ICT probe mainly used for in-circuit testing and functional testing, detecting the electrical performance of in-circuit components and the connection of circuit networks. They are able to quantitatively measure and perform functional testing on components.

Usually, ICT probes are used with receptacles of matching sizes, which are fixed on PCB for replacement of probes anytime.
