Our dedication to excellence ensures that your innovations are in good hands.

What is a multilayer PCB?

It is a PCB made with three or more conductive copper layers. The conductive foil appears to be various layers of a multi-sided circuit board. The different inner layers are processed in pairs (on a core) and then bonded together using prepreg as the insulating layer. The layers are then placed in such a way that both sides of the PCB can be used to mount components with additional tracking/electrical connections on the inside of the board. Vias are used as a source of the electrical connections between the different layers of a multilayer PCB.

Many products use multilayer PCBs, including computers, medical equipment, in-car systems, GPS and satellite systems, industrial control systems
