Hello gentleman, I saw many topics regarding aoi verification but I didn't see how You handle with board with simulated failures during life time, because we Are facing issue with ageing of tin oxidation. Is it any idea how to solved this issue?

Thanks Dave. Talked to a few people at APEX this week and if nothing else, had my frustration reduced some. Of course I made sure I talked to mfg. people and avoided the design guys like the plague. ;) I actually picked up a copy of 785 a while bac

I've got a question: Can a joint look good externally, even under 45X magnification, and not be mechanically and/or electrically sound? I thought that if the wetting angles were sufficient, there's no discoloration from extreme thermal distress, or

Let me make several points on this issue � POINT 1: Let�s be basic � Soldering and welding are examples of process that the quality types call "special processes". Special process. The results of special processes cannot be verified fully by subs

Hi folks! TI told us that we are the only one with the following problem... We discovered a really bad wetting characteristic of some SMD ICs from BurrBrown. At the moment: XTR106 / INA118 / ADS7844. After the reflow process we found out that this pa
