Product Description
The functional testing system starts with a mechanical fixture—also known as a test fixture—that is used to secure the device under test (DUT). Because they employ spring pins—also referred to as spring probes or test probes—they are also called bed-of-nails test fixtures. These testers come from many different manufacturers, and their costs, durability, and even functionalities vary considerably.
The test fixtures strike an excellent balance between cost and reliability. They offer numerous basic options suitable for a wide range of DUT sizes and anticipated production volumes. We also appreciate their interchangeable cartridge system, which makes it easier for the QA team to perform large-scale testing of multiple PCB designs. The cartridges are machined to fit each specific DUT and are designed to be fully interchangeable.
For smaller-batch products, cheaper options can be used. Typically, bakelite test fixtures offered by various overseas suppliers are available. Usually, the entire fixture is customized for each DUT, since the probe boards are not interchangeable.
After selecting the test fixture, you’ll need to customize it to fit the DUT. Use CAD software (such as Fusion 360) to design a model that matches the test points on the DUT with the spring-pin holes on the fixture. You’ll also need a method for mounting the DUT—typically by aligning the mounting holes on the PCBA with the conductive pins on the fixture.
