Abstract: A circuit interconnect may be used in biometric data sensing and feedback applications. A circuit interconnect may be used in device device-to-device connections (e.g., Internet of Things (IoT) devices), including applications that require connection between stretchable and rigid substrates. A circuit interconnect may include a multi-pin, snap-fit attachment mechanism, where the attachment mechanism provides an electrical interconnection between a rigid substrate and a flexible or stretchable substrate. The combination of a circuit interconnect and flexible or stretchable substrate provides improved electrical connection reliability, allows for greater stretchability and flexibility of the circuit traces, and allows for more options in connecting a stretchable circuit trace to a rigid PCB.

Abstract: Molded electronics package cavities are formed by placing a sacrificial material in the mold and then decomposing, washing, or etching away this sacrificial material. The electronics package that includes this sacrificial material is then overmolded, with little or no change needed in the overmolding process. Following overmolding, the sacrificial material is removed such as using a thermal, chemical, optical, or other decomposing process. This proposed use of sacrificial material allows for formation of complex 3-D cavities, and reduces or eliminates the need for precise material removal tolerances. Multiple instances of the sacrificial material may be removed simultaneously, replacing a serial drilling process with a parallel material removal manufacturing process.
