Tin Whiskers (on terminal lugs)
We use terminal lugs made from brass with electrotin finish. The terminal lugs are used for electrical ground. Is tin whiskers a problem with this material and finish? Would solder dipping the terminal lug in SN63 solder reduce or eliminate the risk of tin whiskers?

Tin whiskers is a problem on pure tin. If you co-deposit a little bismuth or use a tin/lead bath no problem. Reflow also is a cure, as id the solder dip you suggested. Of interest is that one of the things that favors whisker growth is under compressive stress....like a lug bolted down
