Classification basis of circuit boards

1, single panel. The structure of the single panel is relatively simple and the price is relatively favorable. It has strict restrictions on the design of the circuit. In addition, the wires of the circuit board are concentrated on one side, and the wirings cannot cross each other, mainly applied to The early circuit can't be applied to more complicated products.

2, double panel. There are wiring on both sides of this board. It can pass through the vias to clear the lines between the two layers, so that a certain network connection can be formed. Its area is larger than that of a single panel. When wiring, it can be interlaced and can be wound around. On the other side, it is more suitable for more complex circuits. The double panel is a continuation of the single panel. When single-panel wiring is not enough, you need to use a double panel.

3. Multilayer board. Refers to a circuit board composed of three or more conductive pattern layers and insulating materials. It is mainly used for relatively complicated circuits, can be arranged in a multi-layer structure, and can be pressed together and between layers There are holes that are connected to each other. It uses multiple pieces of double-sided panels, which can increase the area of the wiring. The number of layers of the multi-layer board is generally even, and most of the boards are 4-8 layers.
