BCM56852A2KFSBLG Manufacturers

The rise of 5g has driven the innovation, creation and rapid development of the global 3C industry. When more iterations of terminal products become very frequent and rapid, the common development of all core enterprises in the industrial chain becomes very important. 3C products focus on the quality effect and service life. Therefore, the parts and components in the products are very important. As one of the indispensable suppliers in the industrial chain, the buyer is also cautious in choosing.

Semiconductor is the foundation of modern electronic technology, and its development can be traced back to the late 19th century. This article will introduce the development history of semiconductors and explore their importance to modern technology.

PCB (printed circuit board), whose Chinese name is printed circuit board, is one of the important components in the electronic industry. Almost every kind of electronic equipment, from electronic watches and calculators to computers,

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.

The semiconductor support industry mainly includes semiconductor materials, semiconductor equipment and semiconductor software services:

According to the number of layers, there are three types of single-sided, double-sided, and multi-layer circuit boards, which are distinguished according to the circuit layers inside.
