Processing of the Sealing Resin and Mold Resin X Grinding,

The solid-type sealing material is called transfer molding. Molding methods similar to mold injection are adopted. In transfer molding, after a pellet-type material is heated and softened in the plunger, resin is put into a mold, cooled, and solidified. The liquid-type sealing material is called potting. The resin is deposited onto the semiconductor die (bonded to the substrate) and thermal,Considerations for Mold Base Material Selection,,01/08/2013· The second material is a P20-type material that has replaced 4140 and P20 by two large mold base manufacturers in Europe. The reason for the switch was better machinability, and because this material is very stable—even during heavy machining and grinding—there is no need for stress relieving. Gun drilling is also much easier because the material does not have hard spots.
