A new fast moisture sensitivity analysis method using equal moisture distribution simulation

MSLA, the abbreviation of Moisture Sensitivity Level Analysis, is the meaning of moisture sensitivity level analysis. MSLA is to give the proposed package moisture sensitivity of surface mount components provide a standard of classification, so that different types of components to get the correct packaging, storage and handling to avoid moisture resulted failures in the assembly or repair process. But traditional moisture sensitivity level characterizations take long time even the fast level 1, 85°C/85%RH conditioning needs 168 hours. The purpose of the paper is introducing a fast moisture diffusion method using high temperature and high relative humidity to increase moisture diffusion speed by numerical simulation, which will assist the moisture diffusion time.
