Surface Mount PCB Assembly

In surface mount PCB assembly, components are mounted directly on the PCB surface by automatic SMT machines. This assembly technique is applied in many applications such as Communications, Security, Computer, Medical, Industrial, Automotive electronics and Smart home fields. With 6 automated PCB assembly production lines, we are capable of assembling low volume PCBA prototype and high volume PCBA orders. We ensure consistent high quality and accurate placement of components with the use of the latest SMT technology. Our surface mount SMT PCB assemblies are known for their high mechanical strength, making them a reliable choice for high-speed circuit and de-coupling applications.

Advanced Equipment & Technology

We operate multiple high-speed pick-and-place machines capable of handling fine-pitch components such as 0201, 0402, QFN, and BGA with placement accuracy within ±0.02mm. Our stencil printers work in tandem with SPI (Solder Paste Inspection) equipment using 3D imaging to ensure consistent solder paste volume and precise deposition. Reflow ovens with multi-zone temperature control support lead-free profiles, while 100% AOI (Automated Optical Inspection) and X-ray inspection detect defects such as solder bridges, tombstoning, and hidden joint issues early in the process
