Whereas traditional handlers are able to align only the positioning of packages as a whole or in groups, the system places each individual package in the optimum position relative to the contactor, even in high parallel test setup. The self alignment is performed in all six degrees of freedom and, therefore, solves any deviations in planarity or outline. Optimizing the package positioning without any drawback on throughput, even for high parallel testing, allows the customer to benefit fully from the speed and capacity of the system.
