The Teradyne Ultra Flex DC LSI is an IC tester. The Teradyne Ultra Flex DC LSI is classified under the Test & Probe category.[1][2]
What it is
General reference — not yet source-verifiedThe Teradyne Ultra Flex DC LSI is an automated test equipment system for semiconductor device testing. The system is part of the UltraFlex family of test platforms from Teradyne. UltraFlex systems are used for testing system-on-chip and other complex integrated circuits.
How it works
General reference — not yet source-verifiedA Teradyne Ultra Flex DC LSI system consists of a test controller and a test head that interfaces with devices being tested. The test head contains instrument modules for generating and measuring electrical signals. The system applies test patterns and measures device responses to verify functionality and parametric performance.
Where it fits in the process flow
General reference — not yet source-verifiedThe Ultra Flex DC LSI is used in semiconductor manufacturing for final test of packaged devices or for wafer probe testing. In final test, devices are tested after packaging to verify electrical specifications. In wafer probe, the system tests devices while they are still on the wafer, before dicing.
Applications
General reference — not yet source-verifiedThe Ultra Flex DC LSI is applied to testing a wide range of semiconductor devices, including digital, mixed-signal, and analog circuits. The system performs DC parametric measurements and functional pattern testing. Typical applications include testing SoCs, microcontrollers, and memory devices.
