What is ICT? The Role of ICT Testing in PCBA Evaluation

In-Circuit Testing (ICT) is an automated electrical test method used in PCB assembly to detect faults like short circuits, open circuits, and component defects by testing the functionality and parameters of individual components within an intact circuit.

Rationale for Incorporating Test Points in PCB Design

Adding test points to circuit board design facilitates comprehensive testing, ensuring soldering integrity and performance compliance post-PCBA completion, critical for identifying open or short circuits without compromising SMT component integrity, although challenges arise with needle bed testing on high-density boards, prompting consideration of alternative methods like JTAG, X-Ray, and AOI.
