Abstract
A computer program has been developed, which calculates any adjustable thin film resistor from simple input data (electrical, geometrical, positional, orientational), punched on “input cards”. The “output cards”, which contain the coordinates, are fed to a numerically controlled draughting machine, which produces either an intermediate ink-on-paper drawing or the final cut-and-strip artwork. Our CAD method proceeds in several steps, offering all the permitted solutions and providing for designer's options.
