Multilayer Circuit Board Custom Pcba Electronic Printed Circuit Board Factory

Multilayer Circuit Board

Double Sided PCB is the middle layer of medium, and both sides are wiring layers. Multilayer PCB is a multi-layer wiring layer. Between every two layers is a dielectric layer. The dielectric layer can be made very thin. Multilayer PCB has at least three conductive layers, two of which are on the outer surface, and the remaining layer is integrated into the insulating board. The electrical connection between them is usually achieved through plated through holes on the cross section of the circuit board.

The distinction of Multilayer PCB

The circuit board determines the process difficulty and processing price according to the number of wiring surfaces. Common circuit boards are divided into single-sided wiring and double-sided wiring, commonly known as Double Sided PCB and Double Sided PCB. However, high-end electronic products are restricted by product space design factors. In addition to surface wiring, multiple layers of circuits can be superimposed inside. During the production process, after each layer of wiring is made, it is positioned and pressed by optical equipment to superimpose the multilayer circuits on a circuit board. Commonly known as Multilayer PCB. Any circuit board with more than or equal to 2 layers can be called Multilayer PCB. Multilayer PCB can be divided into Multilayer Rigid PCB, Multilayer Flexible PCB, Multilayer Rigid-flex PCB.
