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). Using an improved optimized filler system, it provides a lower viscosity with higher flow characteristics than SMT-B-1. Minimal warpage (after post bake and solder treatment); Outstanding high temperature flexural strength; Low stress; Improved wire sweep performance (low viscosity)
