PCBPN for inspection of holes with diameters between 5.5 and 25 mm
An integrated LED source (for PCBP0xx and PCBPN013-WG) illuminates the cavity both diffusely and directly. The diagram on the left shows the different illumination areas. Diffused illumination is used for defect detection and component inspection.
Direct/specular illumination can be efficiently used to check for surface deformation on metal and highly reflective objects as well as to measure the hole diameter.
The image of the cavity covers around 50% of the detector height; the continuous red line indicates the bottom view of the cavity, the dashed line shows the upper view while the dash-dotted line refers to the lateral view.
