What it is

The Teradyne A 585 is a semiconductor tester. The A 585 is categorized as test and probe equipment.[1][2]

How it works

General reference — not yet source-verified

The Teradyne A 585 operates as an automatic test system that applies electrical stimuli to a device under test and measures the resulting responses. The system architecture typically includes a test head that interfaces with a wafer prober or package handler, a mainframe containing pattern generation and pin electronics, and a control computer for test program execution. The tester compares measured responses against expected values to determine pass or fail status for each device.

Where it fits in the process flow

General reference — not yet source-verified

The Teradyne A 585 is used in the semiconductor manufacturing process after wafer fabrication and before final packaging, in a step known as wafer sort or probe test. In this step, the tester works with a prober to test individual die on a wafer while still in wafer form. The A 585 can also be used for final test after devices are packaged, where it interfaces with a handler to test finished components.

Applications

General reference — not yet source-verified

The Teradyne A 585 is applied to parametric and functional testing of semiconductor devices, including digital logic, memory, and mixed-signal circuits. The system is suited for both engineering characterization and high-volume production testing environments.
