Abstract

In the semiconductor industry, during the component level reliability evaluation, the non-accelerated soakage testing in the precondition is normally proceeded, which takes much time. In order to reduce the soaking time, three accelerated soaking conditions are studied with reference to non-accelerated soaking condition (JEDEC Level 3 and JEITA Rank E). Under the three accelerated soaking conditions, the moisture gain and moisture distribution are studied and confirmed by FEA (Finite Element Analysis). Also, the failure is studied under the three accelerated conditions compared with those of non-accelerated soaking conditions. Thereby, the time to fail of the component is determined.
