High-Spatial Resolution Giant Magnetoresistive Sensors - Part I: Application in Non-Destructive Evaluation

In this chapter, we report the utilization of spin-valve type giant magnetoresistance (GMR) sensors in non-destructive evaluation (NDE). The NDE application is the inspection of high-density printed circuit boards (PCBs) based on the eddy-current testing (ECT) technique. An ECT probe with a GMR sensor is presented for the inspection of high-density double-layer PCB models. The utilization of a GMR sensor as a magnetic sensor showed that PCB inspection could be performed with high-spatial resolution and sensitivity, over a large frequency range.
