Background

Printed circuit boards, also known as printed circuit boards (pcbs), often referred to by the acronym pcb (printed circuit board), are important electronic components, support for electronic components, and providers for connecting electronic components and circuits. It is called a "printed" circuit board because it is made using electronic printing techniques. Before the advent of printed circuit boards, interconnections between electronic components were completed by direct wire connections. Circuit panels are now only available as effective experimental tools, and printed circuit boards have become an absolutely dominant position in the electronics industry. In the beginning of the 20 th century, in order to simplify the fabrication of electronic devices, reduce the number of wirings between electronic components, and reduce the fabrication cost, efforts have been made to replace the wiring method by printing. Over thirty years, engineers have proposed to use metal conductors as wiring on insulated substrates. In 1925, Charles Ducas in the united states printed a circuit pattern on an insulating substrate, and then successfully formed conductors for wiring by electroplating.
