报告摘要:
The reliability of solder joints under mechanical impact loading is a major concern to portable electronics. Usually board level drop tests have to be conducted in order to investigate such a kind of issue. Nevertheless, the preparation of board level test samples is very costly and time consuming. The metrology for board level failure analysis is also very difficult and tedious. Therefore, there is always a demand for simpler test methods to investigate the solder joint reliability under mechanical impact loading. This presentation will introduce a package level test method and correlate the package level ball pull/shear test results to the board level mechanical drop test results. The basic requirement is the failure modes in both kinds of tests must be the same. Detailed failure analysis and data correlation will be given. The comparison of results justifies the feasibility of using package level tests to replace board level tests for the characterization of solder joint reliability under mechanical impact loading.
