PCB circuit board layer number more better?
PCB board, translated as printed circuit board, it can be viewed as a miniature bearing platform, also is an important carrier of integrated circuit. It’s appearance from one side to two sides to multiple layers allows the limited space to accommodate as many more complex lines as much as possible. So a lot of friends think: the more layers of the circuit board will the better, the better the performance. So today we're going to talk about the validity of that statement.
Currently, the most common PCB multilayer board in the market has four and six layers, depending on the customer's product requirements. The higher the precision required by the product, the higher the requirements for the number of layers on the PCB board. Such as medical, military, aerospace and other equipment.
The more layers of PCB, The degree of difficulty in the process will also increase. The multilayer PCB are designed to provide more space for electronic circuits, so this does not mean that multilayer PCB are more functional than those with fewer layers. PCB board has a kind of electromagnetic interference problem, and the multilayer board can effectively reduce this problem, so that the service life of PCB board increases.
In the PCB industry, the number of layers is only a rigid requirement in the design of the circuit board. In fact, the commonly used four and six layers of boards also need many excellent performance. Therefore, in terms of functionality, the number of layers and the number of layers cannot be compared and the quality of PCB board cannot be judged by this standard.
To sum up, PCB board is not the more layers, the better its function, but to combine its need to use PCB board product requirements to determine to design .For more information please contact us 15696407315
