The Austrian engineer Paul Eisler invented the first printed circuit which became commonplace commercially in the 1950’s.Today just about every electronic appliance contains a printed circuit board. The invention of the PBC has helped to enable electronic circuits to be more compact and convenient.
The PBC board is either made from fiberglass with a copper foil bonded on to one or both sides or paper reinforced phenolic resin with bonded copper foil. The latter is less expensive and can be found in most household appliances. A thin layer of tin-lead can also be found in PBC’s which prevents oxidation and also nickel and gold which enhances conductivity.
