In Circuit Test (ICT) is an electrical test which quickly processes boards at high speed to determine if the board was manufactured properly. ICT verifies that all required components are on the board and correctly installed, delivering an easy-to-understand test printout which directs test operators to the exact point of failure. Another common feature is to add functional tests in your ICT fixture – thus increasing the amount of up-front coverage. LED testing, Analog to Digital and Digital to Analog Converter testing, and other features are becoming increasingly popular.

ICT is a test methodology utilizing electrical probe tests on an assembly. ICT typically goes after manufacturing errors by measuring shorts, opens, capacitance, and resistance. However, advancements in technology have allowed us to enhance ICT testing by adding a component of functional testing. Recent advances have allowed us to incorporate additional functional and embedded tests into these ICT applications, thus allowing for earlier diagnostics in the manufacturing cycle.
