According to the specifications of a coating plan, the presence of the coating is checked but also area’s with too much coating or where lacquer should not be present are detected.The Multi Line CCI has a high-resolution color camera with telecentric optics for razor-sharp images. In combination with UV illumination from above and from the side, high-contrast images are produced.
The UV lighting causes the ultraviolet fluorescent particles in the coat to glow. This reveals defects such as scratches and bubbles. Above all, however, it also reveals whether there is too much or too little coat on the assembly.
As a special feature, the PCBA can be simultaneously inspect both top and bottom without turning, and, if necessary, can also be transported back to the beginning of the line using a lower level return conveyor.
