Kester 245 No-Clean Flux Core Solder, 63/37 .020", 1lb
Kester 245 No-clean Cored Wire was developedto complement low residue liquid fluxes being usedby the electronics industry. The chemistry isbased on some of the same principles that havebeen safely used for years in mildly activated rosinfluxes. The use of 245 No-clean Cored Wireresults in visually acceptable assemblies withoutcleaning, yet soldering quality and efficiency iscomparable to that obtained with mildly activatedrosin flux.
