Computer has computer circuit board, machine has machine circuit board, a lot of electronic products are required to be equipped with the corresponding circuit board. PCB circuit board is also a kind of electronic products, I believe that a large part of friends do not know what kind of product this is, it also has doubts. So what exactly is a PCB? What are the components of the PCB? Next, let\'s take a look at the relevant replies brought by xiaobian for friends.
What is a ? How much do you know about the composition of PCB?

What is a PCB?
PCB, the Chinese name is printed circuit board, is the support body of electronic components, is the supplier of electrical connection of electronic components. According to the number of circuit layers can be divided into single panel, double panel and multi-layer board. Common multilayer board is 4 layer board or 6 layer board commonly, complex multilayer board can reach more than 10 layers. As China becomes a major electronic product manufacturing country, the global PCB production capacity is also shifting to China. Not only domestic PCB manufacturing enterprises are accelerating the expansion of production capacity, but also foreign enterprises are accelerating the transfer and new production capacity to China. The domestic PCB industry investment is always hot. The most important driving force for industrial transfer to become a PCB industry power in China comes from two aspects: cost and application industry chain. In terms of cost advantages, China has huge advantages in labor, land, hydropower, resources and policies. Downstream industry in China's vigorous development, global machine manufacturing transfer to China, providing a huge market demand space. China is the region with the strongest development momentum due to the concentration of downstream industries and relatively low labor and land costs. Printed circuit board, also known as printed circuit boards, printed circuit board, or PCB, English abbreviation PCB, insulation board as base material, cut into a certain size, with at least one conductive graphics, and cloth have a hole (such as component hole, fastening hole, hole metallization, etc.), is used to replace previous device electronic components of the chassis, and realize the connection between the electronic components. Because this board is made by electronic printing, it is called "printed" circuit board. The customary term "printed circuit board" as "printed circuit" is inaccurate, since there are no "printed components" on a printed board, only wiring.
