Abstract

893,479. Printed circuits. PYE Ltd. July 28, 1958 [Aug. 6, 1957], No. 24773/57. Class 37. A method of manufacturing a printed circuit board consists of forming the conductors on one side of the board, and applying a layer of insulating material, e.g. an epoxy resin, over the whole surface of the board by a silk screen technique, except in those places to which it is required to solder components to the circuit.
