Zusammenfassung: | A device for detecting the position, coplanarity and separation of terminals of printed circuit board components wherein the terminals are consecutively imaged on a topically resolving detector through the use of an illuminating light source, and wherein the direct reflections are suppressed by the use of a polarized light source and by the existence of an optical analyzer in the imaging beam path, resulting in only the diffused reflections being used for imaging to avoid overradiation of the detector. |
