At present, the common PCB board materials on the market are mainly insulating materials, metal copper and solder. Moreover, our common PCB boards can be divided into three types of single-sided PCB boards, double-sided PCB boards and multi-layer PCB boards. See specific introduction below:
At present, the common PCB board materials on the market are mainly insulating materials, metal copper and solder. Moreover, our common PCB boards can be divided into three types of single-sided PCB boards, double-sided PCB boards and multi-layer PCB boards. See specific introduction below:
1. single-sided PCB board
Single-sided PCB board mainly refers to one side of the copper, the other side is not coated with copper PCB. Single-sided PCB board can only be placed on the copper side of the components (hereinafter referred to as components) and wiring, suitable for simple circuits.
2. double-sided PCB board
The double-sided PCB board includes two layers of top layer (Top Layer) and bottom layer (Bottom Layer), with copper on both sides and an insulating layer in the middle. Both sides can be wired and generally need to be connected by vias or pads. The double-sided PCB board can be used for more complex circuits and is an ideal PCB board.
3. multilayer PCB board
Multi-layer PCB board generally refers to more than three layers of PCB board. It adds an internal power supply layer, a ground layer and a plurality of intermediate signal layers on the basis of a double-sided PCB board. With the rapid development of electronic technology, the integration of circuits is getting higher and higher, and the application of multi-layer PCB boards is becoming more and more extensive. However, due to the increase in the number of layers of the multi-layer PCB board, the processing process is difficult, and the production cost is also high.
Therefore, when we make the circuit board, we should make it according to our own needs, so that the stability of the circuit board can be high.
