Never heard of the DRS-22C. I have had a DRS-22 for several years now. Purchased it when we started doing BGA's. The operators like it - good optics (split view), built like a tank, X-Y table easy to manipulate for alignment. I like it because I ca

Richard, your asking a multi million dollar question that in my own opinion no one can give you the right answer since no one really knows. hence I think the lack of answers to your question....thought there would be more people willing to propose a

| | | Does anyone have any experience with vibration testing of BGA packages and assemblies? We are starting to design BGA's into some of our products and we have not found very much information on vibrational test results. Any information will be

Selective Soldering Frames can pull large amounts of heat from the solder wave at the point of contact, effectively lowering the temperature of the solder at the solder joint. You should confirm the temperature of the solder joints by running a therm

I'm confused. A paste Supplier suggested to turn off nitrogen during reflow because it is one source of voiding of bga solder joints...is this true? regards, Dreamy

Why you do not try by yourself ? Run some BGA reflow with and without N2 then X-ray the solder joints. Regards GS

Since your problem has been posted quite some time ago I am eager to know, if you have got any clue. One of my customers recently claimed our 313-PBGA causing problems, as one of its balls (randomly) is almost dewetting. So no evidence is found by x-
