Enhanced Short Tests for High Impedance Nodes
애플리케이션 노트
This application note introduces an Enhanced Short Test algorithm tailored to tackle the testing challenges associated with high-impedance nodes in Printed Circuit Board Assemblies (PCBAs). Integrated into the Keysight In-Line High-Density In-Circuit Test (ICT) system, the Enhanced Short Test significantly boosts the efficiency of short detection for high-impedance nodes, leading to a noteworthy 57% reduction in testing time. High-impedance nodes, commonly found in modern PCBAs to enhance signal quality and reduce power consumption, present difficulties such as extended stabilization times, heightened sensitivity, diminished current flow, intricate isolation procedures, and concerns regarding signal stability.
