Customized Test Fixtures

The test fixture, a device that interfaces between the ATS and UUT, is necessary for automated testing. Due to different form factors and various connector types, it is impossible to find an off the shelf test fixture that can fit all test requirements. The Chroma 8000 ATS support team not only helps plan and develop the ATS, but the also provide their expertise to tailor a test fixture to the customer’s needs.
