  • Patent number: 7618249
    Abstract: A molding system for provided which is configured for molding a substrate comprising a plurality of individual carriers each of which is pre-cut into a shape of a memory card device and connected to a frame of the substrate by narrow tie bars. A molding plate is configured to receive the substrate, and a cavity plate configured to be clamped to the molding plate further comprises a plurality of molding cavities each constructed in the shape of the said carriers. The cavities are operative to create molded packages onto the carrier conforming to a shape of the memory card device without need for further forming of the molded compound after molding. Additionally, a nozzle on the surface of each cavity is operative to introduce molding material into the cavity in a direction that is substantially perpendicular to a plane of the substrate placed on the molding plate.
