ICT, called online testing, is a standard test method that checks for manufacturing defects and component defects by testing the
electrical characteristics and electrical connections of online components. It mainly checks the individual components on the circuit
and the open circuit and short circuit of each circuit network.It has the characteristics of simple, fast and accurate fault location.
A component-level testing method used to test each component on the assembled circuit board.
ICT is usually in production, it can reflect the manufacturing conditions in time, which is conducive to the improvement
and promotion of the process. The faulty board tested by ICT can greatly improve production efficiency and reduce maintenance
costs due to the accurate fault location and easy maintenance. Because of its specific test items, it is one of the important test
methods for modern mass production quality assurance.
