Abstract

1424663 Printed circuit masters PALMA ELECTRONICS Ltd 3 Jan 1973 [5 Jan 1972] 519/72 Heading G2X A printed circuit master pattern is prepared by selecting a starting pattern from a stock of such patterns and altering it (by additions or deletions) in fact or effect to provide said master. The different starting patterns in the stock are each in the form of a regularly repeating unit pattern and comprise a grid of mutually perpendicular intersecting lines, with enlarged areas representing pads at the intersections of at least some of the lines in some of the patterns, and with discrete areas representing pads located between grid lines in the remaining pattern(s). Composites of altered patterns may be made.
