Integrated interconnect for a back-firing microphone circuit board

Abstract

A circuit board assembly includes a top circuit board forming a microphone aperture and carrying electrical conductors. The circuit board assembly further includes a back-firing microphone connected to the top circuit board, the circuit board assembly providing support for the microphone, and the microphone electrically connected to the electrical conductors. The circuit board assembly further includes at least one interposer connected to the circuit board assembly, the at least one interposer positioned to the side of the back-firing microphone and including vias for providing a pathway for electrical connection to the top circuit board conductors.
