Manufacture of dielectric substrate

Abstract

Abstract PURPOSE: To easily form holes with the desired shape at arbitrary locations, by making up the holes to a green sheet by means of a jig, by buring the sheet, by inserting metallic blocks into the holes and by sticking the sheet fast to a substrate by means of press. CONSTITUTION: A green sheet GS is built up, holes P with the desired shape are formed at the arbitrary locations by employing a jig, the sheet GS is fired, the metallic blocks 2 of copper, aluminum, etc. are inserted into the holes P of a substrate 1, the blocks 2 are welded to the substrate 1 by means of press and the projecting blocks 2 are removed by means of an edge tool 7. The holes with the desired form can easily be made up at arbitrary positions by working the holes in a green sheet stage. COPYRIGHT: (C)1980,JPO&Japio
