High-precision pin inspection for press-fit operations during the final assembly of printed circuit boards

The Pinspector quality control system, consisting of a Ranger3 3D vision camera and laser technology, detects deviations from the defined quality standard. A three-dimensional, non-contact measurement function is used to check that the pins are correctly aligned with the designated through holes in the printed circuit board. After successful positioning, Pinspector gives the go-ahead for the press-fit process. The three-dimensional position measurement function is run after the press-fit process to monitor the presence, height, and co-planarity of the pins.
