Abstract: Systems, apparatus, methods for manufacturing and techniques for interconnecting integrated circuit devices are disclosed. A flexible printed circuit (FPC) provides EMI shielding with reduced insertion loss. The FPC includes a first signal layer fabricated from a planar conductive material and having traces configured to carry signals between a circuit boards. The FPC may include a first non-conductive layer disposed in a plane above the first signal layer, a second non-conductive layer disposed in a plane below the first signal layer, a first copper ground plane disposed in a plane above the first non-conductive layer, a second copper ground plane disposed in a plane below the second non-conductive layer, and a second signal layer provided in a plane above the first copper ground plane or below the second copper ground plane. Signals carried in the first signal layer may have a higher frequency than signals carried in the second signal layer.

Abstract: Combined sockets for selectively removable cards in computing devices are disclosed. In one embodiment, a socket is provided that can accommodate both a subscriber identification module (SIM) card and a secure digital (SD) card. The cards are held in place within the socket in a back to back configuration by springs which further help insure that contacts on the cards are electrically coupled to conductive pins in the socket. While it is contemplated that the socket will be used in mobile terminals such as smart phones and tablets, the socket may be used in other computing devices that use such cards.
