Abstract In a prequalification effort to evaluate the assembly process for the industrial grade high pin count devices for use in a high reliability application, one device exhibited characteristics that, without corrective actions and/or extensive screening, may lead to intermittent system failures and unacceptable reliability. Five methodologies confirmed this conclusion: (1) low post-decapsulation wire pull results; (2) bond shape analysis showed process variation; (3) Failure Analysis (FA) using state of the art equipment determined the root causes and verified the low wire pull results; (4) temperature cycling parts while monitoring, showed intermittent failures, and (5) parts tested from other vendors using the same techniques passed all limits.

Temperature Cycling Test

Two kinds of import laptop battery and one kind of domestic laptop battery were investigated in the temperature cycling test. The results showed that all the samples didn’t fire, explosion and leakage in the temperature cycling tests. But the shell glue of domestic laptop battery was disabled more serious then that of import laptop battery and it still exist some security risk.Therefore, There is a long way to go to investigate and improve the quality and safety performance of some laptop battery.
