I am looking for justification information with respect to Accelerated 
Reliability Testing of Surface Mount Devices (BGAs in particular)

     Anyone w/ experience w.r.t. accel life testing as defined in IPC-SM-785 
(Nov 92)
          design of test vehicle
          structure of tests

     What about sample conditioning?  Is it necessary? Do people do this?
          (ref IPC-SM-785 7.9.5 - Sample Conditioning)

     What about cycling ramp rates and how are they significant?

Please contact Bill Goers at [log in to unmask] or (317) 
226-5627 if you have any background information about Accelereated 
Reliability Testing.

Thank you
