PCB Fabrication Services in Shenzhen

Rigid · Flex · HDI · Impedance-controlled — up to 42 layers, with DFM and quick-turn prototyping.

BELI Technologies is a Shenzhen-based PCB fabricator producing rigid, flexible, HDI, and impedance-controlled boards up to 42 layers. Every order includes DFM (Design for Manufacturability) analysis to optimize your design for yield and cost before production begins.

BELI Technologies offers comprehensive PCB fabrication services supporting rigid PCB, flexible circuits, HDI, and impedance-controlled boards. Our state-of-the-art facility can produce boards from 1 to 42 layers using a wide range of materials including FR-4, Polyimide, Aluminum, Ceramic, and Rogers high-frequency substrates.

Our DFM (Design for Manufacturability) analysis ensures your boards are optimized for production before manufacturing begins, reducing costs and time-to-market.
