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.

  • Layers up to 36

  • Quick turn & no MOQ

  • AOI inspection

  • Free 100% electrical test before shipment

Multi-layers PCB

With the rapid development of technology, there is a great demand for advanced PCBs. Now the advanced PCB has been widely used in high-end and high-precision electronic devices, such as automotive electronics, complex industrial equipment, complex computing, instrumentation, as well as communication equipment, etc. So multi-layers PCB design is becoming popular. Runrays have robust manufacturing capabilities of deliver 2-36 layers PCB according to customer design files.
