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.
Boards are produced with inner-layer line width and spacing down to 3.0/3.0 mil, copper weights from 0.5 to 6.0 oz, aspect ratios up to 11:1, and board thicknesses from 0.2 mm to 8.0 mm on panels up to 18″ × 24″. Surface finishes include HASL, lead-free HASL, ENIG, immersion silver, and immersion tin, with solder mask and silkscreen in any color on request.
Quick-turn prototypes ship in as fast as 24 hours for 1–2 layer boards and 3–7 working days for multilayer designs, with no minimum order quantity — so you can validate a single board before committing to volume. Every board is electrically tested and AOI-inspected before shipment, and quotes are returned within 24 hours, 7 days a week.

We analyze your Gerber/ODB++ files for manufacturability before production starts.
Material & Imaging
Substrate preparation, inner-layer imaging and etching.
Lamination & Drilling
Layer lamination, mechanical/laser drilling for vias and holes.
Plating & Surface Finish
Copper plating plus your chosen surface treatment (ENIG, HASL, etc.).
Solder Mask & Silkscreen
Solder mask and legend printing in the color you specify.
E-Test & Inspection
Electrical test and visual/AOI inspection before shipment.
