Molding device and molding method

摘要

A molding device and method utilizes a cavity including fast and second parts for molding an article having one or more convex portions and a gate for injecting mold resin into the cavity. The gate in turn includes one or more gate sides for injecting resin into a concave portion of one part and a gate base for injecting resin into a second of the parts in which no concave portions are located, both resin injections occurring simultaneously and substantially encapsulating a semiconductor element to form a molded article having a convex lens.
