You can try "slotted solder terminals". For example: https://www.mill-max.com/assets/pdfs/243.pdf These are designed to be swaged/staked into a PCB so they won't come loose when the solder at the bottom melts. The 3622 is press fit into a plated hole. Of course if the Chinese bother to make these they'd probably be 1/10 the price. --spehro --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
