Multi-Layers PCB Fabrication
PCBBOX can offer multi-layers PCB with excellent quality and cost efficiency. The number of layers is up to 36, which can meet needs with complex design and for compact devices. Basically, a multilayer PCB has three or more layers of copper foil, insulated from each other by lamination or coating, and joined together to form a single piece. The outer layers are usually single-sided PCBs, while the inner layers are double-sided PCBs.
