Abstract: A sensor assembly comprises a rigid substrate with a circuit subassembly wrapped therearound. The circuit subassembly includes a flexible substrate with conductive traces and interconnects formed thereon, and when wrapped around the rigid substrate, the conductive traces may overlap one another so as to form capacitive sensor elements. The interconnects connect the conductive traces to one or more components, such as a printed circuit board attached to a portion of the flexible substrate. The sensor assembly maybe installed in an opening formed in a host device panel of a host device, such as a smart phone, with the sensor assembly optionally peripherally surrounded by a spacer frame, and covered by a cover element. The circuit subassembly may include a host connector tab for electrically connecting the sensor assembly to electrical components of a host device.

Abstract: A sensor assembly includes a flexible substrate with conductive traces formed on opposed sides of the substrate and oriented transversely to each other. The substrate is wrapped around a core so that the traces formed on opposed sides of a first part of the substrate form a first sensor surface on one surface of the core, and the traces formed on opposed sides of a second part of the substrate form a second sensor surface on an opposed surface of the core. The core may comprise an encapsulant overmolded onto the conductive traces on a surface of the first part of the substrate, and the second part of the substrate is folded over the encapsulant. The sensor assembly may include an integrated circuit disposed on the flexible substrate, wherein one or more of the conductive traces are electrically connected to each integrated circuit.

Abstract: A plurality of molded cover members are manufactured by first singulating a single sheet of cover material, such as glass, into a plurality of separate, discrete cover members, placing the cover members in spaced-apart positions on a releaseable carrier, and applying a molded material to the perimeter of each cover member. The molded material can be applied by a blanket molding technique whereby gaps between adjacent cover members are filled, and then the cover members are singulated, leaving a portion of the cover material on the perimeter of each cover member, and then the singulated, molded cover members are released from the releasable carrier. Alternatively, the molded material is applied by a patterned molding technique whereby molding material is applied to the perimeter of each cover member without fully filling the gaps between adjacent cover members, and then the molded cover members are released from the releasable carrier.
