     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.



Advantage of ICT:


      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.
