MULTIPLANE CIRCUIT BOARD AND METHOD OF PRODUCING SAID BOARD

摘要

The specification describes a method of producing multiplane circuits of the type utilized in printed circuit boards and the boards produced according to the method. The present invention permits the production or manufacture of multiplane circuit boards without requiring the preparation of specific different conductor track diagrams or drawings for different multiplane circuits. The method makes use of premanufactured units which are used for all circuit boards produced thereafter. Depending on the complexity of the multiplane circuit to be produced use is made of one or a plurality of semi-finished units which may be press-molded to form one circuit board.
