PCB circuit board is one of the components of the electronic industry, which is mainly an important electronic component in the circuit board. So do you know what the role of the PCB circuit board is? Let's understand it together!

PCB is the support for printed electronic components, Primarily providing providers of electrical connections, Because the PCB's circuit board is made using electronic printing, So it is also called a "printed" circuit board. So what is the function and function of the PCB circuit board? Let's go on here.

Where The PCB circuit board is still very functional, Which can provide a role in pad fixation, Is to provide integrated circuit and other electronic components and assembly of mechanical support; The other is the line, That's what we call the electrical connections above, And can also provide the electrical characteristics required in the electronic equipment, Such as characteristic impedance and so on; The third is the ability to provide welding resistance graphics in electronic equipment, That is, green oil and screen marks, Can recognize the characters and the graphics.

So PCB board types? If it is based on the number of circuit layers, there are still three types of pcb circuit board, namely single panel, double panel and multilayer board. Of course, we are generally more commonly used pcb circuit board are 4 or 6 layers, complex also has dozens of layers. General single panel is the basic PCB, only one side, now basically eliminated, because the parts are concentrated on one side, the wire on the other side, there are many strict restrictions; double panel is both sides, and the area is larger than the single panel, the advantage is more suitable for complex circuit; multilayer board is using more single or double-sided wiring board, can increase the wiring area, but now there are many large supercomputer, so super multilayer board has gradually not been used.

This is some of the circuit board, It can be said that the development of PCB circuit board is also progressing, Now the circuit boards are also shrinking in size, reducing costs and improving their performance, And China has also become the world's important printed circuit board production base. The future PCB circuit board will also develop in a more precise direction, or you can look forward to it!
