ABSTRACT:
A ceramic capacitive pressure transducer adaptable for use in automobiles is disclosed. The pressure transducer comprises a relatively thin diaphragm 13 having a capacitive electrode 20 thereon, a base substrate 10 having an opposing electrode 22 thereon, and an annular sealing ring 16 mounting the diaphragm to the base substrate. The base substrate has a peripheral lead bonding area 24 extending laterally beyond the perimeter of the diaphragm with two lead through holes 25, 26 in the bonding area. Metallic output leads 35, 36 are positioned in each of the lead through holes and mechanically and electrically bonded to lead metallizations 27, 28, 30, 31 deposited on the base substrate peripheral portion 24, and one (36) of the output leads is electrically connected to the diaphragm electrode 20 by means of a conductive material 37 inserted through an additional hole 33 in the base substrate located within the perimeter of the diaphragm and in an area of overlap between an outward radial projection 21 of the diaphragm electrode and an inward projection 32 of one (28) of the lead metallizations on the base substrate.
