Abstract
A hybrid optical-electrical automated testing equipment (ATE) system can implement a workpress assembly that can interface with a device under test (DUT) and a load board that holds the DUT during testing, analysis, and calibration. A test hand can actuate to position the DUT on a socket and align one or more alignment features. The workpress assembly can include two optical interfaces that are optically coupled such that light can be provided to a side of the DUT that is facing away from the load board, thereby enabling the ATE system to perform simultaneous optical and electrical testing of the DUT.
