PCB technology is based on the principle of circuit boards, using conductive materials to form circuits on non-conductive materials, making the interconnection between electronic devices easy and convenient. Generally includes the following aspects:
1. The manufacturing technology of PCB is to form circuits by chemically or physically processing single-layer or multi-layer thin non-conductive materials with appropriate metal thin films, achieving comprehensive optimization of electrical, mechanical, and spatial forms;
2. The electronic design technology of PCB includes circuits, integrated circuits, packaging, communication, microprocessing, embedded systems and other fields, and is an important component of digital, analog, power, and electromagnetic compatibility design technology;
3. PCB technology has achieved seamless quality control in various stages such as device packaging and printing, circuit copper foil and penetration sponge chemical processing etching, assembly, and testing, in order to achieve comprehensive optimization of product performance, signal transmission, and mechanical reliability.
(1) Printed circuit board design: Based on the circuit schematic, draw the pattern of the circuit board;
(2) Manufacturing circuit boards: Implementing circuit board patterns onto real circuit boards, including copper foil etching, printing drilling, warning openings, coating with anti-corrosion layers, and final shape adjustment;
(3) Circuit testing and repair: After the circuit board is manufactured, functional testing and troubleshooting are carried out. For defective circuit boards, they need to be repaired until they work properly.
PCB is widely used in various fields such as communication circuit boards, computer hardware, automotive electronics, aerospace, medical equipment, consumer electronics products, security inspection equipment, etc. Taking the electronic product industry as an example, PCB technology is widely used in fields such as mobile phones, tablets, televisions, computers, accessories, etc. Among them, the most important application of mobile phones and tablets is multi-layer PCB.
Uniwell Circuits is a multi-layer PCB manufacturer, capable of manufacturing up to 52 layers of high-precision PCB circuit boards.
