Professional Custom PCBA Loaded PCB Assembly
SZH has its own fully self-contained production plant with several high-precision SMT lines at the core, and additionally DIP, testing, and assembly lines. Thus, they can provide flexible manufacturing from prototype up to mass PCB assembly.
High-Precision SMT Lines: Able to mount 01005 components, 0.3mm pitch BGA, QFN, and other fine-pitch packages.
Complete Process Coverage: SMT double-sided, mixed assembly, selective soldering, and press-fit technology are all included.
Strict Quality Control: Inspection throughout the whole process with SPI, AOI, X-Ray, functional testing, and aging test systems.
