Patent ID: 7663214

Claim:
A memory card assembly, comprising: a printed wiring board substrate having upper and lower surfaces, the printed wiring board having a contact pad engageable with a reader device, the contact pad disposed on the lower surface, the printed wiring board defining an outer substrate periphery; at least one integrated circuit unit mounted and electrically connected to the printed wiring board substrate; a filler resin material applied over the printed wiring board substrate and the integrated circuit unit; and a rigid retaining member defining an inner retaining periphery being less than the outer substrate periphery, the rigid retaining member having an inner sidewall fitted over the printed wiring board substrate, the retaining member being operative to retain the filler resin material as it is applied over the printed wiring board substrate and the integrated circuit unit, the rigid retaining member defining an outer periphery that is engageable to the substrate upon vertical translation, the inner sidewall defining a variable sidewall thickness along an intermediate portion of the inner sidewall and forming a notch in the vertical direction at approximately the center of the inner sidewall, the notch pointing outwards into the rigid retaining member.
