In today’s fast-moving electronics manufacturing industry, efficiency and precision are key. At PCBasic, our advanced SMT line operates under strict quality control to ensure each circuit board meets the highest standards of reliability and performance. Combined with our one-stop PCB assembly service, we provide customers around the world with rapid turnaround, exceptional quality, and full-process manufacturing—from prototype to mass production.
What Is an SMT Line?
SMT (Surface Mount Technology) is the foundation of modern PCB assembly. An SMT line refers to the complete production flow where electronic components are automatically placed and soldered onto circuit boards.
A typical SMT line at PCBasic includes multiple fully automated stations, such as solder paste printing, SPI (solder paste inspection), high-speed placement machines, nitrogen reflow ovens, AOI (automated optical inspection), and X-ray inspection for BGA and QFN packages. Each step is digitally monitored through our MES+ERP+CRM system to guarantee accuracy, traceability, and consistency.
PCBasic’s Advanced SMT Line Process
At PCBasic, every SMT line follows a standardized and intelligent process to deliver stable, high-yield results:
- Solder Paste Printing – Using precision stencil printers with automatic alignment and 3D SPI inspection, we ensure uniform solder paste deposition.
- High-Speed Component Placement – Our SMT machines can place up to 250,000 components per hour, supporting packages down to 01005 and fine-pitch BGAs.
3. Nitrogen reflow soldering by introducing 99.99 percent pure nitrogen, we can effectively stop the formation of oxidation, minimize solder voids, and guarantee seamless, clear joints.
4. 3D AOI and Xray Inspection Each board is checked automatically following the reflow. Solder joints that are hidden and the inside layers are scrutinized through 3D X-ray to guarantee that there are no imperfections.
5. Selective Wave Soldering (THT) – For mixed-assembly boards Our selective soldering process can achieve at least 95% of the tin penetrated, with solid and consistent joints.
6. Functional Test (FCT and ICT) – Each assembled PCB goes through a rigorous testing process to verify its functionality prior to packaging and delivery.
