A method for producing a finished multimedia card (MMC) in a single molding operation in a second stage manufacturing operation. The first stage involves obtaining an already molded top plate and an already assembled printed circuit board (PCB). The second stage involves placing the molded top plate and assembled printed circuit board together in a mold assembly and then placing the mold assembly in an injection molding machine. The printed circuit board is thus only exposed to a single molding operation in order to produce a finished multimedia card such as a memory card. The single molding operation produces an improved quality multimedia card.
