Product Overview

The ICT Tester is a high-density PCB/PCBA in-circuit testing system designed for online production testing. It features a large-scale matrix switching architecture, supporting up to 4,608 test points in the standard configuration and expandable to more than 10,000 points. The system supports dynamic switching measurements between any two test points on the PCB, enabling high-precision measurement of resistance, capacitance, and leakage current. With nanoampere-level weak signal detection capability, it is specifically designed for static testing of open circuits, short circuits, and component faults in high-density PCBs and complex electronic modules. It is suitable for mass production testing and laboratory reliability verification of high-density motherboards and multi-layer PCBs.
