Abstract
Abstract A hybrid circuit module for the modular system constructions of electronic equipment. The module includes a socket that is soldered to a printed wire board and includes a grounding strip and electrical contact terminals. A hybrid circuit fabricated on a ceramic substrate fits within a plastic guide which in turn is fitted to the socket. A plurality of contact pads on the hybrid circuit make electrical contact with the terminals of the socket. A shield can is fitted over the plastic guide and hybrid circuit.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
148 words
A hybrid circuit module for use with a printed wire board, comprising: a circuit including a substrate and various circuit components thereon, said circuit including a plurality of contact pads formed on said substrate providing input and output connections for said circuit, a socket, adapted for connection at a first side thereof to a printed wire board and on a second side thereof for receiving said circuit, including on said second side a plurality of metallic terminals for mechanically grasping the ceramic substrate and making electrical connection with the contact pads thereof; a plastic retainer having a pair of grooves therein for receiving two sides of said substrate and a latch groove on a side thereof; and a can for surrounding and shielding said circuit, having a latch therein for mating with said latch groove, said can being electrically connected with said printed wire board through said socket.
Claim 2
Dependent Claim
