[Boatanchors] Solder 63/37 Alloy, .015" Dia., #44 RA

[Mike Sanders K0AZ]

63/37 eutectic has a 1 degree plastic range. Been using it for a couple
decades now
commercially and hobby wise.

Unless, of course, you are working on an audio amp with tubes like
304TLs. Then you MUST, ABSOLUTELY MUST, use WECo 123 solder, made only
in the Oshkosh factory by Swedish elves, or our sound clarity may be
fatally impaired.

Actually, the 63/37 is eutectic and makes very nice joints. The Kester
44 has a good flux that does not corrode even after decades. It's the
stuff NASA and the USAF have used for at least 25 years.
