Before the advent of printed circuit boards, the interconnection between electronic components relied on the direct connection of wires to form a complete circuit. In modern times, the circuit panel 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 production costs, people began to delve into the method of replacing wiring with printing. Over the past 30 years, engineers have repeatedly proposed to use metal conductors for wiring on insulated substrates. The most successful was in 1925, Charles Ducas of the United States printed circuit patterns on an insulating substrate, and then used electroplating to successfully establish conductors for wiring.

In the past ten years, my country's printed circuit board (PCB) manufacturing industry has developed rapidly, and its total output value and total output have both ranked first in the world. Due to the rapid development of electronic products, price wars have changed the structure of the supply chain. China has both industrial distribution, cost and market advantages, and has become the world's most important printed circuit board production base.

Printed circuit boards have developed from single-layer to double-sided, multi-layer and flexible boards, and continue to develop in the direction of high precision, high density and high reliability. Continuously shrinking volume, reducing costs, and improving performance have enabled printed circuit boards to maintain strong vitality in the development of electronic products in the future.

The future development trend of printed circuit board manufacturing technology is to develop in the direction of high density, high precision, fine aperture, fine wire, small pitch, high reliability, multilayer, high-speed transmission, light weight, and thinness in performance.
