Hi manchella, After ATC test, two different failure modes can be present: solder FATIGUE (into bulk) or BRITTLE INTERMETALLIC fracture. So, first you have to verify this. Moreover, which brand of SMT paste have you used ? The crack into solder joint

Interesting, we have a SMT division, that caters to the exact scenario you depict... Actually am also trying to determine, a system of answering "high mix, low volume" picture... Just my humble point of view, dun think there is "best" system in th

HELLO. SMTNETERS there is no company in high mix low volume system in our contry so . what is the best way to calculate the capa. of smt line in high mix low volume. & what is the general way to get the defect rate to evaluate the smt line(or sm

| Has anyone had issues where bottomside double reflowed smt has fallen off in the wave when using voc-free flux? I have verified the hotter profile was not the issue by using an alcohol based flux with no problems.This voc-free flux is also not caus
