HASL ENIG OSP PCB Assembly Service FR4 Multilayer Printed Circuit Board Assembly For Outdoor Large Screen Control

General Introduction of Multilayer PCB

As the name suggests, a multi-layer circuit board can only be called a multi-layer circuit board with more than two layers, such as four layers, six layers, eight layers, and so on. Of course, some designs are three-layer or five-layer circuit, also called multi-layer PCB circuit board.

Conductive wiring diagram larger than the two-layer board. The insulating substrate is separated between the layers. After each layer of the circuit is printed, each layer of the circuit is overlapped by pressing. After drilling, the electrical connection between them is usually achieved through plated through holes on the cross section of the circuit board.
