Dreamy It sounds like you are having fun in your new job. Saponifier. Alkaline chemicals, added to water, that convert rosin/resin flux residues in the water to soluble soaps. Generally, saponifiers are better if used in an aggressive spray-in-ai

I assumed the balls were tin/silver 221C or tin/silver/copper 218C liquiduous....but, this is obviously not the case. It looks like you balls are almost pure tin (mp=238C) You are correct. This is exactly the same as using 10/90 high temp balls o

Additionally, increases in temperature can increase the water's rate of reaction with the flux. Sometimes, only a 5 degree change can make the cleaning difference. If the flux inconsistently presents itself, then the likely cause is something in

Because the HASL process most deal with bare metals, HASL flux residues are generally more active than solder paste residues. Typically a Rosin Active (RA) flux is used in the HASL process. These flux residues should be removed from the bare board
