Materials for printed circuits and wiring

A brief résumé of the printed-circuit techniques in use and an outline of the preparation of the metal-clad insulating board are given. A detailed description of the types of material available is included and the performances of these materials in varying conditions are compared. Comparative costs and an outline of the fields of applications of the varying types of materials are discussed. The paper concludes with an outline of possible future trends in the production of printed-circuit materials.
