Abstract

A coplanar mounting member for a MEM sensor includes a first surface coplanar with a connection pad on the surface of a MEM sensor board containing the MEM sensor control circuit; a second surface inclined to the surface of the board for mounting a MEM sensor and an electrical conductor array for interconnecting the MEM sensor with the connection pad on the board.

Claims
