Abstract

1,262,245. Printed circuits. INTERNATIONAL BUSINESS MACHINES CORP. 20 March, 1970 [2 April, 1969], No. 13673/70. Heading H1R. A substrate; 10, is coated with a conducting layer, 11, on which areas 13 of spacing material are formed, the intervening spaces 14 then being built up with conducting material to form conductors, the areas 13 and the conducting layer beneath being then removed and replaced by an insulator in liquid or powder form, which is then hardened in. position at 16, any excess covering the conductors being subsequently removed. The substrate may be of epoxy resin ceramic or steel of high impedance, the areas 13 being provided by applying and. exposing a photo-resist. The conductors may be built up electrolytically, the areas 13 being removed with a solvent, and the portions of the layer 11 beneath by etching. The insulator applied between the conductors may be of resin or powdered glass which is sintered. The finished board may be used as the substrate for a subsequent layer of a multilayer board.
