Abstract

1,084,074. Printed circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 3, 1965 [March 4, 1964], No. 9009/65. Heading H1R. [Also in Division G2] Printed circuits may be produced on irregular or inaccessible surfaces by the following photographic technique. As shown, a lighttransmitting cylindrical block 22 on which roughened image areas 23 are produced by scribing or sandblasting is fitted into a hollow cylinder 21 of non-conductive material coated on the inner wall 20 with a conductive metal layer and a photoresist. This assembly is now exposed to light source 25 so that light is totally internally reflected at the smooth background areas but is scattered on to the photosensitive material at the roughened areas 23. The block is removed, the photoresist is developed and the underlying metal is etched to leave the printed circuit. This technique may also be used for non-planar surfaces by placing the photosensitive material on such a surface and moulding a light-transmitting block bearing the roughened image to the requisite shape.
