Setup Guy Thanks for the compliment. So, COB is not SMT. What is it? What kind of assembly areas do they use to print, place, reflow, and glob-top [or wire bond / encapsulate] COB? Any information you gave give to clairify this is appreciated.

I have one form a year 2006. Uses the studds to keep track of revolutions. Four wires going to the motor.

If you can't find bismuth wire, use 42Sn58Bi. For more, look here: http://www.mrs.org/s_mrs/bin.asp?CID=2274&DID=48689&DOC=FILE.PDF
