A custom designed lens gives a parallax and distortion free picture, because the streams of light fall absolutely parallel from the test object on to the CCD. The placement or CAD data which is imported from GERBER or Placer files is the basis for the test program. In this way, it is impossible for parallax errors to arise, especially in the case of the small components.
Incorrect solder joints and terminations are found easily. The identification of these poor process errors helps to increase production yields and guarantee increased quality. The modus technology is an innovative proprietary development, it is utilized in all our scanner systems.
