How do I permanently change keyboard shortcuts? Now you have a “single point line” (a circle) with the diameter equal to the line thickness. Make sure, you don't have redundant polygons defined, which multiply overlay the same area. I don't like that old-style black background. (refcard.pdf) containing description of all PCB shortcuts 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. A prefixed = sets the clearance to the following value. If not specified the units will default to the internal unit of 0.01 mil. This cannot be set to some other place. 1 Gschem; 2 PCB. This will trigger PCB to render that layer as a positive layer. Design for two-sided, but with all the traces on the solder side. How do I import external vector graphics? aren't copied. Note: Square pads may not clear polygons correctly. Make at least one connection from any plane you want the router to use to the net you want it to connect to. Auto-pan can be toggled during move with a right mouse button click. In default view the silk layer button refers to silkscreen on the component side of the board. How do I route a connection from solder to component side and back? The universal undo key U works even while in the middle of track layout actions. Es besteht unter anderem aus dem Schaltplaneditor Gschem und dem Platinenlayoutprogramm PCB. The polygons are shorting my tracks! prefixed by “-” the size is decreased. gEDA ist ein Open Source Programmpaket zum Zeichnen von Schaltplänen und zur Entwicklung von Platinen. John Luciani wrote a pair of perl scripts that can do better than that. The result is a matching pair of schematic and layout with a subcircuit repeated multiple times. The other one is to use gEDA Manager, which is probably the simplest way. Simple integers for will set the clearance to this value. Turn on the soldermask layer. Pcb-rnd is used professionally as well as in universities. To prevent this kind of misbehavior, the pcb file contains a note on the minimum version string for the binary. 1mm = 3937. My preference is to create PCB footprints for the various types of mounting hardware. You can switch to 45° mode with the slash key /. Turn off via visibility if you don't want it to introduce any new vias. Locked objects won't highlight. (NOTE: Inserting points into polygon will generally work ONLY with “all direction lines” enabled (Settings → 'All direction' lines). For etching, you likely want to reduce the amount of etched copper to a minimum. How do I rotate objects by an arbitrary angle? Sometimes remaining rats are hard to see, because they have zero length. How do I define a silkscreen layer for the other side of the board? Type : to get the command line window, then type: where is a size given in 1/100 of a mil. "pad_1" or "positive" or any other string. Pcb is a handy tool for laying out printed circuit boards. 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. the howto page by DJ Delorie for a screenshot of pcb with background image. If you use an older version of PCB, you can do this: Probably you try to delete a selected object. deletes connected copper under the cursor. Click anywhere on the board and the selection is pasted on the design again. How do I put components on both faces in PCB? Disable any nets that you don't want the autorouter to route – double-click them in the netlist window to add/remove the “*”. I'm done with my layout. How do I place vias that connect to a polygon for full thermal dissipation or full shielding integrity? Yes. Check that metal annular rings around holes/vias are large enough. This information should be available from your PCB fabrication house; ask them for their manufacturing rules document. section "Getting Started". gEDA PCB. How can I set color and thickness of the rats nests? used for nets. This sets the title attribute of the layout. The pads I've painstakingly created You will have to save and reload the layout to trigger recalculation of polygons so they are adapted to your edits. 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! You may need some trick polygon clearances to get power routing and routing within a board outline. Alternatively a restart will recalculate the polygons too. How do I trace a drawing, a print, or another PCB? Rectangular pads are ok, though. The line tool knows about different modes to deal with transversal connections. Else pcb won't let you connect the footprints with the copied tracks and vias. 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. Licenses: GPL Version: 1:4.2.0-1 website. 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). You may have to zoom out to get it on the screen. PCB seems to munge my components names and complains that it can't find proper nets for the pins! Another trick is to make a zero-length line. User Manual for PCB-v4.1.1-g8ab2fac2 an open source, interactive printed circuit board layout program by Harry Eaton and PCB Contributors If unsure, deactivate the far side with the “far side” button, at the bottom of the layer button row. What can I do about it? 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. 1:45. Don't end refdes's with lower case letters - they're reserved for gates within devices. Afterward, an object report pops up that contains the lock state in the last line. Lower case letters are meant to differentiate slots of a multi-component. chosen, or rounded up to the next size in the list. PCB will automatically create negative Gerbers on outer layer planes with no tracks. Tweak them to your needs and place them in a local library. History. KiCad . Now set the current layer to be the new layer. 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. The tab “Aperture usage” gives the number of SMD pads. You can use gerbv to extract this pad count from your layout. Spice.
