What it is
How it works
General reference — not yet source-verifiedAs an analog VLSI test system, the A500 applies electrical stimuli to a device under test (DUT) and measures its analog and mixed-signal responses.
Automatic test equipment of this class typically uses a test head that interfaces with the DUT via a probe card or test socket, along with a host controller running test programs.
Where it fits in the process flow
General reference — not yet source-verifiedThe A500 is used in semiconductor manufacturing to test individual integrated circuits, typically after wafer fabrication and before packaging.
The A500 sits between the fabrication and assembly stages, providing electrical verification that devices meet their analog and mixed-signal specifications before final packaging or system integration.
Applications
The A500 is used in the testing of analog and mixed-signal integrated circuits, such as data converters, operational amplifiers, and interface devices.[1]
