Bob, Depending on what your time frame is, we may be able to work together. JPL is managing a consortium to assess the reliability of BGA soldered interconnects. We are fairly well along in the project. Members include: ITRI, IBM (East Fishkill & Canada-Celestica), Boeing, Hughes, Altron, Rochestor Institute of Technology, the EMPF, Amkor Anam, and Xetel. We've designed the test vehicles and are ready to begin assembly (middle of October). We have 200 test vehicles with four parts each. We are testing 9 different part types which are centered on 300 and 600 I/O. We have OMPAC, SuperBGA, perimeter and full arrays. We also have a 560 I/O SuperBGA which will be power cycled to failure. We may be able to use your services following assembly for inspection. This would give you data and since we plan on testing to failure, quantifiable criteria. We are currently negotiating with Nicolet and Microfocus but would like to talk to you. Give me a phone call at your convienence. Regards, Phillip R.

If there is no in-house standards that people want to discuss I will need to pick one out of the air. A am currently compleating an inspection video for x-ray covering chip, J lead, gull wing and BGA terminations and need to have some input on the criteria used on these types of joints. I have already used the x-ray on my BGA training video but would like some basic criteria. If any one has a standard that they use for assesment and is willing to provide the criteria then the best can have a FREE copy of the tape when compleated.
