ABSTRACT:
A multi-channel pressure sensor module (10) for integration in a hydraulic/electrical control unit of a vehicular braking system is shown. A body or manifold (16) mounts a plurality of strain gauge sense element assemblies (12) each having a port for connection to a fluid pressure source to be monitored. An electronic module assembly (14) has a contact printed circuit board (24) and a sense element printed circuit board (22) sandwiching a spacer/support member (20) and electrically coupled together by a flexible circuit board (26). The spacer/support member (20) is formed with pockets (20e,20f) for receipt of discrete electronic components and to provide access to wire bond pads (22c) and sense element openings (22b). First and second sets of guide posts (20c,20d) extend from the spacer/support member for alignment of the circuit boards as well as the electronic module assembly on the base. A cover (18) is received on the base over the electronic module assembly and provides access to contact pads of the contact printed circuit board through a shroud (18d).
