Multi-layer PCB circuit board Manufacturers

Photoelectric boards refer to PCBs used for LCD and other purposes, and have very strict requirements on size.

There are three methods of resist coating: liquid resist coating method and FPC resist coating method for circuit board

PCB manufacturers mainly shoulder the important responsibility of printed circuit board. In view of the essential difference between this product and common items, when the circuit is too complex, the accuracy can be enhanced by printing, and the probability of missing the details of the circuit board will be reduced. Customers who are ready to implement printing tasks and purchase work will be put on the agenda as soon as possible when dealing with the manufacturer. After several rounds of communication and exchanges, the cooperation intention can be confirmed. During this period, the characteristics of the manufacturer should be explored in depth.

A chip refers to a silicon chip containing integrated circuits, which is small in size and is a part of a mobile phone, computer, or other electronic device. If the most important organ of the human body is the brain, then chips are the "brain" of electronic devices. A chip is an integrated circuit, also known as a microelectronic chip, composed of many electronic devices, circuit components, organic matter, etc., packaged on a single silicon chip, and is one of the foundations of modern electronic technology. Because of its small size, low power consumption, high manufacturing difficulty, and high reliability

A semiconductor is a substance with a conductivity between that of a conductor and an insulator. It is not very conductive in a pure state, but its conductivity can be adjusted by adding impurities (doping) or changing the temperature. The typical representative of semiconductors is silicon, which is widely used in the manufacturing of electronic components. Semiconductor technology is the cornerstone of modern electronic devices, such as smartphones, computers, digital cameras, etc., all rely on semiconductor chips. In addition, semiconductors are also very important in the energy field, such as semiconductor materials, which are the core of solar cells

Substances and materials in nature can be divided into three categories: conductors, semiconductors and insulators according to their conductivity. The resistivity of semiconductor is in the range of 1m Ω· cm ~ 1g Ω· cm (the upper limit is taken according to Xie jiakui's electronic circuit, and 1/10 or 10 times of it; because the angle mark is not available, the current description is used temporarily)
