I have a 1 lb spool of kester solder that I am trying to identify to see if it is ok to use on a kit. I can't find the specific information anywhere on the web as to it's characteristics. Here is what is on the spool: Alloy = SN63 Core = 66 (or might be 06, hard to tell) Flux = 254 Dia = .031 I can't seem to find anything listed with a flux of 254 Anyone familiar with this and would it be ok to use? Thanks Tim NZ8J
