[Elecraft] Solder Question...

[Trevor Jacobs]

Hey Gang,

I've always used 60/40 alloy solder (or 2% Silver for SMT) , but was
wondering about the 63/37 alloy? Was wondering what the purpose of the
different alloys was, other than the melting point (190 C for 60/40 and
183 C for 63/37). Is one more preferable for rework?

Also, anyone have a mail order/on-line source for Multicore solder? I
used my last roll up about a year ago and had been using Kester 60/40
#44 Flux and really liked the Multicore better. After checking the
Locktite web site, they don't seem to mention any part numbers, and
looks as though they are concentrating more on the "Lead Free" stuff. In
fact the only "Multicore" solder wire they mention in the product sheet
all has either "No Clean" or "Water Washable" Flux. Digikey doesn't have
it either. I wonder if this "Lead Free" stuff is going to take over?
Anyway, any information is appreciated.
