The multilayer PCB refers to a printed circuit board with more than two layers, which is composed of interconnected lines on several layers of insulating substrates and pads for assembling and soldering electronic components. It has the function of conducting each layer of lines and insulating each other. High-speed PCBs are generally designed with multilayer PCB. Common multilayer boards are generally 4-layer boards or 6-layer boards, and complex multi-layer boardscan reach dozens of layers.
