Multilayer pcb circuit board

The name of multilayer printed circuit board is incredible it’s more than two layers of circuit board to be called multilayer, so multi-layer board is more than two layers, four layers, six layers, eight layers, and so on.Of course, some designs have three or five layers, also called multilayer.The conductive route diagram larger than the second layer plate, the insulation base material is separated between the layer and the layer. After each layer is printed, the wires of each layer are overlapped by pressing.After that, the hole is drilled again to realize the conduction between each layer of lines.

The advantage of the multi-layer printed circuit board is that the circuit can be distributed in the multi-layer inside wiring, so that more sophisticated products can be designed.Or smaller products can be made with multiple layers.Such as: medical security and industrial control equipment are widely used.In addition, multiple layers can increase the flexibility of the design, better control of differential impedance and single-end impedance, and better output of some signal frequencies.

The multi-layer printed circuit board can be used to make high-quality and efficient machines and high-precision electronic products. The cost will be no less. The double-side radiation can be connected to the front and back by perforation, and it can also be used as a plug-in.The multi-layer board is made of copper on both sides of the board.

The multi-layer printed circuit board (PCB) is the inevitable result of the development of electronic technology towards high speed, multi-function, large capacity and small volume.With the continuous development of electronic technology, especially the extensive and in-depth application of large-scale and ultra-large-scale integrated circuits, it is rapidly developing into the direction of high density, high precision and high number. Its technology of fine lines, small hole penetration and high plate thick hole ratio of blind hole is used to meet most of the current market needs.
