Abstract
A rotatable or translatable carousel configured to facilitate electrical or electronic testing of Devices Under Test (DUTs) in combination with an insertion handler and a test head is disclosed. The carousel is configured to be placed on a test head of a tester in a first position with a first Device under Test (DUT) (such as a system-on-a-chip (SOC) integrated circuit (IC)) loaded in a first test position of the carousel. A first electrical or electronic test is performed on the first DUT at the first position, after which the carousel is advanced to a second position and a second DUT is loaded in a second test position of the carousel. While the carousel is positioned at the second position, the first test is performed on the second DUT and a second electrical or electronic test is performed on the first DUT. In one embodiment, the process of testing DUTs, inserting DUTs and rotating or translating the carousel in respect of the test head is repeated until all test positions in the carousel have been filled and all desired electrical or electrical tests have been performed on the first DUT. At this point the process of removing fully-tested DUTs from the carousel is optimally undertaken.
