Abstract

1,126,370. Printed circuits. BRITISH AIRCRAFT CORP. (OPERATING) Ltd. 21 March. 1967 [29 Dec., 1965], No. 55074/65. Heading H1R. In a multilayer or double-sided printed circuit, connection is made between conductors 4a. 4b which are separated by an insulating layer 56, by forming a hole in layer 56 where such connection is required, and forming the lower conductor 4a with a projecting portion 7 substantially the thickness of the layer 56; the layers are then assembled, and a welding electrode 8 is applied to the free surface of upper conductor 4b above the projecting portion 7 to form a welded joint 9. Conductors 4a, 4b are originally formed by photo-etching or electron beam scribing, and projecting portion 7 is preferably formed by selective etching, although an additive technique may alternatively be used. The multilayer circuit is built up progressively, welded joints being made where required at each level (Fig. 4, not shown). Fig. 1 (not shown) discloses a method of pinchwelding registering conductors within a hole in an intermediate insulating layer.
