Evaluating the surface structure of construction elements using various presentation angles

摘要

The method involves scanning an electronic component (110) by a relative movement (122) between the electronic component and an illumination light (102), and illuminating the electronic component under an angle. The electronic component is newly scanned by a new relative movement between the electronic component and the illumination light. The electronic component is illuminated under another angle that is different from the former angle. A measuring light (107) is newly held, where the measuring light is scattered-back by the electronic component partially on a light detector (106). Independent claims are also included for the following: (1) a device for optically evaluating a three-dimensional surface structure of electronic component (2) an assembly machine for assembling printed circuit boards with electronic components (3) a computer readable medium with a program for optically evaluating a three-dimensional surface structure of an electronic component.
