Method of automatically carrying IC-chips, on a planar array of vacuum nozzles, to a variable target in a chip tester |
摘要 |
A method of automatically carrying IC-chips, on a planar array of vacuum nozzles, to a variable target in a chip tester uses a set of laser distance sensors to align the vacuum nozzles with the target. Alignment occurs when certain combinations of distance and distance changes are sensed.
