kenemon 29 Posted December 4, 2011 Share Posted December 4, 2011 Hey, has anyone had round PCB's made? I have an issue will my gerbers made with design spark software. Apparently the CNC software cannot understand the dual arc circles?? it has a 12mm diameter if this is of consequence. Quote Link to post Share on other sites
cde 334 Posted December 4, 2011 Share Posted December 4, 2011 Afaik, and this is 3rd hand knowledge, most pcb services dont like cutouts like that. If the center is supposed to drop off, it will reject it. Keep a little tab on the circle to keep it attached, and cut it off yourself later on. kenemon 1 Quote Link to post Share on other sites
kenemon 29 Posted December 5, 2011 Author Share Posted December 5, 2011 Thanks cde, I have done rectangular cut outs without a problem, I think the issue is a circular one, but I wouldnt doubt it. Quote Link to post Share on other sites

You've done large cutouts inside the board? Like a square inside a rectangle? Which service do you use? Quote Link to post Share on other sites
kenemon 29 Posted December 5, 2011 Author Share Posted December 5, 2011 yes cde, see http://www.43oh.com/forum/viewtopic.php?f=30&t=1516&start=30#p11446 for some info. It was made using designspark and Seeed fusion service. You actually add a "board" to your board, placing it inside the outline perimeter. Interestingly, there are no tabs on them..... On another note: I was able to get a circle with four segments, using a square, and 90 degree arcs on each side. We will see if this has any improvement on the feasibility.
