Review on Premium Kester 331 Organic Core Solder 63/37 .031 1 lb. Spool for Efficient Electronics Soldering by NTE Electronics (1) by Gerald Barrett

The Best - Welding and Soldering

Kester make the best solder and this is no exception, it is the highest quality solder, it is a water wash flux, and it smells like shit compared to kester 44s flux but it flows just as easily and melts very fine solder perfectly, i would recommend that you use a sponge if cleaning the tip between uses as this flux is caustic and rinses off needs to be, but other than that it's a great material.
