Before the advent of PCBs, circuits were composed of point-to-point wiring. This method has low reliability because as the circuit ages, wire breakage can lead to open or short circuits at the wire nodes. Wire-wrapping technology is a significant advancement in circuit technology, as this method enhances the durability and replaceability of the wires by wrapping small diameter wires around the posts of connection points. As the electronics industry evolved from vacuum tubes and relays to silicon semiconductors and integrated circuits, the size and Price of electronic components also decreased. Electronic products have increasingly appeared in the consumer sector, prompting manufacturers to seek smaller and more cost-effective solutions. Thus, PCBs were born.
PCB manufacturing process
The production of PCBs is very complex. Taking a four-layer printed circuit board as an example, the manufacturing process mainly includes PCB layout, core board production, inner layer PCB layout transfer, core board drilling and inspection, lamination, drilling, chemical copper deposition on hole walls, outer layer PCB layout transfer, and outer layer PCB etching.
