" so I wander what can I do to save them?" The boards or management? Seriously I think this is more of a management issue than a technical issue. We can suggest what to do but if management does not accept that solution then it won't work. I'm not s

Hi, I'm looking for research/study done on solder shelf life by using accelerated aging process ( steam age or dry air oven bake at 150C & etc ) Perhaps you could help to advise correlation of all this acceleration test to actual solder shelf life

Hello all, I'm working at a CM with less then ideal material storage shelving when it comes to ESD protection. I've got ordinary painted shelving units that I need make ESD safe. I'm considering dissipative mats or spray coatings for each shelf, t

Gary, Paladium Leads have been a win-lose proposition as far as I can tell. The vendors win because they don't have to deal with lead and get higher yields. The users lose because of extra engineering time involved with incorporating this on their

I have boards with bad HASL application. First they're not even. Second some pad edges have no HASL and still remains bare copper. What's the maximum and minimum HASL thickness required for a good solderability. My boards are about 6 weeks old, I kno

What type of board finish ? I've seen this same defect with QFP's on some of our HASL boards. Best I can tell either the PCB's have poor solderability or uneven pad heights due to poor solder leveling at the PCB fab. Newer PCB's seem to yield bette
