Dave, this is a massive question, and if you have any hard data on these issues, it would be wonderful if you could share it. The best I can offer is some indication of our experiences from contacts in the industry. Keep in mind as well, that we ha

Thank you for your response. I have been told that x-ray strength is finding solder volume and pattern root cause defects, and will catch a high % of them - opens, shorts, insufficient solder, and missing components(shape of solder on pad w/o lead i

I have to agree with Michael's comments. We've been evaluating systems for a month or so. There's a pretty wide range depending on what you're looking for. I'd say the first thing needed is to define your expectations. Are you looking for solder in

| | We've recently encountered this problem where one of our .050" pitch BGA's were reflowing at the wave thus causing shorts... The board was profiled with probes stuck to a QFP solder joint, an 0603, and one of the BGA joints. There was an almost
