Technical details and manufacturing context for Semiconductor Test Handler

Definition
A semiconductor test handler is an automated material handling system used in semiconductor manufacturing to transport, position, and sort integrated circuits (ICs) or other semiconductor devices during electrical testing. It interfaces with automatic test equipment (ATE) to perform functional, parametric, and reliability tests on packaged devices, then sorts them into bins based on test results (e.g., pass/fail, speed grades).
Working Principle
The handler receives semiconductor devices from input trays or tubes, then uses pick-and-place mechanisms, conveyors, or gravity-fed tracks to transport individual devices to test sites. At each test site, the device makes electrical contact with test sockets connected to ATE. After testing, the handler moves the device to an output location corresponding to its test result category. Advanced handlers may include thermal control systems for testing at specified temperatures and vision systems for alignment and inspection.
