Abstract:
Provided are interconnect circuits for interconnecting arrays of battery cells and methods of forming these interconnect circuits as well as connecting these circuits to the battery cells. An interconnect circuit may include a conductive layer and one or more insulating layers. The conductive layer may be patterned with openings defining contact pads, such that each pad is used for connecting to a different battery cell terminal. In some embodiments, each contact pad is attached to the rest of the conductive layer by a fusible link formed from the same conductive layer as the contact pad. The fusible link controls the current flow to and from this contact pad. The insulating layer is laminated to the conductive layer and provides support to the contacts pads. The insulating layer may also be patterned with openings, which allow forming electrical connections between the contact pads and cell terminals through the insulating layer.

A portion of the isolation channel is removed to mechanically isolate the MEMS device.
Abstract:
A lightweight radio/CD player for vehicular application is virtually "fastenerless" and includes a case and frontal interface formed of polymer based material that is molded to provide details to accept audio devices such as playback mechanisms (if desired) and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides EMC, RFI, BCI and ESD shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. The PCB architecture is bifurcated into a first board carrying common circuit components in a surface mount configuration suitable for high volume production, and a second board carrying application specific circuit components in a wave soldered stick mount configuration. The major components and subassemblies are self-fixturing during the final assembly process, eliminating the need for dedicated tools, fixtures and assembly equipment. The major components and subassemblies self-interconnect by integral guide and connection features effecting "slide lock" and "snap lock" self-interconnection. The radio architecture includes improved push buttons employing 4-bar living hinge linkage and front loaded decorative trim buttons.
