How to identify multilayer pcb? | |
Multilayer printed circuit boards and double-sided PCB boards are similar in appearance. Ordinary people can’t see the difference between them without paying attention, or you can’t tell whether it is a double-sided PCB board or multilayer PCB board. So, how to distinguish between ordinary double-sided PCB boards and multi-layer PCB boards? First of all, we must have an understanding of the number of layers of the circuit board. The number of layers of the PCB board is the inner layer. 1 layer is referred to as single layer PCB, and 2 layers is referred to as double sided PCB. Multilayer PCB board refers to 4-48 layers; the higher the number of layers, the higher the unit price. Because the inner layer of the circuit is to be pressed, the technical content is high, and the machine cost is relatively high. Generally speaking, you can identify multilayer pcb by following: The more layers, the larger the shadow in the sheet; Dim shadows can be seen in the multi-layer PCB circuit board, if the shadow is light then you can see a little dim, and if the shadow is deep you can see the circuit clearly; Multilayer PCB circuit boards generally have a smooth surface, especially when they are cleaned after forming and processing; If you want to know how many layers of the PCB board are, and the precise data, you can only check through the IM inspection of the manufacturer or the PCB drawing of the development engineer.  | |
