Abstract
According to some embodiments, the present disclosure is directed to a printed circuit board for a microphone assembly that includes a top layer structured for a MEMS transducer to be mounted thereon, a bottom layer, at least one edge, a ground plane, and a conductor electrically connected to the ground plane and the bottom layer. The MEMS transducer includes a transducer substrate, a back plate and a diaphragm. The conductor extends vertically from the top layer to the bottom layer of the printed circuit board, and horizontally along a portion of a length of at least one edge of the printed circuit board. The printed circuit board includes two short edges and two long edges, and the conductor is connected to at least one of the four edges.
