The History of Printed Circuit Board

Jul 22, 2017

In the early twentieth century, in order to simplify the manufacture of electronic machines, reduce the wiring between electronic parts and reduce the cost of production, they began to study the ways of replacing the wiring by printing. For thirty years, engineers have proposed to use metal conductors for wiring on insulated substrates. The most successful trying was in 1925, when the Charles Ducas printed circuit patterns on insulated substrates and successfully built conductors for wiring.

Until 1936, the Austrian Paul Eisler (Paul Eisler) published a foil membrane technology in the UK, he used the Printed Circuit Board in a radio device; while in Japan, Miyamoto Yoshinosuke by spraying method "and her graduate studies wiring method, blowing wiring method (Patent No. 119384)" successful patent applications.
