Product Description
The ST-3 digital AI SPI Inspection Machine for SMT Line is designed for manufacturers and assembly operations requiring precise solder paste inspection after printing. It targets SMT production lines aiming to ensure correct solder paste volume, height, and alignment through a 3D inspection process. This system suits enterprises focusing on small component assembly and handling warped or flexible PCBs, enabling quality control in complex manufacturing environments.
Utilizing sinusoidal white light projection combined with a 12-megapixel industrial CCD, the ST-3 offers 3D solder paste volume measurement with repeatability accuracy below 10%. Its non-contact structured light grating avoids mechanical wear, supporting inspection areas up to 500×600 mm. The system provides quick programming and line switching times of 5 and 3 minutes respectively, incorporates 2-axis dynamic profiling to compensate for PCB warping, and operates on a Windows 10 platform with integrated SPC analysis and reporting capabilities.
The machine is adaptable to various SMT production scenarios requiring rapid changeovers and thorough paste inspection. It fits environments with multiple product variants or small batch sizes, where high-density PCBs or flexible printed circuits are common. By enabling consistent solder paste inspection on warped substrates and supporting optional barcode scanning for traceability, it addresses practical manufacturing challenges in SMT assembly lines where accuracy and flexibility are essential.
The ST-3 digital AI SPI Inspection Machine features a non-contact, programmable structured light measurement approach that limits mechanical wear, reducing maintenance requirements. Its quick programming and line changeover times support small-batch and multi-variant production needs. The inclusion of lifetime free software upgrades and compatibility with Gerber formats can simplify integration and long-term sourcing considerations. These elements suit OEM/ODM buyers and production line managers seeking stable inspection solutions for SMT manufacturing.
This inspection system accommodates PCBs with warping and small components through dynamic profiling and high-resolution imaging, aligning with manufacturers’ quality control demands. Integrated SPC functions and optional barcode scanning contribute to process monitoring and traceability, which are important in regulated or high-mix facilities. The machine’s dimensions, power, and air supply requirements are typical for industrial SMT lines, allowing straightforward installation within standard production environments.
