Statement of Work & Project Statement
Electronic packaging is made up of polymeric materials (dielectric, solder resist, core, mold, epoxy, etc.) that absorb moisture from the environment during substrate fabrication, packaging assembly and test processing. Absorbed moisture can cause material hygroscopic swelling and induces hygro-stress, which can lead to component warpage, delamination or popcorn failure during reflow or reliability tests.
Knowledge of the moisture properties of polymeric materials (diffusivity, concentration, hygroscopic swelling) is critical for optimizing package material and design to minimize moisture-related failures. Hygro-swelling properties are not widely available due to a lack of measurement methods, and existing commercial measurement techniques have limited temperature capability (20-120°C).
The ultimate goal of this iNEMI project is to give materials companies a better understanding of quantifiable material properties at higher temperatures and moisture concentrations to enable them to develop innovative new materials that minimize the risk of failure due to moisture and humidity.
