Abstract:
1. A method for producing a plurality of MicroSD devices, the method comprising: producing a printed circuit board (PCB) panel including a plurality of PCBs arranged in a plurality of rows, wherein all of said PCBs have a first width, and wherein at least one said PCB in each row is connected to a first adjacent PCB by a first connecting bridge structure and to a second adjacent PCB by a second connecting bridge structure, wherein the first and second connecting bridge structures have a second width that is narrower than the first width, and wherein the PCB panel defines a plurality of elongated stamped blank slots defined on the sides of each row such that side edges of each said PCB are exposed, attaching at least one passive component and at least one integrated circuit to each said PCB; forming a single-piece molded housing on a second surface of the PCB such that said at least one passive component and said at least one IC die are covered by said molded housing, and portions of said molded housing cover said side edges of each said PCB, wherein said first connecting bridge structure and said second connecting bridge structure extend from opposite ends of the molded housing formed on said at least one said PCB in each row; wherein forming said single-piece molded housing comprises disposing said PCB panel into a first molding die including a plurality of raised island structures, each raised island structure being received inside a corresponding one of said elongated stamped blank slots such that a predetermined gap is defined between each side edge of each said PCB and a corresponding facing wall of an adjacent raised island structure; and singulating said PCB panel after forming said single-piece molded housings by cutting said first and second bridge structures using a rotating blade, thereby providing said plurality of MicroSD devices.
