Short Cuts in Printed-Circuit Wiring

The purpose of this paper is to illustrate the responsibilities of product engineering and design in evolving printed wire products. The short cuts are the results of planning with maximum standardization. The products to be used for illustration are 23 servo-amplifier designs used in military airborne equipment. The quantity of amplifiers to be produced is not large and might be classified as a short-run type production. Printed wiring was decided upon on the basis of reduced unit cost and consistency of amplifier performance. It is important to point out that the products mentioned are part of a large system within a large company. Many of the principles illustrated herein are necessary because of the great coordination a large program requires.
