I shoveled out this morning before coming in to work! It's a good workout! I can see the benefit of using them on the bottom side, but I'm seeing them on top also. Regards, Gary Gary E.

That way I can keep the decoupling caps and termination resistors right there. Works fine, haven't had any yield problem.

So, I've been looking at some designs from a couple of other groups within the company. Both of them have their 0402 and 0603 foot prints with round pads (0402 = rd25). Is anyone out there also using round pads for 0402s and 0603s, and why? They have oval pads for their 0805s and 1206s also. I still have square or rectangular for all of the above. Could it have something to do with lead free? Thanks and Happy New Year! Gary Gary E. MacIndoe PCB Design Engineer Longmont, Colorado amd.com gary.macindoe@xxxxxxx
