This silver loaded one is normally used for SMD soldering to minimise silve= r leaching from the lead terminations on resistors and capacitors as they t= end to use a silver based termination. Also my understanding is that a non-lead based solder makes the best solder= ing joints, provided they are properly done. --=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 .
