ABSTRACT:
A portable memory device includes a molded housing and a printed circuit board assembly (PCBA) encased with the molded housing such that a plug connector extends from one end. A lower housing portion is produced by injection molding using a first apparatus, and then the lower housing portion is transferred to a second molding apparatus. The PCBA is mounted onto the lower housing such that the plug connector is received in a protected region. The second molding apparatus is then closed, and an upper housing portion is injected molded over the PBCA and exposed peripheral edges of the lower housing portion such that the upper housing portion becomes fused to the lower housing portion. Multiple lower housing portions connected together by plastic tethers to form a plastic strip, which facilitates efficient transfer to the second molding apparatus as a unit. The tethers are subsequently removed (e.g., singulated) to form individual memory devices.
