Tester Soft Ltd. Have stressed in AOI industry for a long time, we develop the Metal Mask/Stencil Inspection System in 2006 instead of human inspection.
There are some problems of human inspection. End user could not measure the aperture size by putting the measuring tools on the metal mask/stencil.
Because the contents of the metal mask/stencil is almost round hole, the worker is not easy to confirm whether the number of round holes is correct and other issues
The principle of AOI: Computer program is the core. The digital camera will capture the images, After the capturing the system will process the images with the pre-define recipe to detect the defects. The defects will be displayed for reviewing and repairing. The inspection system can reduce damages and promote product quality.
