Test Fixture
A test fixture is a mechanical and electrical interface between the test system and the device under test, which is used in automated test systems. It serves to precisely hold Contact Probes and connect to defined test points on electronic assemblies or printed circuit boards. This ensures a reliable and reproducible electrical connection during the test process.
Test Fixtures enable the transmission of measurement signals, test currents, and test signals between the test system and the device under test and are a central component of applications such as In-Circuit Test (ICT), Functional Test (Fct), Connector Testing, or Wire Harness Testing. Their mechanical design ensures precise positioning of the Contact Probes and stable contact conditions for accurate and repeatable test results.
FAQ
They ensure that Contact Probes always hit the intended test points precisely and that stable electrical connections are established.
Contact probes establish the electrical connection between the Test Fixture and the device under test and transmit measurement signals or test currents during the test process.
Typical components include Spring Contact Probes, receptacles, Spacer Receptacles, contact blocks, and mechanical mounts.
