PCB circuit board is one of the components in the electronic industry, mainly an important electronic component inside the circuit board circuit. Do you know the function of a PCB circuit board? Let's take a look together below!
PCB is the support body for printed electronic components, mainly providing electrical connections. Because the PCB circuit board is made using electronic printing technology, it is also called a "printed" circuit board. So what is the function and function of a PCB circuit board? Let's continue to take a look below.
The PCB circuit board plays a significant role in providing mechanical support for various electronic components and assemblies, such as integrated circuits, by fixing solder pads; In addition, it is wiring, which is the electrical connection we mentioned above, and can also provide the electrical characteristics required in electronic devices, such as characteristic impedance, etc; The third one is to provide solder mask patterns in electronic devices, such as green oil and silk screen, which can recognize characters and graphics.
So are there many types of PCB circuit boards? If classified according to the number of circuit layers, there are still three types of PCB circuit boards, namely single panel, double-sided board, and multi-layer board. Of course, the commonly used PCB boards are usually 4 or 6 layers, and complex ones can also have dozens of layers. Generally, a single panel is a basic PCB with only one side, which has been largely phased out now because the parts are concentrated on one side and the wires are on the other side, with many strict restrictions; Double sided panels have wiring on both sides and a larger area than single panels, making them more suitable for complex circuits; Multilayer boards use more single or double-sided wiring boards, which can increase the wiring area. However, due to the use of large supercomputers nowadays, super multilayer boards are gradually no longer being used.
The above is some content about circuit boards. It can be said that the development of PCB circuit boards is also constantly improving. Nowadays, circuit boards are constantly shrinking in size, reducing costs, and improving their performance. China has also become an important global production base for printed circuit boards. In the future, PCB circuit boards will also develop towards greater precision, and we can still look forward to it!
