The problem you describe is exactly the first problem I had with FreePCB. When you want to connect a pad to a plane, you don't just Wed, 16 Sep 2009 02:09:29 GMT Ron Tonneson http://tech.groups.yahoo.com/group/FreePCB/message/599 http://tech.groups.yahoo.com/group/FreePCB/message/599 Barry, Don't get mad. I am not sure I understand what you are doing. If you would want to send me your file attached to a private email I could try to help. Wed, 16 Sep 2009 02:01:15 GMT hofcuse http://tech.groups.yahoo.com/group/FreePCB/message/598 http://tech.groups.yahoo.com/group/FreePCB/message/598 This seems to be a particular problem when using plane thermals. FPC has a ratline between two pads, but if you run both pads to vias, the ratline remains.

It means that you connected the traces with copper, but not in a way that FPC understands that you Wed, 16 Sep 2009 00:04:25 GMT hofcuse http://tech.groups.yahoo.com/group/FreePCB/message/596 http://tech.groups.yahoo.com/group/FreePCB/message/596 Thanks Ron, you're a lifesaver. Now, what about those ratlines that remain even though a trace exists? I expect that there will be errors generated (which I Tue, 15 Sep 2009 15:06:17 GMT Ron Tonneson http://tech.groups.yahoo.com/group/FreePCB/message/595 http://tech.groups.yahoo.com/group/FreePCB/message/595 Barry, That is a nasty bug in version 1.355, go back to 1.354 and you will be in good shape.

I'm laying out my first board with this software, and realize I'm way down on the learning curve, but I'm having some Thu, 23 Jul 2009 20:18:06 GMT Bruce Parham http://tech.groups.yahoo.com/group/FreePCB/message/593 http://tech.groups.yahoo.com/group/FreePCB/message/593 Hi S, The short answer is yes. The trick is to create a footprint that uses overlapping pins. I did a short tutorial PDF, a few weeks back, about how to use Thu, 23 Jul 2009 17:06:03 GMT shaddow_1971 http://tech.groups.yahoo.com/group/FreePCB/message/592 http://tech.groups.yahoo.com/group/FreePCB/message/592 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 Wed, 08 Jul 2009 16:22:19 GMT Ron Tonneson http://tech.groups.yahoo.com/group/FreePCB/message/591 http://tech.groups.yahoo.com/group/FreePCB/message/591 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 Wed, 08 Jul 2009 15:52:58 GMT SapphireGin2 http://tech.groups.yahoo.com/group/FreePCB/message/590 http://tech.groups.yahoo.com/group/FreePCB/message/590 In FreePCB, can I add or subtract layers after I have started a project?

A few large parts, spread out over the board, can obviously dissipate Tue, 07 Jul 2009 16:36:07 GMT Rick Collins http://tech.groups.yahoo.com/group/FreePCB/message/588 http://tech.groups.yahoo.com/group/FreePCB/message/588 ... 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.

How do I calculate these values? - The
