I have a couple of things that I am having trouble with. The first is the board mounting holes. I just do not see a way of putting them in without creating a...
... I don't think you can add a mounting hole without it being a part. I was told to always add parts to the schematic for mounting holes and any other...
This function does not seem to work correctly. I get the right multiples of images but not the spacing I entered into the edge to edge spacing box. Is this a...
Chris, It works but maybe not the way you expect. The "Number of boards" X and Y is obvious but the "Spacing edge-edge" refers to the gap between copies not...
Okay...I did it again...350 mils is not .350! that is the second time this had gotten me. Actually, I found the step and repeat in the gerber viewer and got...
- Where can I find a big Land Pattern library that can be used in Free PCB? - Can I import land patterns from the PCBLibraries program? - If so How? Greg...
Hello,i am a new user of FREEPCB,it's really powerful as a freeware.but while designing with it,i wonder if it has these two features: 1,Could FREEPCB set...
Greg, Someone has done that for us. Go to http://www.freepcb.com/ click on downloads, there you will find IPC7351-Least_v2.zip, IPC7351-Nominal_v2.zip and...
Not too sure what you want here. 1. sounds as if you are intending to use the autorouter. I believe there are methods to set a keepout for this - see the...
Philip,thanks for the reply,Let me clarify more 1,Actually,i wanna set an area which can't be routed,this area can keep out the routing trace automatically.So...
Try Freeroute with a small design to start with. Make sure you have a board outline defined. I just tried it and it worked OK. I think the 'KeepOut' uses a...
Hi Leon, Please read the FpcROUTE User Guide to see how to run a FreePCB project through Freerouter. The guide is included in the FpcROUTE distribution archive...
I can not seem to get the 'FPC Poly' program to install. I followed the install directions and still the screen just blinks and the program does not...
Hi Greg, Sorry to hear you're having trouble. If you are running under Vista, I think you need to be logged in as administrator to make changes/additions to ...
It is harder than that actually. A program that wants to write to a directory under Program Files is looking for trouble. The way that has been recommended...
As I zoom in on a via and begin to strip away the layer views, it seems that the via makes electrical contact with all layers. Is this true? Is a via a...
Greg, Yes the via goes through the whole thickness af the board, FreePCB does not do blind vias. The via in your example should not connect the the ground...
It was recommended that I use vias to connect the 2 ground planes at various points in the board to ensure that the ground planes on my 2 layer board are not...
... The short answer is no, vias can only be added to traces. But don't give up, it can still be done. In no-mans land, you'll need to add a pin. Create a...
To what point (or end) should I be concerned with thermal dissipation and impedance values in the traces on my board? How do I calculate these values? - The...
... The thermal issues depend entirely on your design. But if you aren't doing anything weird, RS-232 and USB shouldn't require any thermal consideration. ...
Greg, Overall power dissipation depends mainly on component size, placement and air flow. A few large parts, spread out over the board, can obviously dissipate...
Greg, I am using version 1.354 and you can with it. Go to Project/Options and change the number there. I cannot say if this works in older versions, I do not...
Here's probably a majorly dumb newbie question, but with FreePCB is it possible to design oddball pads/traces for contact switches like those used under rubber...
