Technetters I have some questions that could be helpful to my thesis about PBGA reliability. I'm planning to perform accelerated thermal cycling (ATC) to PBGA components, and 1. Equipment with thermal cycling between -10C to 65C with a heat rate of 1C/min is available, Could this cycles be optimum to obtain reliability data? 2.Where can I find information about ATC suitable to PBGA? 3. Does IPC-SM-785 is applicable to PBGA? Alejandro Becerra Research assistant Laboratory for Electronic Manufacturing ITESM, Monterrey, N.L.
