Method for achieving the electrical and mechanical interconnection of

Abstract

A method for achieving mechanical and electrical interconnection of first and second bodies of which the first has at least one conductive element its surface intended to face the second and the second has a through-hole for electrical connection provided with a metallic coating intended for electrical connections to the conductive element of the first body includes applying layers of vitreous glue to corresponding surface portions of the first and second bodies. Moreover, a coating of conductive material in a vitreous matrix is deposited by the thick film technique on the surface of the second body intended to face the first, adjacent the through hole with the coating extending at least partly into the hole and electrically connected to the metallic coating of this hole. The bodies are then joined bring the respective layers of glue into contact with each other and the conductive coating of the second body into contact with the conductive element of the first. The two bodies thus joined are then passed through an oven where they are heated so as to achieve the simultaneous fusion of the layers of glue and the sintering of the conductive coating applied to the second body to adhere this coating to the conductive element carried by the first body.
