Dear SC, Are you looking for a cold solder detection tool for SMT,through-hole or both?

Fine crack in multi-layer ceramic capacitor (MLCC) may not be detectable by capacitance check.Could anyone out there advise which is the most appropriate method to test/detect fine crack ?

Rob's comments make sense. Responding to your question: * Sometimes you can see a resistance change * Sometimes you can see a leakage change

Thx for the replies. Acutally I am doing a process related study to see whether the process (pcb depanelling)can induce crack to an MLCC. After depanelling, I will do a thermal shock on the MLCC based on IEC 384-1, that is, five cycles of 30min at hi

Hi Ken, I know this doesn't help in the immediate timescale, but isn't avoidance the best form? can you trace the cracking to a process issue (Solder profile, shock damage, handling damage, probe/ATE damage)or a chip cap manufacturing fault? I can'

65%), if one failed on the board i replaced all of them, and re-tested and thermally cycled them inline with our spec (-55/+80 Deg/C for 48hrs) this was a nightmare, especially when some cracks were not detected until several weeks later while flying

Has anyone had success utilizing the lifted lead/ height checker feature on a Mirtec MV-7L. We recently had two separate events where the machine did not detect a lifted lead using the ic/bridge inspector. The soldering results came back with out def

Hi Refering to the Apr edition of SMT , page 24 to 29, anyone got experience on implementing the AOI or 3D x ray : a) What is the pros and cons? b) What is the trend in the PCBA industry for wave soldering inspection? c) Will this implementation co
