Here is another question for all you gurus.
We have a hand build, through hole circuit board that has 8 locations that must be free of solder for the next level of assembly. So far I can only find solder mask tape dots at Contact East. Are there any other suppliers out there? Our terminal measures 0.28 inch diameter, so a 0.3" pad might be just the thing.
Thanks in advance,
Phil
