Test Fixture
A test fixture is the mechanical and electrical interface between the test system and the device under test. It ensures that printed circuit boards or assemblies are precisely positioned, securely guided, and reliably contacted.
In modern test processes, it is not only stable contact that matters, but also flexible adaptation, ease of use, and short setup times. The Fixture Series addresses precisely these requirements: with modular adapter structures, interchangeable cassettes, defined Interfaces, and service-friendly access to key components.
Test Fixtures are used in PCB testing, Functional Tests, and automated test systems. They form the basis for reproducible test results, efficient workflows, and a process-reliable connection between the device under test, the Test Fixture, and the test system.
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.
