By default holes and pads will be cleared by an amount given in the corresponding footprint file. The 2011 version of PCB still won't allow you to place vias so close that their holes overlap. See You need a pcb that was compiled from source later than June 2010 to open these layouts. However, the open source application qcad can open DXF files and export them as postscript. The Master document for footprint creation is the PCB Manual. User Manual for PCB-v4.1.1-g8ab2fac2 an open source, interactive printed circuit board layout program by Harry Eaton and PCB Contributors library have very small pads which will be too weak if used for single sided board. Connect the polygon that will become your power planes to a net and the autorouter will figure it all out. Auto-pan can be toggled during move with a right mouse button click. Alternatively you can Create a “jumper” symbol in the schematic and put that The first software was released on 1 April 1998, and included a schematic capture program and a netlister. The image can be in jpg, png, or ppm format. stick to that layer. You can make them pop into your eye by setting the rat thickness to some big value e.g. You can tell, whether the screen will auto-pan by looking for little squares at the end of the cross hair cursor. When building the rat nests pcb is will look for nets to U2 that, of course don't exist. 3. gEDA provides gerber file viewer. Settings in this file will overwrite the system configuration. If the pads surrounding the mounting hole need to be electrically connected then you should show the connection in your schematic. The tab “Aperture usage” gives the number of SMD pads. (Note, this setting is currently broken). You may need some trick polygon clearances to get power routing and routing within a board outline. The pcb manual contains a concise description of the user interface in the "pad_1" or "positive" or any other string. For more info, see Freescale App-Note AN4005. How do I rotate objects by an arbitrary angle? Lower case letters at the end of a refdes are ignored. Of course, if you accidentally have a net touching the polygon, all routes will get shorted to that net. You can copy groups of tracks and vias. Sometimes this clearance might not be what your design needs. DRC enforcement uses the ratsnest to determine where a track is allowed to go. To do this: The absolute origin is always in the upper left corner of the accessible area. If you put an unknown token in the layer-stack string, pcb responds with a list of known layer names. Note, that the lock tool always toggles the lock state of the object you click at. The mouse is only sensitive to components on the active side of the board. Else, the line in settings will be ignored. drill diameters, trace width/space specs)? the plated-holes one to unplated-holes. How do I move objects by an arbitrary distance? Use rectangles and polygon planes. If a `.pcb' file exists, it is searched for elements with a non-empty element name with no matching schematic symbol. The code base is a departure from the original PCB in that a complete Tcl command-line API was concocted for PCB, and the GUI At least put a version number on it, so if you have to rev the board, you can tell the good from the bad. Just put a normal thermal relief on the via and then shift click on it to cycle through to the one with no relief. These elements are removed from the `.pcb' file, with a backup in a `.pcb.bak' file. General Guidelines for Releases. If there is no sign, it is interpreted as an absolute value. You can move and delete vertices and you can insert vertices using two techniques. KiCad . Draw a rectangle to comfortably surround the vias. Every track will become a pad. If not specified the units will default to the internal unit of 0.01 mil. This means, you can adjust the clearance individually: Make sure, the soldermask layer is not active. KiCad now has a push and shove router which is capable of routing differential pairs and interactively tuning trace lengths. Check, what it needs to reproduce the bug. 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”). http://www.luciani.org/geda/pcb/faq-pcb-footprint.html, http://www.luciani.org/geda/pcb/pcb-footprint-list.html#Hardware, http://wiki.geda-project.org/geda:mailinglists, CC Attribution-Share Alike 4.0 International. Do Auto-route all rats. You may want to set the marker to a grid point or a specific pin. Flip the board again to return to default view. On how to install a current version of pcb, see above. )), 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. “78740000” (about 78-3/4“). You can generate boards of any shape this way. How come? So you can immediately go on routing and find a better way. The best way to check for redundant polygons is to edit the source of your layout with an ascii editor. Both should now be marked with the “found” color and should be connectable. Gerüstbau nur mit einem Baulift aus dem Hause GEDA. costs by editing the autoroute.c source file and changing the directional costs in lines 929-940 and try again. In pcb vias are covered by soldermask by default. Verify that no soldermask or silkscreen overlays a copper pad or through-hole. So install of a more current version might help. How do I import external vector graphics? One way to get there perfectly, is to lay a ground plane into the layout. First select the objects you want to manipulate. Pcb-rnd is used professionally as well as in universities. How do I move one set of layer tracks to a different layer? End with upper case or a digit; the lowercase letters are simply ignored. How do I put components on both faces in PCB? the section Vendor-drill-mapping in the pcb manual for the syntax of this file. Why is it possible to make a thermal for pin, but not for a pad? The pads I've painstakingly created the SetFlag description in the pcb manual for more details on these commands. Type : to get the command line window, then type: where is a size given in 1/100 of a mil. 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. Click and drag a new point into the polygon. The gEDA project was started by Ales Hvezda in an effort to remedy the lack of free software EDA tools for Linux/UNIX. gEDA PCB . Just unselect the layers you don’t want (usually green and blue) by clicking on the name of the layer, then press autoroute. A prefixed sign means increment, or decrement. i didn't find anything about > > this in my first read of the PCB doc. Else the object is moved to absolute coordinates. Or you can add a layer from scratch (File → Preferences… → Layers → Add) and rename it accordingly. Add a symbol for the mounting hole and change its footprint attribute. It turns the solder layer on top, and component layer on bottom. A settings file for a4 paper, no alignment marks, multi page output would contain: There is no GUI way to modify the mouse behavior. The annular ring is the distance between the hole’s edge and the outer diameter of the metallization. How do I temporarily change keyboard shortcuts? %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. select all objects on active layers. This information should be available from your PCB fabrication house; ask them for their manufacturing rules document. Export as eps if you can and make sure that your logo fits into the bounding box (check with a postscript viewer such as ggv). Use the Preferences… dialog to make sure, this layer is not in the same group as the tracks. Some board houses ask for the number of SMD pads to help them with their quote. KiCad includes a 3D viewer which you can use to inspect your design in an interactive canvas. To connect the two segments, here are some suggestions: This is a known weakness of the Auto-enforce-DRC mode. The keyboard shortcut to this action is Shift+J. To delete a vertex, a corner in your polygon, put your crosshairs over the point and hit Delete on the keyboard. Thus, the components U2foo and U2bar both look like U2 to pcb. You didn't answer my question. Insert desired footprint 3. 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. Activate the solder mask layer. You can have the autorouter work only within a given area by drawing a copper polygon conforming to your board’s boundary and placing it in each layer you’re trying to autoroute. If you want to set or clear the join flag rather than toggle it, you can use If you try to insert new vertices into a polygon that don’t fall onto lines of proper 45 and 90 degree constraints, PCB disallows the action!). How should I check my design? ), physical layer how-to (outline, direct (x,y) footprint placement, part insertion). The layout produced by the autorouter is ugly! You can put this list in a “vendor resource file”. Lower case letters are meant to differentiate slots of a multi-component. History. E.g. How do I place vias that connect to a polygon for full thermal dissipation or full shielding integrity? Turn off via visibility if you don't want it to introduce any new vias. gEDA/pcb -> G-code. You have to give the option “--as-shown”. If this does not apply, see above for possible measures to ameliorate the situation. Alternatively a restart will recalculate the polygons too. See the page http://www.delorie.com/pcb/bg-image.html at DJ Delorie's PCB HID website. 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. Unfortunately, there is no way to save the layout in a way that allows older versions of pcb to read the file. 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] Use a footprint for the mounting hole or place a via. Pcb is a handy tool for laying out printed circuit boards. It's all just names when you're doing single sided. For arbitrary angles, press the period key ., or choose 'All-direction' lines in the Setting menu. It does not interfere with the file name. 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. Parts of the polygon that are not connected to some net are automatically eliminated. tracks: Set the join flag of the track. How do I set the default values of the postscript dialog? 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). These config files define user global settings when you put them in %USERPROFILE%\.gEDA … 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'. 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). Besides running the DRC checker, it is essential to check your Gerber files. You can achieve open vias by setting their clearance value to a proper value. If you need to make several such thermals, spend a little time making the first one just the way you want then copy the fingers to the buffer and paste it where you want the others. The sets bear suggestive names (Signal, Power, Fat and Skinny). In pcb, the polygon itself has no built-in clearance. Load this file to pcb. Take a single line segment and move the end-point on top of the start-point. Type pcb --help for a list of available options. (its path may vary on various systems). The layout script pcb-matrix arranges multiple copies of a sample layout in a matrix way. Is there a way to do multiple instances of a subcircuits? A prefixed = sets the clearance to the following value. John Luciani wrote a pair of perl scripts that can do better than that. Import of external vector graphics is useful if an irregular shape of the pcb is required. PCB includes a rats nest feature and schematic/netlist import, design rule checking, and can provide industry standard RS-274X (Gerber), NC drill, and centroid data (X-Y data) output for use in the board fabrication and assembly process, as well as photorealistic and design review images. Licenses: GPL Version: 1:4.2.0-1 website. Yes, the layer might get displayed; not a problem as you’ve already selected the tracks you want. Make at least one connection from any plane you want the router to use to the net you want it to connect to. Look into the source of your layout to find and delete unnecessary polygons. Add the Shift modifier to decrease the clearance. I can select the existing area. Turn on the soldermask layer. 1mm = 3937. You can do this with the, pads: Currently, there is no way to directly connect a polygon to a pad. In pcb the Delete button does not act on the selection, but on the object currently under the mouse. PCB won't let me connect to copper that is not connected to anything! Deactivated layers are ignored. Why text I add to the solder side not reversed? Disable any nets that you don't want the autorouter to route – double-click them in the netlist window to add/remove the “*”. Polygons can be edited equally well in “thin line draw” mode (Settings → Thin draw poly) or in normal mode. If you use the GTK-HID double-click a route to disable it. Now change the active layer to your desired routing layer. Select the layer the polygon sits on. Just selecting the solder side is insufficient. The layout produced by the autorouter is inefficient! Place this object centered on your via to connect it to a polygon. Close all instances of pcb and look for the line that starts with rat-thickness. It was not intended as a professional layout system, but as a tool which supports people who do some home-developing of hardware. In this case, it is possible that your track width violates the clearance requirements of the pin field. Most fabs will cut the board at the center of the lines. The above only applies to one object at a time. On load, pcb will substitute drill sizes so that the layout conforms to the list. Colors can be set in $HOME/.pcb/settings. Call PCB like this: The image will be scaled to the size of the canvas. After I defined those ground planes, pcb takes ages to load. Here are some things to check/verify: It limits the size of the image to NxN pixels, but maintains the aspect ratio. the shortcut will be working immediately. Make professional PCB layouts with up to 32 copper layers. There are a number of ways to change the size of already laid down tracks: A “thermal via” is not a via with a thermal relief. It will remove the last segment but keep the line tool attached to the mouse. you're looking at. Another trick is to make a zero-length line. Press K to increase the clearance of the object under the cursor. Rat thickness is set in $HOME/.pcb/preferences. Note, that the name of this layer is case sensitive. In default view the silk layer button refers to silkscreen on the component side of the board. Es besteht unter anderem aus dem Schaltplaneditor Gschem und dem Platinenlayoutprogramm PCB. To: gEDA bug mailing list Subject: Re: gEDA-bug: PCB :command lockup; From: Peter Lewis Date: Fri, 1 Jan 2010 08:50:28 +0000; Delivered-to: archiver@xxxxxxxx; Delivered-to: geda-bug@xxxxxxxxxxxxxx; Delivery-date: Fri, 01 Jan 2010 03:54:57 -0500; In-reply-to: <200912221054.00955.lewisp@xxxxxxxxxx> Use only plain rectangles for power/ground planes that you want the router to use. 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. Some fabs provide lists of standard drill sizes and charge extra if the design How do I drive a via to connect a track to a ground plane on a different layer? 2.1 Wichtige Einstellungen & Tips; 2.2 Autorouter; 2.3 Footprints; 3 Siehe auch; Gschem. Draw a track in the middle of the desired no solder mask area. Default keyboard shortcuts are defined in files called gpcb-menu.res if you use the default GTK interface. (If the rat visibility bothers you, you can hide the rats layer – but the rats must exist). The base Metric unit is 1nm (one nanometer). Older versions of pcb refuse to load a layout saved by a newer pcb binary. You may have to zoom out to get it on the screen. Bei GEDA erhalten Sie zudem Modelle für Gerüstaufzüge, Lastenaufzüge, Zahnstangenaufzüge und Seilaufzüge. 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. Pre-built packages are available on multiple operating systems. New text always reads correctly from the side deletes connected copper under the cursor. How do I make autorouter leave particular nets alone? If there is no eps export available, you can produce postscript by printing to a file. 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. How-to edit pcb-rnd and geda pcb footprints (same process) How to Edit gEDA PCB Footprint 1. Then, mouse over the rectangle and hit. Learn more. Moving a vertex is easily accomplished by un-selecting your polygon and then clicking and dragging that vertex to a new location. This marker is set to the current position of the mouse by the key sequence Ctrl+M. How do I change the soldermask clearance around a hole/pad? How do I force the autorouter to route only within my pcb outline? You’ll un-set the “clear pins/vias” flag and the vias will be connected to the larger polygon underneath. A variation on this technique is 1) click to select, followed by 2) click to place new vertex. For permanent change of keyboard shortcuts you can copy the system file to $HOME/.pcb/gpcb-menu.res and edit to your needs. If you use My preference is to create PCB footprints for the various types of mounting hardware. A via will be placed automatically at the endpoint of the last complete segment. Note: Square pads may not clear polygons correctly. “Buffer” → “Copy Selection To Buffer” seems to succeed (no complaints). Pads are the only carriers of netnames in pcb. What I can do about it? Then act on the selection: You may rip off the sub menu at the dashed line to make it stay on the screen for convenient repeated application. Voila! Else pcb won't let you connect the footprints with the copied tracks and vias. The auto pan feature was removed in September 2011. How do I route power and ground planes with the autorouter? This is like physically turning the board to the other side. This will be the case if a via is missing for some reason. Rectangular pads are ok, though. There is a complementary setting “Lock Names”, too. flip object to the other side of the board, open pinout window for element under mouse cursor, highlight connections to object under mouse cursor. You can switch to 45° mode with the slash key /. Temporarily hide the polygons. It is gridless and uses geometric rectangles only. The colors are saved to $HOME/.pcb/preferences on shut down of the application. This tutorial is functional and intended to generate results as quickly as possible. This should remove the silk of all far side components from the view. I usually use layer 8 for outlines: PCB will produce a gerber file called $NAME.outline.gbr that exclusively contains the objects in the outline layer. increased. What can I do about it? Shift-Click on the via to circle through the available styles of the connection. Allowable metric value range: “0.000001mm” to “2000mm”, imperial and metric may be mixed within a footprint (! Furthermore, you can use the background image as tool for making board revisions or redesigns. (see above). gEDA PCB. Rather, it's a via with no thermal relief punched into polygons on both sides of the board. Can I overlay a bitmap in the background? Bottom line: Don't use lower case letters at the end of a refdes, unless you know what you are doing. What gives!?!?!? Recent versions of gEDA (August 2010 or later) come with an G-code exporter. Installation. Start by clicking the edge you want to split with a new point. Yes. 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. With Lesstif-HID there is no preference dialog. pcb-rnd is a modular and compact (core under 60k SLOC, plugins at 100k SLOC) software application used for layout design of electrical circuits. However, coordinates of objects can also be given relative to the current grid. Note that you must subscribe to the geda-user e-mail list before you can post to the list. 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. Enter changejoin(selected) in the command window to toggle this flag for all tracks that are currently selected. The key-accels Tab, Shift+Tab, Ctrl+Tab and Ctrl+Shift+Tab will do the trick. How do I route a connection from solder to component side and back? There are two ways to connect to unconnected copper, anyway: Obviously, you can temporarily deactivate Auto enforce DRC clearance in the Settings menu. Why? The GUI provides no way to do similar subcircuits automatically. The same happens to components and their silk screen. 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. I try to move an object, but pcb won't let me! Translations of this page are also available in the following languages: Français, Русский. If SIZE is Lines don't have to be straight. Sometimes remaining rats are hard to see, because they have zero length. However, you can delete the current selection with the Backspace key. PCB Projects lists some wish-list items. start the line from somewhere else. Created a SOIC8 to DIP0830 breakout board with gEDA gschem and pcb for testing operational amplifiers like the Intersil CA3140MZ on a bread board ;-) Arcs, polygons and text in the outline layer also enter the gerber file. How do I achieve open vias clear of soldermask. There is no import filter to directly load a DXF file to pcb. It’s also possible to edit the native .pcb file format of your layout. Put the polygons (and rectangles) on a separate layer. 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). You can use the command setvalue(grid,value,unit). How-to edit pcb-rnd and geda pcb footprints - Duration: 1:45. celem1 441 views. How do I know, which side a component sits on? PCB Layout. and in the PCB Manual (pcb.pdf or pcb.html) Locked footprints are shown with a little L at their diamond shaped insertion mark. Have you tried the various clean-up tools under Connects → Optimize routed tracks? /usr/local/share or /usr/share/. In the GTK2 version of pcb coordinates are shown in the upper right corner of the main window. Except where otherwise noted, content on this wiki is licensed under the following license: Where can I read about the basics of using pcb? Everything turns pretty blue. These accels combine the swap with different vertical and horizontal flips. Set the current routing style for any nets not having a defined route style in the netlist. How do I permanently change keyboard shortcuts? will be greyed out. Because of this you must manually draw the thermal “fingers” to connect the pad to the ground plane. It is included in most major Linux distributions. deactivate all layers you don't want to print, open the file $NAME.frontpaste.gbr with gerbv. (Use the rectangle tool rather than the polygon tool!). Click anywhere on the board and the selection is pasted on the design again. Bauaufzüge für den reinen Materialtransport wie die Modelle GEDA 200 Z, 300 Z oder 500 Z decken Tragfähigkeiten bis 500 Kilogramm ab und sind der ideale Partner für den Gerüstbau. This also works with SelectedPins, SelectedPads, SelectedLines, SelectedArcs or even SelectedObjects. Optimize the rats with key O. Contribution of bug reports and/or patches are welcome. This is a technological limitation of the current auto router. This is a quick recap of a basic board build (schematic already done). This annulus is four arc segments. After you are finished with the changes, use the Preferences… dialog to let the polygon layer join the layer of the tracks. Therefore, turn on the silk Example for such a setting: Be sure, to remove any route-style line in ~/.pcb/preferences . Here's a File:GEDA-pcb-milling-patchset.zip you can apply before building pcb from source. However, you have to place the footprints manually. Afterward, an object report pops up that contains the lock state in the last line. A bug fix is when PCB doesn't do what it's supposed to do - this includes documentation bugs as well as code problems. In the netlist window, doubleclick on the specific rat name, then press O on your board window. I have a variety of silkscreens for various hardware combinations (hex nut, hex nut with washer, etc.) Design for two-sided, but with all the traces on the solder side. These polygons won't display because they shade each other. How do I trace a drawing, a print, or another PCB? In GTK-HID there is a Preferences… dialog in the File menu. Tcl/Tk interpreter. The lesstif interface reads pcb-menu.res files instead. Tracks are also avoided, if they have the clear polygons flag set (menu: Settings → New lines, arcs clear polygons). When you set your PCB size in PCB, you'll want to add the margin area. The gEDA Suite includes the program “gerbv” for this task. As workaround use two or more polygons that add to give a square. Is it possible to use an arbitrary grid spacing? You may switch off all the other layers to conveniently collect exclusively the vias. Run a check of design rules either through the command interface (“DRC()”) or from the menu (. Open up the netlist window. Since version 20070208 of pcb the resulting polygon will be one contiguous piece. On how to proceed further with that, see the PCB Milling page. If the value is preceded by a minus “-” or a plus “+” the clearance will be decreased or increased. When checked, the selection tool will exclusively act on text. hover the mouse cursor over the unconnected copper. From the command line: Add “solderside” to the layer-stack string of the print command. However, if don't use the holes in polygon features, you can just hand-edit the file version header back to 20070407 and open the file with the older pcb binary. Single sided boards do not have plated holes, so pad diameter for pins must be There is a set of predefined sizes for routing. This is useful with crammed layouts. To reverse: follow the same procedure. There's no such Place the via where you want it to live (left click to place). if you want a 10 mil clearance, put 2000 (20 mils) here, Move Absolute (x,y,mil) or Relative(+x,-y,mil), :ChangeClearSize(Selected,,). What can I do about it? of more than one item)? See the paragraph above for the details. The script sch-matrix places multiple copies of a basic block on the sheet. Open PCB 2.
