As an addendum to Daves posting, please consider that: There is no such thing as no residue fluxing. A no-clean must herefore, have benign residues - in other words, they are not as efficient at removing surface oxides to enable good solder joints. S

Hi all, by reading along those thread (SOT23) and Tan outgassing I learned plenty of things. My first time approacing this kind of Q$A Forum, very intesting tech communication way. Any way, the path of magnetism effect was chosen when time ago we met

We are having the exact same problem! We do about 6 or so ROHS SMT builds. 5 are fine now but we had problems with most initially and 1 is trouble still. All boards are same material, same PCB manufacturer. Initially, when the delam. problem occu

How many % were affected? If a few,it can be caused bcoz of PCB coating. We had encountered it and PCB house replaced for faulty boards. Since then, we do test first if we hve to solder PCBs from this PCB house.
