Aluminum  PCB Board

With over 10 years of profession PCB field experience, Shenzhen Tianweisheng Electronic Co., Ltd. speeds up R&D on major types.

For high-density PCBs, Shenzhen Tianweisheng Electronic Co., Ltd. could build max 30 layers rigid PCBs or 20 layers rigid-flex PCBs. The Max board thickness could achieve 8mm, aspect ratio is 16:1, the min. line width / space is 3 mil, also impedance controlled. So that to ensure the signal transmits smoothly.
