What is pcb, circuit board, pc board?

The English name of PCB is printed circuit board, 1 oz vs 2 oz which is directly translated into Chinese as Printed Circuit Board, and is referred to as "PCB". Some people call it "PC board" in Chinese and English, but it actually has another English name "PWB (Printed Wireborn), printed circuit board".

It should be noted that the manufacture of printed circuit boards is actually modeled on the printing technology of books and paper, which is done by projecting light through a thin film onto a negative film, and then chemically etching the copper foil circuit onto a piece of cardboard. However, with the development of technology, the manufacture of printed circuit boards has become more and more complex, but the printing process technology and operation still exist.
