Abstract

864,430. Hand-made negative for printed circuits. GENERAL ELECTRIC CO. Ltd., COLE, W. P., and McKEE, G. M. Oct. 20, 1958 [Oct. 23, 1958], No. 33940/58. Class 98(2) [Also in Groups XV and XXXVI] In the formation of a printed circuit by a photo-etch process (see Groups XV and XXXVI), the working negative 1 is made by laying out a representation of the conductive pattern, by means of black tape or Indian ink, on both sides of a transluscent Bristol board, four times as large on each dimension as the finished circuit board. Both sides of the board are then photographed on to separate plates, the master negatives thus formed being used to contact print master positives on to normal plastic base film. Each master positive is used to contact print a working negative formed from a sheet of polymethyl methacrylate coated on one side with a high contrast photographic emulsion.
