Study on Correction Method for Die Position Deviation caused by adhesive tape puncture

Accurate peeling off and transferring of microchips play a critical role in LED die sorting technology. Generally, sorting efficiency of more than 36 KUPH, and an alignment deviation less than 1 mil (25.4 μm) is required. High precision position control and cooperation of multifactors should be implemented precisely. Among all the factors, the film deformation is an important one. As the sorting p...
