Enables early detection of production problems to prevent loss
The Strip-to-Strip Inspection after Plating guarantees the quality of WIP products with fast feedback loop. When manufacturing cost and quality are a concern, the PHIXEL MIS minimizes waste and loss — enabling early detection of defects usually only discovered during the final 4th Optical inspection of finished products. With ultra-high-speed vision scan, high-precision for 2D inspection DFN products, high accuracy laser for reject treatment, and fast conversion, the PHIXEL MIS supports the largest strip size: 100 x 300 mm.
