An electronic unit has a circuit board that is integrated into an injection molded circuit carrier. A hearing aid is provided with such an electronic unit. In order to reduce the complexity and size of an electronic unit with an injection molded circuit carrier and a circuit board, the circuit board is integrated into the injection molded circuit carrier by introducing the circuit board into the plastic mold such that the surface of a first side of the circuit board lies within the plastic mold and the surface of a second side of the circuit board is substantially flush with the surface of the plastic mold. At least one conductive track of the circuit board is electrically conductively connected to at least one conductive track of the injection molded circuit carrier.

In still another embodiment, a removable cap (and a method for forming the removable cap) can be used for an electronic device housing.
Abstract:
The present invention relates to a method of making a hybrid wiring board. In accordance with a preferred embodiment, the method includes: preparing a dielectric layer and a supporting board including a stiffener, a bump/flange sacrificial carrier and an adhesive, wherein the adhesive bonds the stiffener to the sacrificial carrier and the dielectric layer covers the supporting board; then removing the bump and a portion of the flange to form a cavity and expose the dielectric layer; then mounting an interposer into the cavity; and then forming a build-up circuitry that includes a first conductive via in direct contact with the interposer and provides signal routing for the interposer. Accordingly, the direct electrical connection between the interposer and the build-up circuitry is advantageous to high I/O and high performance, and the stiffener can provide adequate mechanical support for the build-up circuitry and the interposer.
