Combination X-ray/Vision Inspection
December 31, 1969 |Estimated reading time: Less than a minute
The XRV is an automated in-line PCB inspection unit that combines visual inspection with the advantages of X-ray. It uses CCD cameras to check for missing or wrong components, misplacement, polarity, and other visually evident defects. The integrated X-ray capability checks for BGA, µBGA, flip chip, J-leads and other hidden solder connections that cannot be seen by the naked eye. A typical PCB with 500 components is said to take less than 30 minutes to program. The system self-learns a PCB by extracting part information from the CAD pick-and-place file and automatically stepping through a known good board.
