are removed. E.g. How do I permanently change keyboard shortcuts? With Lesstif-HID there is no preference dialog. How-to edit pcb-rnd and geda pcb footprints (same process) How to Edit gEDA PCB Footprint 1. I use gEDA pcb infrequently and forget the basic steps between uses. Afterward, an object report pops up that contains the lock state in the last line. Bottom line: Don't use lower case letters at the end of a refdes, unless you know what you are doing. basicly what i want is to invoke 'make' from PCB, and > > subsequentally reading in some files. To connect the two segments, here are some suggestions: This is a known weakness of the Auto-enforce-DRC mode. Bottom line: Just position the mouse over an object and press the Delete button. In this mode, the line tool will only allow you to connect to copper with the same net as the place where the track started. Unpack the set, then do git am < xxx.patch Originally, the project planned to also write a PCB layout program. Learn more. drill diameters, trace width/space specs)? This means, you can adjust the clearance individually: Make sure, the soldermask layer is not active. How do I import external vector graphics? A second way uses the fact that auto-DRC relies on the found flag: Unfortunately, older versions of PCB not only prevent you from placing overlapping vias but drop them on load. If this does not apply, see above for possible measures to ameliorate the situation. Pcb is a handy tool for laying out printed circuit boards.

What gives!?!?!? Nothing detailed, just does it look approximately like you think it should. You can set the names and the default values of these parameter sets in a config file ( ~/.pcb/settings for the GTK-HID, or ~/.Xdefaults for the Lesstif-HID ). How do I rotate a selection (i.e. The solder mask should keep clear of the tracks, Increase the clearance of the pads to match the desired bare copper area. How do I temporarily change keyboard shortcuts? You can set the names and the default values of these parameter sets in a config file ( ~/.pcb/settings for the GTK-HID, or ~/.Xdefaults for the Lesstif-HID). It was not intended as a professional layout system, but as a tool which supports people who do some home-developing of hardware. As workaround use two or more polygons that add to give a square. layout. A prefixed = sets the clearance to the following value. Currently, there is no way to directly make polygons clear solder mask. Turn off visibility of any layers you don't want the router using. See Johns website for the details and a download of the scripts. In pcb, the polygon itself has no built-in clearance. Our goal is to only connect some of the pins/vias to the polygon, but to connect them better than a thermal does. gEDA tools are suitable for use by students, educators, hobbyists, consultants, small businesses, and even in large corporations where an engineer might need to crank out a quick PC board (e.g. Set the GND plane layer as the active layer. Locked footprints are shown with a little L at their diamond shaped insertion mark. The drawback of this trick is that when you change via size, you’ll also have to modify the size of these filler parts. Click anywhere on the board and the selection is pasted on the design again. How do I measure distances and dimensions of components? go to the menu and let the mouse hover over the item to be configured. On how to proceed further with that, see the PCB Milling page. For example, if you set it to 400, a 6000×8000 mil board would yield a 300×400 image, but a 6000×4500 board yields a 400×300 image. pcb-rnd is a modular and compact (core under 60k SLOC, plugins at 100k SLOC) software application used for layout design of electrical circuits. A via will be placed automatically at the endpoint of the last complete segment. There is also Stuart Brorson’s Footprint Creation for the Open-Source Layout Program PCB. It is the tracks, pads and pins that bear this property. Insert desired footprint 3. What can I do about it? This prevents ambiguities with components placed on both, top and bottom. See the output of pcb --help for details. This cannot be set to some other place. 3D Viewer. in places where you need a jumper. This is useful with crammed layouts. What gives? Check, weather the issue is already in the, Finally, as with all open source projects, you may flex your programming muscles and try to squish the bug yourself. The annular ring must be large enough to accommodate drill location + layer registration + other manufacturing inaccuracy. The pads I've painstakingly created silk, pins, other layers, etc). It is gridless and uses geometric rectangles only. PCB is an interactive printed circuit board editor for Unix, Linux, Windows, and Mac systems. This also works with SelectedPins, SelectedPads, SelectedLines, SelectedArcs or even SelectedObjects. Also make sure your trace widths and metal-metal separations are above the minimum specified by your PCB vendor. hover the mouse cursor over the unconnected copper. it MUST be consistent with the definitions on the netlist.

Welcome to Unconventional Wisdom Radio. Where fact and emotion battle.
The status line on the bottom of the page tells, which mode is in effect: The way to access these modes differs among the GUI versions. In this case you may add a bounding box with ps2epsi. Yes. If both coordinates are prefixed with a “+”, or “-” the move is relative to the current position. You can enter your outline thru PCB’s GUI. Thus the number 3000 corresponds to 30 mil. Gerber files, prints and other I/O issues. Alternatively, you can use with the command :LoadVendor(drillfile). The base Imperial unit is the “centimil”, or 1/100 of a thousandth, or 1/100,000 inch, or 0.00001 inch. This tutorial is functional and intended to generate results as quickly as possible. How do I rotate objects by an arbitrary angle? Do Auto-route all rats. These vias get filled with solder to help create a large thermal mass to be used as a heat sink. Bei GEDA erhalten Sie zudem Modelle für Gerüstaufzüge, Lastenaufzüge, Zahnstangenaufzüge und Seilaufzüge. There is a special option to put a bitmap graphic in the background of the canvas. Hit. You can use gerbv to extract this pad count from your layout. It is also possible that you will experience this situation when drawing tracks between pins in a connector. Some fabs provide lists of standard drill sizes and charge extra if the design The parameter should be a number. Select the tracks. (its path may vary on various systems). Draw a rectangle to comfortably surround the vias. Else the object is moved to absolute coordinates. It's all just names when you're doing single sided. type whatever shortcut you'd like to assign to the item under the mouse. Of course, if you accidentally have a net touching the polygon, all routes will get shorted to that net. David Rowe has scripts for updating elements as well as adding/subtracting PCB files from each other on, Stuart Brorson wrote a simple script which generates footprints for two terminal SMT passives. Allowable metric value range: “0.000001mm” to “2000mm”, imperial and metric may be mixed within a footprint (! In general, there are three types of changes that go into PCB - bug fixes, new features, and incompatible changes. You can use your favorite vector graphics utility to produce a logo or any kind of fancy layout. Type : to get the command line window, then type: where is a size given in 1/100 of a mil. So it is not necessarily a bug, but a price to be paid for a powerful feature. It’s easiest to do this if you shut off everything but that layer first (i.e. How do I force the autorouter to route only within my pcb outline? Except where otherwise noted, content on this wiki is licensed under the following license: Where can I read about the basics of using pcb? How do I hide the polygons while I edit the layout? Deactivate Auto enforce DRC clearance in the Settings menu during placement. How do I put components on both faces in PCB? … If you haven’t found an answer to your question about PCB on this page, or in the other documentation, then post to the list! The lesstif interface reads pcb-menu.res files instead. You may want to set the marker to a grid point or a specific pin. The current GTK snapshot (v20060288) defaults to “_/” but can be temporarily turned to “\_” with the Shift key. You can change the clearance on the fly for individual holes and pads just like vias. Sometimes this clearance might not be what your design needs. How should I check my design? Turn on the soldermask layer. How-to edit pcb-rnd and geda pcb footprints - Duration: 1:45. celem1 441 views. For more info, see Freescale App-Note AN4005. Use gimp, or any other image manipulation program to make the image look hazy so it does not interfere too much with the actual layout colors. The graphics will sit somewhere on the lower left of the view port. chosen, or rounded up to the next size in the list. (If the rat visibility bothers you, you can hide the rats layer – but the rats must exist). Rat thickness is set in $HOME/.pcb/preferences. select the all the vias you want to clear from soldermask. The universal undo key U works even while in the middle of track layout actions. This is a technological limitation of the current auto router. In December 2010 this overly cautious behavior was fixed. See the paragraph above for the details. I prefer to place all “production-ready” footprints in a single directory that is not in the gEDA/PCB install tree. Thus, you must have the ratsnest drawn in order to make connections in auto-DRC mode. How do I place vias that connect to a polygon for full thermal dissipation or full shielding integrity? (Can a polygon be made bare-copper with no solder mask?). Can PCB be used to make single layer boards? Recent versions of gEDA (August 2010 or later) come with an G-code exporter. For permanent change of keyboard shortcuts you can copy the system file to $HOME/.pcb/gpcb-menu.res and edit to your needs. Check that all hole diameters are called out at the correct size. Polygons can be edited equally well in “thin line draw” mode (Settings → Thin draw poly) or in normal mode. To delete a vertex, a corner in your polygon, put your crosshairs over the point and hit Delete on the keyboard. Disable the layer by a click on the corresponding layer button in the main window. Although only one silk layer button is visible in the GUI, silkscreen for both sides is automatically configured. I like to make a 1.00000 inch margin around the board. This is a quick recap of a basic board build (schematic already done). There are different ways to adequately connect different types of objects to a polygon: You didn't have New lines, arcs clear polygons checked in the Settings menu when you layed down the tracks. It is included in most major Linux distributions. on start-up, pcb will read this localised copy. (Note, this setting is currently ignored). Don't press any mouse button. In the netlist window, doubleclick on the specific rat name, then press O on your board window. Temporarily hide the polygons. Contribution of bug reports and/or patches are welcome. Shift-Click on the via to circle through the available styles of the connection. These polygons won't display because they shade each other. The amount of the increment can be configured in the dialog File → Preferences… → Increments. How can I set the manufacturing rules to use (i.e. However, you have to place the footprints manually. %USERPROFILE%\.gEDA %USERPROFILE%\.pcb %USERPROFILE%\AppData\Local\gEDA\geda-user.conf Creating files gschemrc and gafrc allows you to customize gschem and gnetlist behavior with your own settings. Check, what it needs to reproduce the bug. Yes, you can tell pcb on the command line to do an export. For footprint examples see http://www.luciani.org/geda/pcb/pcb-footprint-list.html#Hardware. The sets bear suggestive names (Signal, Power, Fat and Skinny). For arbitrary angles, press the period key ., or choose 'All-direction' lines in the Setting menu. Note on disabled nets: If you will be manually routing these later not using planes, it is usually better to let the autorouter route them then rip them up yourself afterwards. No need to select the object. Thus, the components U2foo and U2bar both look like U2 to pcb. Substitute “drillfile” with the name of your file. If you want to remove all locks, you may consider to remove all instances of the string lock in the *.pcb file with your favorite ascii editor. Pre-built packages are available on multiple operating systems. Please file a patch of the changes you had to make to the. Do a visual sanity check of all layers. How come? )), increment clearance of selected objects (soldermask to copper edge), decrement clearance of selected objects (soldermask to copper edge), increment width of the line tool, adds to the settings of the current line style, move the object under the cursor to the current layer, move selected objects to the current working layer (see, set the origin to the current position of the mouse pointer, show object refdes / pin number at mouse pointer, Select the shortest unselected rat on the board, toggle the octagon flag of the object under the cursor, connect the first point of a polygon with the last, increment size of the object under the cursor, decrement size of the object under the cursor, increase the hole of the object under the cursor, decrease the hole of the object under the cursor, increase the diameter of new vias by 5 mil, decrease the diameter of new vias by 5 mil, increase the drill diameter of new vias by 5 mil, decrease the drill diameter of new vias by 5 mil, distance to any other copper on any layer, actual width of the mask centered on pad copper, e.g. Except where otherwise noted, content on this wiki is licensed under the following license: PCB Command Line Action Reference (abridged), Footprint Creation for the Open-Source Layout Program PCB, CC Attribution-Share Alike 4.0 International, terminate the current action, e.g. Disable any nets that you don't want the autorouter to route – double-click them in the netlist window to add/remove the “*”. section "Getting Started". on one side. However, you can delete the current selection with the Backspace key. Select the layer the polygon sits on. Try decreasing the pin-to-metal clearance, or use a narrower track width. Here are some links to available scripts: There is a third party open source utility called pstoedit that converts postscript data to pcb format. You can also use this trick to autoroute only with small areas. deletes connected copper under the cursor. Check that your antipads (clearance around holes/vias) are large enough. Most of the coding for PCB 3.0 was done at MultiGiG, Inc., Scotts Valley, California, by Tim Edwards, Paramesh Santanam, and (working from India, courtesy of SynApps, Inc.), Nishit Patel. (see above).

Note that you must subscribe to the geda-user e-mail list before you can post to the list. Parts of the polygon that are not connected to some net are automatically eliminated. Older versions of pcb refuse to load a layout saved by a newer pcb binary. However, it won't complain if you managed to work-around this restriction. Type pcb --help for a list of available options. Otherwise you will not be allowed to connect (or approach) any copper that is not already connected to your net. The other one is to use gEDA Manager, which is probably the simplest way. Else, a default layer stack file will be used. The best way to check for redundant polygons is to edit the source of your layout with an ascii editor. This marker is set to the current position of the mouse by the key sequence Ctrl+M. But they demand calculation resources. Sometimes this route-blocking behaviour can come about from an error in your netlist. The layer-stack string can contain a comma separated list of the layers used in the GUI. Note, that the lock tool always toggles the lock state of the object you click at. Sign it and date it. User Manual for PCB-v4.1.1-g8ab2fac2 an open source, interactive printed circuit board layout program by Harry Eaton and PCB Contributors You can put this list in a “vendor resource file”. You just draw the desired outline with the line tool or the arc too. Another trick is to make a zero-length line. Verify that no soldermask or silkscreen overlays a copper pad or through-hole. One of PCB's great features is that it uses an easily understood ASCII file format. This effectively removes dead copper. How come? In addition, there is a special action that acts only on objects with clearance below a given minimum: MinClearGap(Selected,,). The synopsis of the pcb command is: pcb [OPTION ...] [LAYOUT-FILE.pcb] to start the application in GUI mode, or pcb [-h | -V | --copyright] for a list of options, version, and copyright, or pcb -p [OPTION ...] [LAYOUT-FILE.pcb] to print a layout, or pcb -x HID [OPTION ...] [LAYOUT-FILE.pcb] to export. I want to draw a track between two segments on the same net, but PCB won't let me! If unsure, deactivate the far side with the “far side” button, at the bottom of the layer button row. Power-users may want to keep a small custom library of these parts by saving them as elements. What can I do about it? At least put a version number on it, so if you have to rev the board, you can tell the good from the bad. Why text I add to the solder side not reversed? gEDA roadmap has some PCB items. Else, the line in settings will be ignored. Tracks are also avoided, if they have the clear polygons flag set (menu: Settings → New lines, arcs clear polygons). The net of the pad automatically transfers to the polygon. There is no import filter to directly load a DXF file to pcb. Here are some things to check/verify: It limits the size of the image to NxN pixels, but maintains the aspect ratio. How can I get a light canvas? If not specified the units will default to the internal unit of 0.01 mil. Anything larger means PCB units (i.e. stick to that layer. Is there a way to do multiple instances of a subcircuits? Installing: pamac install pacman -S Removing: pamac remove pacman -R . 1 Gschem; 2 PCB. Then I go to paste the copied area… and all that moves are a couple To reverse: follow the same procedure. If the pads surrounding the mounting hole need to be electrically connected then you should show the connection in your schematic. For etching, you likely want to reduce the amount of etched copper to a minimum. Yes, the layer might get displayed; not a problem as you’ve already selected the tracks you want. tracks: Set the join flag of the track. (Note, this setting is currently broken). Make professional PCB layouts with up to 32 copper layers. aren't copied. Moving a vertex is easily accomplished by un-selecting your polygon and then clicking and dragging that vertex to a new location. Locked objects won't highlight. What other resources exist for PCB information? Use Ctrl+M to set the origin and read the distance of the mouse pointer relative to this point on the upper right of the pcb window. flip object to the other side of the board, open pinout window for element under mouse cursor, highlight connections to object under mouse cursor. If you are viewing one side of the board, place a component there and (with the cursor over it) press the, 45° plus vertical/horizontal (status line: “\_”), either vertical or 45° (status line: “45”). Now change the active layer to your desired routing layer. Tcl/Tk interpreter. When a new version of gEDA/PCB comes out I do not make any changes to project files or libraries. How can I print the bottom side of the board? Then, mouse over the rectangle and hit. Optimize the rats with key O. Use the command “MoveObject()” as described above. 1mm = 3937. The Master document for footprint creation is the PCB Manual. Auto-pan can be toggled during move with a right mouse button click. This will make the, Position the mouse above the via (mouse cursor will change in recent versions of pcb). the shortcut will be working immediately. The usual workaround is to work with pads. Milling. Polygons are not “assigned” to nets, they're connected to them. Start by clicking the edge you want to split with a new point. Deactivated layers are ignored. You’ll un-set the “clear pins/vias” flag and the vias will be connected to the larger polygon underneath. The pair of scripts was written a few years ago and is not used regularly. Be sure that you have the settings such that new lines connect to planes when you draw them. there is a valid connection: You can draw tracks on top layer similar to a two layer Put the polygons (and rectangles) on a separate layer. Lower case letters at the end of a refdes are ignored. DRC enforcement uses the ratsnest to determine where a track is allowed to go. Now set the current layer to be the new layer. This information should be available from your PCB fabrication house; they normally publish the minimum annular ring requirements in their manufacturing rules document. stop drawing tracks, enter insert point mode. Here are a few ways to do this: One way, you’ll make an object that’s almost just like a thermal in that it goes between your via and the polygon – the difference is that you’ll actually create an annulus to completely fill the space between the hole and polygon (which because it’s clearance is turned on, is not connected to the pin). You have to give the option “--as-shown”. You can tell, whether the screen will auto-pan by looking for little squares at the end of the cross hair cursor. This includes rats and objects on invisible layers, add connections to object under mouse cursor to the set of found objects, increment grid by configured imperial increment, decrement grid by configured imperial increment, increment grid by configured metric increment, decrement grid by configured metric increment, toggle the visibility of the refdes or value attached to the component under the cursor, toggle the visibility of the refdes or value attached to selected components, toggle plating of a via. Use a footprint for the mounting hole or place a via. As new features are added to the file format, older versions of pcb might choke on portions of the layout using the bright new features. Starting with gEDA 20030901, gsch2pcb is packaged with gEDA and doesn't need to be separately installed. Most likely you named them such that PCB believes they are one part. Let the mouse hover over the object to be moved. PCB Manufacturing. (Use the rectangle tool rather than the polygon tool!). On load, pcb will substitute drill sizes so that the layout conforms to the list. To do this, press. How do I change the soldermask clearance around a hole/pad? How do I change the size of a graphical object (such as text, silkscreen lines, etc)? Polygons are making the GUI sluggish. There is a complementary setting “Lock Names”, too. Can I overlay a bitmap in the background? Unless your layout is pretty complex, you most likely have redundant polygons defined. costs by editing the autoroute.c source file and changing the directional costs in lines 929-940 and try again. This file may also exceptions and specify if the nearest diameter should be It increments the numbers and positions of the symbols as needed. Else pcb won't let you connect the footprints with the copied tracks and vias. 100 means “1 mil”). John Luciani wrote a pair of perl scripts that can do better than that. Settings in this file will overwrite the system configuration. the section Vendor-drill-mapping in the pcb manual for the syntax of this file. residing in the doc/ directory of your PCB installation A variation on this technique is 1) click to select, followed by 2) click to place new vertex. Some objects like vias and tracks yield useful information in object reports. save as eps (uncheck “make bounding box around page”), edit to your needs (lines only, no polygons), add the same pin number to all the lines with search and replace, save as *.fp at a place where pcb is looking for footprint libraries.

How do I move objects by an arbitrary distance? of more than one item)? How do I route a connection from solder to component side and back? You can move and delete vertices and you can insert vertices using two techniques. Activate the solder mask layer. You can copy these four items to the buffer to create a “zero-clearance thermal tool”. While this is desirable for the actual board, it requires calculation of quite extensive algorithms. Voila! Installation. This means, you need to design some copper to connect the polygon with a pad. greater, usually two to three times the drill size. When building the rat nests pcb is will look for nets to U2 that, of course don't exist. Auto-pan bugs me. Installing geda-gaf will give you the schematic editor and attribute editor, which is available in the official repositories.It may also be necessary to install ttf-dejavu and ttf-liberation to get the correct font scaling.. These options can also be set in a file $HOME/.pcb/settings. the howto page by DJ Delorie for a screenshot of pcb with background image. It turns the solder layer on top, and component layer on bottom. Use rectangles and polygon planes. Still, there is a couple of things you can do to improve the situation: Polygon calculation is potentially an expensive operation in terms of processor cycles. By default holes and pads will be cleared by an amount given in the corresponding footprint file. To do this: The absolute origin is always in the upper left corner of the accessible area. place tiny vias and increase their size afterwards. Isolated snippets are removed. E.g. How do I permanently change keyboard shortcuts? With Lesstif-HID there is no preference dialog. How-to edit pcb-rnd and geda pcb footprints (same process) How to Edit gEDA PCB Footprint 1. I use gEDA pcb infrequently and forget the basic steps between uses. Afterward, an object report pops up that contains the lock state in the last line. Bottom line: Don't use lower case letters at the end of a refdes, unless you know what you are doing. basicly what i want is to invoke 'make' from PCB, and > > subsequentally reading in some files. To connect the two segments, here are some suggestions: This is a known weakness of the Auto-enforce-DRC mode. Bottom line: Just position the mouse over an object and press the Delete button. In this mode, the line tool will only allow you to connect to copper with the same net as the place where the track started. Unpack the set, then do git am < xxx.patch Originally, the project planned to also write a PCB layout program. Learn more. drill diameters, trace width/space specs)? This means, you can adjust the clearance individually: Make sure, the soldermask layer is not active. How do I import external vector graphics? A second way uses the fact that auto-DRC relies on the found flag: Unfortunately, older versions of PCB not only prevent you from placing overlapping vias but drop them on load. If this does not apply, see above for possible measures to ameliorate the situation. Pcb is a handy tool for laying out printed circuit boards.

What gives!?!?!? Nothing detailed, just does it look approximately like you think it should. You can set the names and the default values of these parameter sets in a config file ( ~/.pcb/settings for the GTK-HID, or ~/.Xdefaults for the Lesstif-HID ). How do I rotate a selection (i.e. The solder mask should keep clear of the tracks, Increase the clearance of the pads to match the desired bare copper area. How do I temporarily change keyboard shortcuts? You can set the names and the default values of these parameter sets in a config file ( ~/.pcb/settings for the GTK-HID, or ~/.Xdefaults for the Lesstif-HID). It was not intended as a professional layout system, but as a tool which supports people who do some home-developing of hardware. As workaround use two or more polygons that add to give a square. layout. A prefixed = sets the clearance to the following value. Currently, there is no way to directly make polygons clear solder mask. Turn off visibility of any layers you don't want the router using. See Johns website for the details and a download of the scripts. In pcb, the polygon itself has no built-in clearance. Our goal is to only connect some of the pins/vias to the polygon, but to connect them better than a thermal does. gEDA tools are suitable for use by students, educators, hobbyists, consultants, small businesses, and even in large corporations where an engineer might need to crank out a quick PC board (e.g. Set the GND plane layer as the active layer. Locked footprints are shown with a little L at their diamond shaped insertion mark. The drawback of this trick is that when you change via size, you’ll also have to modify the size of these filler parts. Click anywhere on the board and the selection is pasted on the design again. How do I measure distances and dimensions of components? go to the menu and let the mouse hover over the item to be configured. On how to proceed further with that, see the PCB Milling page. For example, if you set it to 400, a 6000×8000 mil board would yield a 300×400 image, but a 6000×4500 board yields a 400×300 image. pcb-rnd is a modular and compact (core under 60k SLOC, plugins at 100k SLOC) software application used for layout design of electrical circuits. A via will be placed automatically at the endpoint of the last complete segment. There is also Stuart Brorson’s Footprint Creation for the Open-Source Layout Program PCB. It is the tracks, pads and pins that bear this property. Insert desired footprint 3. What can I do about it? This prevents ambiguities with components placed on both, top and bottom. See the output of pcb --help for details. This cannot be set to some other place. 3D Viewer. in places where you need a jumper. This is useful with crammed layouts. What gives? Check, weather the issue is already in the, Finally, as with all open source projects, you may flex your programming muscles and try to squish the bug yourself. The annular ring must be large enough to accommodate drill location + layer registration + other manufacturing inaccuracy. The pads I've painstakingly created silk, pins, other layers, etc). It is gridless and uses geometric rectangles only. PCB is an interactive printed circuit board editor for Unix, Linux, Windows, and Mac systems. This also works with SelectedPins, SelectedPads, SelectedLines, SelectedArcs or even SelectedObjects. Also make sure your trace widths and metal-metal separations are above the minimum specified by your PCB vendor. hover the mouse cursor over the unconnected copper. it MUST be consistent with the definitions on the netlist.
