Why Choose Multi-Layer Design in PCB Boards?
As we all know, multilayer PCB design service boards are recommended for high-speed PCB boards. But why is that? This blog tells you the reasons. First, the multilayer panel distributes the inner layer exclusively for energy and ground. Therefore, it has the following advantages: 1. The power supply is very stable; 2. The circuit impedance is greatly reduced; 3. The wiring length is greatly shortened. In addition, from a cost perspective based on the same area, the cost of a multi-layer circuit board is higher than the cost of a single-layer circuit board. But considering other factors such as circuit board minimization and noise reduction comfort, the cost difference between a multi-layer circuit board and a single-layer board is not as high as we expected. see more about automobile electrical system
According to the data we know, the observations conclude that the same circuit is designed. If the area of a four-layer board can be reduced to half of the layer board, the cost is the same as the cost of the second-layer board. Although the multi-layer batch will affect the unit cost of the board, but there is no price difference 4 times. If there is more than 4 times the price difference, you can reduce the cost to 1/4 of the double-layer board as long as you can try to reduce the board space. For this reason high-speed panels require multi-layer panels.
