Prototype to Production PCBA with Seamless Scaling Support

SZH operate a fully self-owned production base equipped with multiple high-precision SMT lines, complemented by DIP, testing, and assembly lines. This enables flexible production from prototyping to large-scale PCB assembly.
High-Precision SMT Lines: Support 01005 components, 0.3mm pitch BGA, QFN, and other fine-pitch package assembly.
Full-Process Coverage: Including double-sided SMT, mixed assembly, selective soldering, and press-fit technology.
Rigorous Quality Control: Full-process inspection with SPI, AOI, X-Ray, functional testing, and aging test systems.
