Check with Motorola. They put out a great deal of data some of which compares QFP with BGA. > Jason L.

I am taking a part-time Master degree and have to submit a 15-20 pages long assignment on a topic of our own choice on the subject of reliability as part of the coursework. As I am a SMT manufacturing engineer in practice, I would like to do a term paper comparing the reliability between BGA and QFP package. Technology and science have helped in the miniaturisation of most of our electronic products but are their reliability as good as those that are used during our grandparents' time? If anyone has access to any literature on this aspect, could you email them to me? I have searched through Compendex Plus but is disappointed that the literature that I need is not available in the libraries here. If anyone of you could provide me with some experimental data, that will be great. Please email me off list for any correspondence. Thank you! regards, Boon Kiat Singapore ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information.
