Optical inspection system for PCB coating

For a manufacturer of equipment for the electronics industry, we have realised an optical inspection system based on GigE colour cameras, which reads barcodes and plain text on the objects (OCR) and determines the position and location of fiducials.

In addition to providing the respective live images, individual images are stitched to display entire assemblies. In the application, 12 images must be seamlessly stitched together, which is ensured by prior calibration and removal of distortions as well as a very homogeneous lighting concept.

The customer receives all cameras pre-calibrated by phil-vision and only has to adjust the x/y position precisely.

More information about the calibration targets used, you will find HERE.
