In-circuit test (abbreviated ICT) is a useful and efficient tool for printed circuit board test by measuring each component in turn to check that it is in place and of the correct value. Some in-circuit testers are able to test some of the functionality of some integrated circuits, and in this way give a high degree of confidence in the build and probability of operation of the board. Parameters covering shorts, opens, resistance, capacitance, and other basic quantities can easily show whether the assembly is correctly fabricated and have a very high chance of performing to its specification.
