Manufacturing services
Electronics manufacturing services, end to end
From pre-production engineering through final box build, SUNKING EMS supports each stage of your electronics program from our Shenzhen facility.
Board assembly
SMT, PCBA, and through-hole
SMT assembly
High-speed surface-mount placement and reflow on our SMT lines, with automated optical and solder inspection of finished boards.
PCBA
Complete printed circuit board assembly, combining SMT and through-hole work into finished, tested board assemblies.
Through-hole soldering
Manual and wave-soldering for connectors, power components, and mechanical parts that require through-hole joints.
Test and supply
Testing, programming, and sourcing
ICT and FCT testing
In-circuit testing checks component placement and solder joints, while functional testing confirms each board performs to its specification.
Programming
Firmware flashing and device programming, handled to your specified image and verified against the build record.
Component sourcing
Sourcing of electronic components through approved channels, with BOM review to reduce lead-time and availability risk.
Integration and engineering
Box build, NPI, and DFM support
Box build brings boards, cables, and mechanical parts together into a finished enclosure, packaged to your requirements. Before production starts, our NPI and DFM reviews check your design for manufacturability, component availability, and test coverage.
Each project begins with an engineering review, so issues are raised early rather than discovered on the production line.
