Can polygons be un-masked? Subject and goal for this code sprint is to triage pcb bug reports in the Launchpad bug tracker and if possible prepare and apply patches for bugs, or to work on new features for pcb. Now change the active layer to your desired routing layer. As workaround use two or more polygons that add to give a square. These polygons won't display because they shade each other. 1mm = 3937. To change a whole track press F to find all segments that are connected to the object under the cursor and apply the action select(connection). Disable the layer by a click on the corresponding layer button in the main window. The sets bear suggestive names (Signal, Power, Fat and Skinny). Note: For internal reasons, FreeRotateBuffer does not work with exact squares. Select the layer the polygon sits on. Have you tried the various clean-up tools under Connects → Optimize routed tracks? pins and vias: Choose the thermal tool (“THRM”). Hit the button “Route Style” to configure the sizes of the current set to your needs. Some footprints in the default The base Imperial unit is the “centimil”, or 1/100 of a thousandth, or 1/100,000 inch, or 0.00001 inch. Recent versions of gEDA (August 2010 or later) come with an G-code exporter. This is a two step process. Answer: If the silk layer is off, you can't copy elements through the paste The layer-stack string can contain a comma separated list of the layers used in the GUI. How-to edit pcb-rnd and geda pcb footprints (same process) How to Edit gEDA PCB Footprint 1. Thus the number 3000 corresponds to 30 mil. I don't like that old-style black background. For footprint examples see http://www.luciani.org/geda/pcb/pcb-footprint-list.html#Hardware. Type : to get the command line window, then type: where is a size given in 1/100 of a mil. The mouse is only sensitive to components on the active side of the board. Sign it and date it. Make at least one connection from any plane you want the router to use to the net you want it to connect to. What other resources exist for PCB information? of traces and some vias. Draw a rectangle to comfortably surround the vias. However, you have to place the footprints manually. This attribute is used for the export actions. Then I go to paste the copied area… and all that moves are a couple The net of the pad automatically transfers to the polygon. Anything larger means PCB units (i.e. Don't end refdes's with lower case letters - they're reserved for gates within devices. How do I import external vector graphics? If pad clearance is not compatible with the demands of your pcb-fab you may consider to make local copies of the footprint files and change the clearance accordingly. Else the following will apply to the soldermask rather than to the polygon. The layout produced by the autorouter is inefficient! This can be done individually for every object, or collectively for selections of objects. The image can be in jpg, png, or ppm format. Else, a default layer stack file will be used. Please feel free to join in at #pcb before, or after, the stated time frame, there is always chance of meeting one of the developers or fellow contributors. How do I make a board outline to go with my gerbers to the board maker? Objects on component silk layer select all objects on active layers. How do I set the default values of the postscript dialog? Single sided boards do not have plated holes, so pad diameter for pins must be Because of this you must manually draw the thermal “fingers” to connect the pad to the ground plane. If you use Tcl/Tk interpreter. 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. (Note, this setting is currently ignored). It has options for including or excluding nets from the ratlist. These elements are removed from the `.pcb' file, with a backup in a `.pcb.bak' file. What is the easiest way to create a "thermal via"? This is how: The GTK version of pcb includes a neat way to change shortcuts on the fly: This setting will be reset at the next session of pcb. Licenses: GPL Version: 1:4.2.0-1 website. If you want to apply an already loaded vendor resource file again, you can do Apply vendor drill mapping from the Connects menu. Advanced users may soon nd it necessary to use the command line for some parts of the design process. What gives!?!?!? and in the PCB Manual (pcb.pdf or pcb.html) You should also refresh the rats regularly when drawing. Unless your layout is pretty complex, you most likely have redundant polygons defined. (refcard.pdf) containing description of all PCB shortcuts gEDA PCB. read the parameters to use for new objects from the object below the cursor. Enter changejoin(selected) in the command window to toggle this flag for all tracks that are currently selected. 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. PCB is an interactive printed circuit board editor for Unix, Linux, Windows, and Mac systems. No need to select the object. To insert a vertex, you’ll use the insert tool (Insert keystroke). The annular ring must be large enough to accommodate drill location + layer registration + other manufacturing inaccuracy. For more info, see Freescale App-Note AN4005. basicly what i want is to invoke 'make' from PCB, and > > subsequentally reading in some files. Sometimes this route-blocking behaviour can come about from an error in your netlist. One way to get there perfectly, is to lay a ground plane into the layout. A gzipped tarball is available. Lines don't have to be straight. See the paragraph above for the details. To connect the two segments, here are some suggestions: This is a known weakness of the Auto-enforce-DRC mode. In default view the silk layer button refers to silkscreen on the component side of the board. Access the report of the object currently under the mouse pointer with Ctrl+R. 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. Unfortunately, there is no way to save the layout in a way that allows older versions of pcb to read the file. This is a great way to trace hand-drawn artwork or another PCB, say one you made in software with a proprietary format, which you'd now like to 'unlock'. It is included in most major Linux distributions. The first software was released on 1 April 1998, and included a schematic capture program and a netlister. You can enter your outline thru PCB’s GUI. What can I do about it? After I defined those ground planes, pcb takes ages to load. You can use gerbv to extract this pad count from your layout. I can't copy component pads in a layout. To prevent this kind of misbehavior, the pcb file contains a note on the minimum version string for the binary. drill diameters, trace width/space specs)? At that time, the gEDA Project website and mailing lists were also set up.. Pcb is a handy tool for laying out printed circuit boards. A pcb footprint file may contain any of the following commands: PCB handles metric and imperial units in the following way: Element [element_flags, description, pcb_name, value, mark_x, mark_y, text_x, text_y, text_direction, text_scale, text_flags], Pad[x1 y1 x2 y2 thickness clearance mask name pad_number flags], Pin[x y thickness clearance mask drillholedia name number flags]. End with upper case or a digit; the lowercase letters are simply ignored. To delete a vertex, a corner in your polygon, put your crosshairs over the point and hit Delete on the keyboard. User Manual for PCB-v4.1.1-g8ab2fac2 an open source, interactive printed circuit board layout program by Harry Eaton and PCB Contributors Therefore, turn on the silk How come? For permanent change of keyboard shortcuts you can copy the system file to $HOME/.pcb/gpcb-menu.res and edit to your needs. There is a set of predefined sizes for routing. How do I change the size of a graphical object (such as text, silkscreen lines, etc)? gEDA/pcb -> G-code. New text always reads correctly from the side Yes, the layer might get displayed; not a problem as you’ve already selected the tracks you want. This tutorial is functional and intended to generate results as quickly as possible. If there are newlib footprints in the PCB library that I want to use I copy them to the “production-ready” footprint directory. These vias get filled with solder to help create a large thermal mass to be used as a heat sink. Some fabs provide lists of standard drill sizes and charge extra if the design Most probably the object is locked. Also make sure your trace widths and metal-metal separations are above the minimum specified by your PCB vendor. How should I check my design? Installing: pamac install pacman -S Removing: pamac remove pacman -R . The tool pstoedit can turn this postscript file into a format readable by pcb (see above). It’s also handy to put these “parts” in one of your PCB buffers so they’re at your fingertips. the shortcut will be working immediately. tracks: Set the join flag of the track. How do I change the soldermask clearance around a hole/pad? This is a known issue caused by the difficulty to know the reference direction of a square pad. A via will be placed automatically at the endpoint of the last complete segment. chosen, or rounded up to the next size in the list. Put the polygons (and rectangles) on a separate layer. the commands SetFlag(selected, join) and ClrFlag(selected, join). Gerber files, prints and other I/O issues. Although only one silk layer button is visible in the GUI, silkscreen for both sides is automatically configured. In addition there are a number of tokens that are technically no layers like “pins”, or “invisible”. Screenshot. 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! stop drawing tracks, enter insert point mode. Optimize the rats with key O. The sets bear suggestive names (Signal, Power, Fat and Skinny). On zoom, PCB unit rats will scale accordingly. the SetFlag description in the pcb manual for more details on these commands. See How do I rotate a selection (i.e. you're looking at. A pcb footprint file may contain any of the following commands: Element [element_flags, description, pcb_name, value, mark_x, mark_y, text_x, text_y, text_direction, text_scale, text_flags] Pad [x1 y1 x2 y2 thickness clearance mask name pad_number flags] How do I temporarily change keyboard shortcuts? In general, there are three types of changes that go into PCB - bug fixes, new features, and incompatible changes. (Use the rectangle tool rather than the polygon tool!). The pcb manual contains a concise description of the user interface in the enforce dimensions of the jumpers this way if you care. On how to install a current version of pcb, see above. aren't copied. buffer. Afterward, an object report pops up that contains the lock state in the last line. When you set your PCB size in PCB, you'll want to add the margin area. How do I make autorouter leave particular nets alone? (see above). Temporarily hide the polygons. Just put a normal thermal relief on the via and then shift click on it to cycle through to the one with no relief. “Buffer” → “Copy Selection To Buffer” seems to succeed (no complaints). This is because PCB has a powerful 45/90 degree constraints system. This is a technological limitation of the current auto router. Yes, you can tell pcb on the command line to do an export. It will remove the last segment but keep the line tool attached to the mouse. 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. (NOTE: Inserting points into polygon will generally work ONLY with “all direction lines” enabled (Settings → 'All direction' lines). In the Netlist window an asterisk appears in from of the rat name. This will be the case if a via is missing for some reason. In the GTK2 version of pcb coordinates are shown in the upper right corner of the main window. If the prefix is “+”, the size is Check that your antipads (clearance around holes/vias) are large enough. the autorouter, turn off all but the bottom layer. Open up the netlist window. However, it can be useful to use a combination of both meth-ods, as the command line interface offers more exible options. Pre-built packages are available on multiple operating systems. You have to give the option “--as-shown”. You can switch to 45° mode with the slash key /. Shift-Click on the via to circle through the available styles of the connection. Colors can be set in $HOME/.pcb/settings. Open PCB 2. The line tool knows about different modes to deal with transversal connections. If you don't like to use PCB confined to the area of the board, i.e. You can manipulate the clearance of all selected objects with the action ChangeClearSize(Selected,,). all through-hole components you can mess with layer directional The colors are saved to $HOME/.pcb/preferences on shut down of the application. A prefixed = sets the clearance to the following value. 1 Gschem; 2 PCB. You can move and delete vertices and you can insert vertices using two techniques. Every track will become a pad.

You can use these scripts either as they are, or modify them to suit your own goals. Allowable metric value range: “0.000001mm” to “2000mm”, imperial and metric may be mixed within a footprint (! So it is not necessarily a bug, but a price to be paid for a powerful feature. A prefixed sign means increment, or decrement. How do I achieve open vias clear of soldermask. will be greyed out. Auto-pan can be toggled during move with a right mouse button click. You can swap the roles of the sides to make components on the far side accessible. PCB Layout. What gives? Place the via where you want it to live (left click to place). I try to move an object, but pcb won't let me! The lesstif interface reads pcb-menu.res files instead. 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. Use the lock tool to unlock the object in question. Be sure that you have the settings such that new lines connect to planes when you draw them. Then, mouse over the rectangle and hit. PCB won't let me connect to copper that is not connected to anything! E.g. Move to different layers (M key) as you see fit. Question: I want to copy a section of my existing layout to another spot. 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. Start by clicking the edge you want to split with a new point. A single sided board. Refer Check that all trace widths are the correct size. This means, you can adjust the clearance individually: Make sure, the soldermask layer is not active. DRC enforcement uses the ratsnest to determine where a track is allowed to go. How do I know, which side a component sits on? This annulus is four arc segments. gschem ist der Schaltplaneditor aus dem Open Source … This is likely to be a major pain, but you can If a `.pcb' file exists, it is searched for elements with a non-empty element name with no matching schematic symbol. To see, whether it indeed is, Select all connected objects from the Select menu. Look into the source of your layout to find and delete unnecessary polygons. See the page http://www.delorie.com/pcb/bg-image.html at DJ Delorie's PCB HID website. select the all the vias you want to clear from soldermask. Rats are considered a connection. Polygons are making the GUI sluggish. It increments the numbers and positions of the symbols as needed. 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). on start-up, pcb will read this localised copy. Note: Square pads may not clear polygons correctly. Translations of this page are also available in the following languages: Français, Русский. The same happens to components and their silk screen. If the value is preceded by a minus “-” or a plus “+” the clearance will be decreased or increased. Except where otherwise noted, content on this wiki is licensed under the following license: Where can I read about the basics of using pcb? 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. So you can immediately go on routing and find a better way. Bei GEDA erhalten Sie zudem Modelle für Gerüstaufzüge, Lastenaufzüge, Zahnstangenaufzüge und Seilaufzüge. (its path may vary on various systems). Alternatively a restart will recalculate the polygons too. PCB! Default keyboard shortcuts are defined in files called gpcb-menu.res if you use the default GTK interface. You can alter the increase/decrease quantum using the File → Preferences… → Increments menu. (see above). Else, the line in settings will be ignored. This will trigger PCB to render that layer as a positive layer. to the pcb manual for the syntax of the ChangeSize action. I like to make a 1.00000 inch margin around the board. You can achieve open vias by setting their clearance value to a proper value. You can place a localized copy in $HOME/.pcb/. Load this file to pcb. there is a valid connection: You can draw tracks on top layer similar to a two layer How do I place vias that connect to a polygon for full thermal dissipation or full shielding integrity? The right pair is the absolute position, while the left pair reflects the position relative to an arbitrary marker. The amount of the increment can be configured in the dialog File → Preferences… → Increments. On start-up pcb reads the configuration from a system path, e.g. Try decreasing the pin-to-metal clearance, or use a narrower track width. The command interface provides more control over the actual size of the clearance. 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 “*”. In this case you may add a bounding box with ps2epsi. Are all layers negative/positive as they should be? hover the mouse cursor over the unconnected copper. History. How do I put components on both faces in PCB? Tracks are also avoided, if they have the clear polygons flag set (menu: Settings → New lines, arcs clear polygons). Older versions of pcb refuse to load a layout saved by a newer pcb binary. You can generate boards of any shape this way. I have a variety of silkscreens for various hardware combinations (hex nut, hex nut with washer, etc.) Use the Preferences… dialog to make sure, this layer is not in the same group as the tracks. The best way to check for redundant polygons is to edit the source of your layout with an ascii editor. So install of a more current version might help. In the netlist window, doubleclick on the specific rat name, then press O on your board window. Gerüstbau nur mit einem Baulift aus dem Hause GEDA. Let the mouse hover over the object to be moved. Reply-to: gEDA user mailing list Sender : geda-user-bounces@xxxxxxxxxxxxxx Hi, Kai-Martin; On 9/15/09, Kai-Martin Knaak wrote: > I just skipped through the prolific list of pcb options. While the pad width is limited to 250 mil, clearance can be arbitrary. 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. You didn't answer my question. * These accels are available in PCB, GTK GUI in versions after August 2011. The drawback of this trick is that when you change via size, you’ll also have to modify the size of these filler parts. The layout script pcb-matrix arranges multiple copies of a sample layout in a matrix way. The graphics will sit somewhere on the lower left of the view port. When you dump your gerbers, delete the component side one and rename 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. How do I move objects by an arbitrary distance? 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. silk, pins, other layers, etc). PCB seems to munge my components names and complains that it can't find proper nets for the pins! The polygons are shorting my tracks! Isolated snippets are removed. increased. See Type pcb --help for a list of available options. How do I define a silkscreen layer for the other side of the board? A different reason for numb objects is “Only Names” in the settings menu. Now you have a “single point line” (a circle) with the diameter equal to the line thickness. If you draw to silk, lines will always go to the current top silk layer, which is solder now. Furthermore, you can use the background image as tool for making board revisions or redesigns. Weird, but that's how it works. You can put this list in a “vendor resource file”. )), 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. (If the rat visibility bothers you, you can hide the rats layer – but the rats must exist). There is no import filter to directly load a DXF file to pcb. 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). The mentioned times are an approximation. If you want to set or clear the join flag rather than toggle it, you can use Import of external vector graphics is useful if an irregular shape of the pcb is required. 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. The pair of scripts was written a few years ago and is not used regularly. The pads I've painstakingly created Check that metal annular rings around holes/vias are large enough. Some board houses ask for the number of SMD pads to help them with their quote. Is there a way to do multiple instances of a subcircuits? i didn't find anything about > > this in my first read of the PCB doc. You may need some trick polygon clearances to get power routing and routing within a board outline. To place text or lines on solder silk you have to flip the board with the Tab key (or Shift+Tab if you prefer a left-right flip). John Luciani wrote a pair of perl scripts that can do better than that. Es besteht unter anderem aus dem Schaltplaneditor Gschem und dem Platinenlayoutprogramm PCB. You can set the color of the rats in File → Preferences… → Colors → Main colors. Bottom line: Just position the mouse over an object and press the Delete button. Else the object is moved to absolute coordinates. Otherwise you will not be allowed to connect (or approach) any copper that is not already connected to your net. All the parameters set in the print dialog can be used in the command line too. the plated-holes one to unplated-holes. You can also add another polygon on-top of the polygon to which you want to connect you vias. 3. gEDA provides gerber file viewer. on one side. This is useful with crammed layouts. It's all just names when you're doing single sided. These files should be written in guile script. Insert desired footprint 3. You may have to zoom out to get it on the screen. Alternatively, you can use with the command :LoadVendor(drillfile). I can select the existing area. Call pstoedit with the option “-f pcb” to produce a valid pcb file that contains the graphics as tracks on layer 1. How do I move objects to an absolute location? There are four basic ways to edit polygon outlines. I'm done with my layout. There is currently no GUI way to set the rat width, but you can edit your $HOME/.pcb/preferences file manually. How do I hide the polygons while I edit the layout? The auto pan feature was removed in September 2011. Connect the polygon that will become your power planes to a net and the autorouter will figure it all out. Press K to increase the clearance of the object under the cursor. If both coordinates are prefixed with a “+”, or “-” the move is relative to the current position. Another trick is to make a zero-length line. gEDA can export PCBs to the Gerber and other file formats, of course. However, the open source application qcad can open DXF files and export them as postscript. 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. You are likely drawing tracks with auto-DRC on. However, coordinates of objects can also be given relative to the current grid. Everything turns pretty blue. It is gridless and uses geometric rectangles only. On how to proceed further with that, see the PCB Milling page. 100 means “1 mil”). Voila! The gEDA project was started by Ales Hvezda in an effort to remedy the lack of free software EDA tools for Linux/UNIX. Use the cut buffer to copy the shape to your actual design. Often it’s useful to have vias connect completely to a polygon (a field of copper) for heat transfer – the apparent problem is that PCB polygons have only a single “clear pins/vias” flag for the entire polygon (toggled by the S key). Thus, you must have the ratsnest drawn in order to make connections in auto-DRC mode.
