The strengths behind your build
Engineering depth.
Manufacturing confidence.
- 01
Engineering support before production
Our 20+ R&D engineers support design optimization, DFMA review and product validation. Resolve manufacturability questions before the build moves to the line.
- 02
One partner, from components to finished product
Connect PCB manufacturing, sourcing, SMT, DIP, final assembly and testing. Coordinate single and multi-layer boards, pilot runs and repeat production without separate handoffs at every stage.
- 03
Quality records you can trace
Inspection resources include SPI, AOI, X-ray and custom ICT/FCT. MES connects production progress with inspection records, giving your team a clearer view of build status and quality evidence.
- 04
China and Thailand, working together
