Morning all, we have been seeing some problems with the edges of some of our BGA's curling away from the PCB after reflow. Is this possibly a moisture problem? If so what would be a good time/temp to bake them at to rectify the problem? Thanks in

JDumont: In trying to find the paper that Francois referenced, poke around his site [ http://www.cogiscan.com ], where he's collected a bunch of papers on the control of moisture sensitivity in components.

Yes i was looking around that site this morning and found everything i needed. Thanks to all. Basically what im trying to do is justify the expenditure of a new NO2 generator for our IC cabinets. Ours died a little while back and we have been using

There multiple potental causes of BGA curling during reflow. One of them is moisture inclusion in the part, as Francois mentiones above in this thread. Another has to do with the construction of a BGA. So, from our perspective, more often the mois

The answer is yes, it is possibly a moisture-related problem. You can confirm this by baking your parts at 125C for 48 hours (ref. J-STD-033A, table 4-1). For more technical background on this issue I recommend you read the following paper : Impac
