Using Eagle 7.6.
I have a part in a TO-5 can. The can needs to mount flush to the PCB, and I'm concerned that the copper on the top side of the standard thru-hole pads might contact the case. For various reasons can't put an insulator between the part & PCB - the part MUST be hard against the PCB.
I could make the pad's diameter really small, which would help the top side, but would provide no real estate for soldering on the bottom. So what I really want is a "single sided" pad - essentially a non-plated hole with a solder pad on the bottom side and bare board on the top.
Any suggestions as to how to best create this?
My thought was to make a zero-width (ie. filled) circle on the bottom (or pads) layer, put a slightly larger bStop filled circle on top of that, then place a 0.025" hole in the center of it all.
Any thoughts/suggestions/opinions would be appreciated, -Dave
