In-circuit testing (ICT) is the most robust type of PCB testing in existence. It optimally replaces costly test fixtures which are often inflexible. In-circuit test (ICT) is an example of white box testing where an electrical probe tests a populated printed circuit board (PCB), checking for shorts, opens, resistance, capacitance, and other basic quantities which will show whether the assembly was correctly fabricated. Test fixture solutions for printed circuit board design and assembly is a crucial part of the manufacturing process. As the name suggests, you use its operation to test cables optimally. Customised Your Production In-Circuit Test Station PCB Fixture PCB tester board is typically constructed with the following components on board. PCB Testing Jig & Customized Fixture offers manufacturers repeat-ability, accuracy and interchangeability to test or program their finished circuit products or PCBs. It works similarly to an MDA but differs in high voltage usage. Standoff feet below the fixture to give the option whether or not they mounted directly to test table and/or allow clearance for additional hardware. This line of overclamps feature precision machined aluminum and stainless steel parts for superior strength and smooth operation. A test jig facilitates the probe of defined test points to help determine the expected inputs and outputs of the PCB. Mechanical Fixtures - Printed Circuit Board Test Fixtures.
