MICRO-ASSEMBLY AND TEST STATION APPLIED FOR THE CHIP AND BAR TESTER APPLICATION

摘要

Manipulator for use in the field of robotics are currently limited in their range of movements. A manipulator (10) to enable a wider range of movements comprises a first positioning member (11) having a free end (117) and a lower positioning resolution, and a second positioning member (22) mounted on the free end of the first positioning member and having a higher positioning resolution. In operation, the first positioning member provides for coarser positional adjustment while the second positioning member provides for finer positional adjustment so that the second positioning member mounted on the free end of the first positioning member improves the positioning resolution of the manipulator from the lower positioning resolution to the higher positioning resolution. A corresponding method of improving a positioning resolution of a manipulator with a first positioning member (11) having a free end (117) and a first positioning resolution, comprises mounting on the free end of the first positioning member a second positioning member (22) having a second positioning resolution higher than the first positioning resolution.
