Printed circuit board - Wikipedia

Printed circuit boards were introduced to reduce the size, weight, and cost of parts of the circuitry. In 1960, a small consumer radio receiver might be built with all its circuitry on one circuit board, but a TV set would probably contain one or more circuit boards.

Printed Circuit Board Fabrication - Etching Outer Layer

This is because of the “puddling” effect of the etchant on the top of the printed circuit board. The top side of a printed circuit board panel builds up a thick puddle of etchant, that absorbs the energy of the sprays, and makes replenishment of the etchant at the surface of the metal a …

The History of Printed Circuit Boards - Mint Tek Circuits

For prototypes, or small production runs, wire wrap or turret board can be more efficient. Predating the printed circuit invention, and similar in spirit, was John Sargrove‘s 1936–1947 Electronic Circuit Making Equipment (ECME) which sprayed metal onto a Bakelite plastic board. The ECME could produce 3 radios per minute.
