PCBA materials mainly involve electronic components, printed circuit boards, also known as printed circuit boards, printed circuit boards. The English abbreviation PCB (Printed circuit board) is often used. Is a provider of electronic component circuit connection. Because it is made using electronic printing technology, it is called a "printed" circuit board.

Before the advent of printed circuit boards, the interconnection between electronic components relied on direct connection of wires to form a complete circuit. Now, the circuit breadboard only exists as an effective experimental tool, and the printed circuit board has become an absolute dominant position in the electronics industry. At the beginning of the 20th century, in order to simplify the production of electronic equipment, reduce the wiring between electronic parts and reduce the manufacturing cost, they began to study the method of replacing wiring by printing.

In the past thirty years, engineers have continuously proposed to add metal conductors to the insulated substrates for wiring. The most successful is that in 1925, Charles Ducas of the United States printed a circuit answer pattern on an insulated substrate, and then successfully established a conductor for wiring by electroplating.
