Manufacture of memory cards for, e.g. storing computer data, involves making memory card by plastic injection molding to completely wrap chip module having flash memories, control chips, and passive elements inside the card into plastic

摘要

Memory cards are manufactured by forming a base and chip modules by passive elements, flashing memories, and control chips installed on the base; forming a circuit connection by the chip modules and contact terminals in front of the base. The base contains chip modules made directly by a plastic injection molding method to wrap the chip modules on the base in a plastic, assuring that the chip modules are sealed and isolated.
