Our SMT Assembly Service Process
As a professional SMT assembly service provider, we follow a rigorous process to ensure each PCB is assembled efficiently, accurately, and reliably. Our core service process includes: 1. Precision Solder Paste Printing- Using high-precision stencil printers, solder paste is evenly applied to PCB pads, ensuring accurate solder placement and providing a solid foundation for reliable soldering.
- Advanced automatic pick-and-place machines (e.g., Yamaha, Siemens) rapidly and accurately place various components such as ICs, resistors, and capacitors, supporting fine-pitch components and high-density layouts.
- Reflow ovens with nitrogen protection precisely control the temperature profile, melting the solder paste to form strong solder joints, ensuring long-term reliability.
- Eco-friendly cleaning processes remove residues, improving electrical performance and board appearance, while complying with industry environmental standards.
- AOI (Automated Optical Inspection) and X-Ray inspection check solder joints, component placement, polarity, and more. Combined with manual verification, this ensures zero defects.
- Functional testing (ICT/FCT) validates circuit performance and simulates real-world usage, identifying potential issues before shipment.
- Professional engineers quickly locate and fix any detected issues, ensuring the final yield meets quality standards.

What are some trends in SMT assembly?
The assembled PCBs that were delivered worked flawlessly. The component placement is excellent. Mis wang, the Suga engineer in charge of our project, and I hit it off right away. She asked pertinent questions to ensure that the project was properly completed. We had a very nice, short, and to-the-point conversation.
This board is required to charge my robotic platform's lipo batteries (rover). First-time order with excellent communication throughout the ordering process, manufacturing progress, and tracking up to delivery. Very good price, especially for the first order with a credit for a discount.
The boards arrived yesterday, and assembly has begun. Excellent solder wetting, clean line definition, and drill holes that are precisely in the center of the via lands.
Please convey my gratitude to everyone who created such wonderful boards.
