Computers have computer circuit boards, machines have machine circuit boards, and many electronic products need to be equipped with corresponding circuit boards. The pcb circuit board is also a kind of electronic product. I believe that a large part of my friends do not know what kind of product this is, and they also have doubts about it. So what is a pcb circuit board? What are the components of a pcb circuit board? Next, let's take a look at the relevant replies that Xiaobian brings to friends.

    PCB, the Chinese name is printed circuit board, is the support body of electronic components and the provider of electrical connection of electronic components. According to the number of circuit layers, it can be divided into single-sided, double-sided and multi-layered boards. Common multi-layer boards are generally 4-layer boards or 6-layer boards, and complex multi-layer boards can reach more than ten layers. At the same time that China has become a big country in the manufacture of electronic products, the global PCB production capacity is also shifting to China. Not only domestic-funded PCB manufacturing companies are accelerating their expansion of production capacity, but foreign-funded companies are also speeding up their transfer to China and adding new production capacity. Investment in the domestic PCB industry has always been hot. Industrial transfer has made China a big country in the PCB industry. The most important driving force comes from two aspects: cost and application industry chain. In terms of cost advantages, China has huge advantages in terms of labor, land, water and electricity, resources and policies; the vigorous development of downstream industries in China and the transfer of global machine manufacturing to China have provided huge market demand space. Due to the concentration of downstream industries and relatively low labor and land costs, China has become the region with the strongest development momentum. Printed circuit board, also known as printed circuit board, printed circuit board, referred to as printed board, English referred to as PCB, with insulating board as the base material, cut into a certain size, at least one conductive pattern is attached on it, and holes Such as component holes, fastening holes, metallized holes, etc.), which are used to replace the chassis of the previous electronic components and realize the interconnection between electronic components. Because such boards are made using electronic printing techniques, they are called "printed" circuit boards. It is inaccurate to call a "printed circuit board" a "printed circuit" because there are no "printed components" on the printed circuit board, but only wiring.
