Abstract :
The present position in the development and use of printed circuits is discussed and some schemes for depositing resistors as part of a printed wiring process are mentioned. A description is given of a pilot-production process used for digital-computor circuits. The subdivision of the size of units by circuit functions is suggested to have an optimum value lying between two uneconomic extremes. Characteristics of potting resins are discussed, the results of experimental work on loaded resins are tabulated and the results of measurements made on printed and potted coils are given. The application of potted-circuit techniques to a telemetering unit and an experimental radar equipment is shown. Possible future automatic assembly techniques are discussed and illustrated by means of a flow diagram.
