I meticulously made 8 sets of rca’s using Cardas 60/40 solder, while flushing with c02 and cleaned seald with deoxit G5 gold, and enamel clear coat over the solder joints. The problem lies with my flux. I used a self-cleaning acid zinc chloride flux. Should I redo them? Because I read In metallurgy articles that the joint will fail pretty quickly because of the wrong flux. I wouldn’t worry, but they are going to be installed were I can’t get them back out.
