In the PCB industry, WHEC CIS line scan cameras are mainly used for comprehensive quality control applications including surface defect detection, hole integrity verification, component absence identification, foreign material detection, dimensional metrology, and optical character recognition (OCR) verification.
Compared to conventional cameras, CIS line scan camera offers distinct advantages in the PCB inspection field, such as a compact design, easy assembly, 1:1 imaging, and no image distortion. A single CIS line scan camera can scan up to 3000mm without the need for image stitching. The 1:1 imaging capability ensures consistent defect imaging with a telecentric view, making it easier to trace defects across different process steps.
