Material Notes:

Test specimens were transfer molded and post cured 4 hours at 175°C.An epoxy molding compound optimized specifically for grid arrays (BGA/LGA) requiring low alpha particle count. It is formulated with a unique resin system which minimizes warpage and enables trouble-free molding onto laminated substrates. Minimal warpage (after post bake and solder treatment); Outstanding high temperature flexural strength; Low stress; Excellent moldability (low viscosity); Low alpha particle count
