PCB production process, which refers to the production process of printed circuit boards. Almost every electronic device, from electronic watches and calculators to computers, communication electronics, military weapon systems, as long as there are integrated circuits and other electronic components, printed circuit boards are used for electrical interconnection between them. In the research process of larger electronic products, the most fundamental success factors are the design, documentation, and manufacturing of the printed circuit board of the product. The design and manufacturing quality of printed circuit boards directly affect the quality and cost of the entire product, and even lead to the success or failure of commercial competition.
