The history of Printed Circuit Boards (PCBs) can be traced back to the early 20th century. The earliest concept of PCBs was proposed by Austrian engineer Charles Ducas in 1920, who introduced the idea of using conductive ink to print brass wires on a substrate. However, the true birth of PCBs occurred in 1925 when Charles Ducas, in the United States, printed circuit patterns on an insulating substrate and established conductors through electroplating.

In 1936, Paul Eisler, an Austrian, first adopted PCB technology in radio devices. Subsequently, this technology was widely used in military radios by Americans in 1943. In 1947, the Federal Aviation Agency and the American Standards Association hosted the first technical symposium on PCBs, marking the official recognition and development of PCB technology.

Entering the 1970s, multilayer PCBs rapidly developed and continuously evolved towards high precision, high density, fine lines and small holes, high reliability, low cost, and automated continuous production. In 1956, China began researching and developing PCBs. With the introduction of foreign technology and the entry of foreign-funded enterprises, China became the world's largest PCB production base in 2006.

From early single-sided boards to modern multilayer boards, PCB technology has undergone significant evolution. Modern PCB technology is not only applied in military, communication, medical, and other fields but also plays a crucial role in the miniaturization and complexity of consumer electronic products.
