SMT Assembly Manufacturing Service

Surface Mount Technology (SMT) is a key electronic assembly process that enables high-density component placement, improved production efficiency, and reliable circuit performance. Compared with traditional through-hole assembly, SMT technology allows smaller component sizes, more compact PCB designs, and higher production consistency.

Huayihai provides professional SMT assembly services covering solder paste printing, component placement, reflow soldering, AOI inspection, and quality testing. With automated production equipment and experienced engineering teams, we support customers from prototype builds to high-volume manufacturing.

SMT Assembly Process

1. Solder Paste Printing

High-precision solder paste printing ensures accurate application on PCB pads, providing a strong foundation for reliable solder joints.

2. Component Placement

Automated pick-and-place machines accurately mount surface mount components including ICs, resistors, capacitors, and fine-pitch devices.

3. Reflow Soldering

Controlled reflow soldering melts solder paste and creates reliable connections between components and PCB pads.

4. AOI Inspection

Automated Optical Inspection (AOI) detects soldering defects, missing components, incorrect placement, and other assembly issues.

5. Testing & Quality Control

Electrical testing and functional testing ensure assembled boards meet customer requirements before shipment.
