Kester 24-6337-7604 SN63PB37 50 Core 275 Flux Solder Wire .15 Dia

Kester 24-6337-7604 is a 1 lb spool of leaded, no-clean, cored-fluxed solder wire in a .015 diameter. It is comprised of SN63PB37, or 63 percent tin and 37 percent lead. Additionally, it has a 50 core size and a 275 (no-clean) flux type.
Kester 275 No-Clean Cored Wire for Lead-bearing and Lead-free alloys.Kester 275 No-Clean Flux for cored solder wire was developed to provide superior wetting performance for hand soldering in the electronics industry. The chemistry is based on some of the same principles that have been safely used for years in mildly activated rosin fluxes. The use of 275 No-Clean Flux results in an extremely clear post-soldering residue without cleaning. The unique chemistry in Kester 275 was also designed to reduce spattering common in most core fluxes. Kester 275 can be used for both lead bearing and lead-free soldering.
