The reason why PCB can be used more and more widely is because it has many unique advantages

Electronic components are components of electronic components and small machines and instruments. They are often composed of several parts and can be used in similar products; It often refers to some parts of electrical appliances, radios, meters and other industries, and is the general

Semiconductor has the following characteristics: dopability, thermal sensitivity, photosensitivity, negative resistivity temperature, and rectifiability.

Our common computer boards and cards are basically epoxy resin glass cloth based double-sided printed circuit boards. One side is the plug-in components, and the other side is the welding surface of the component feet. It can be seen that the welding points are very regular

FPC circuit board can be divided into single panel, double-sided board and multilayer board according to the number of circuit layers. The common multilayer board is generally 4-layer board or 6-layer board, and the complex multilayer board can reach dozens of layers.

There are many forms of matter, such as solid, liquid, gas, plasma and so on. We usually call materials with poor conductivity, such as coal, artificial crystal, amber, ceramics and so on, insulators. Metals with good conductivity, such as gold, silver, copper, iron, tin and aluminum, are called conductors. The material between conductor and insulator can be simply called semiconductor. Compared with conductors and insulators, the discovery of semiconductor materials is the latest. Until the 1930s, when the purification technology of materials was improved, the existence of semiconductors was really recognized by the academic community.
