Allow us the opportunity to provide you with exceptional service and quality custom test fixture … It works similarly to an MDA but differs in high voltage usage. Specialized and custom designed PCB testing jigs and fixtures are used to test PCB. In most cases, the test is designed for 100% coverage, but you’ll get closer to 85-90% coverage. 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. D416,212 Handle for Test Fixture. They should be sufficient to allow the probe to make contact, and should have space around them to take up any tolerances in the fixture, PCB, etc, so that the probes do not cause shorts. Thus, you can automatically produce about 80% of the programs. RNS can customize the functional fixture for virtually any requirement or contingency.
