Experts, Is there any reference to the best wetting time when doing manual soldering in order to get the most reliable joints i.e to avoid thick intermetallic line formations. I heard people says, the shorter the better, but how short is short...sa

Dave, I am interested in a amine hydrochloride activated flux. Can you give suggestions on readily available fluxes that you have used that have strong deoxidization properties. I am looking at something that could be used in a pinch when the stan
