 note = {This paper describes high-speed printed circuit board (PCB) inspection based on eddy-current testing (ECT) technique. The proposed ECT probe consists only of meander exciter coil and multi spin-valve giant magnetoresistance (SV-GMR) sensor that it was designed for detection of microcrack on PCB surface. To conduct high-speed scanning, harmonic analysis based on Fourier analysis is applied to acquire ECT signal at fundamental frequency. Signal variation at defect point is enhanced by applied averaging of multisignal obtained from the multi SV-GMR sensor., Special Issue of the Asia-Pacific Symposium on Applied Electromagnetics and Mechanics (APSAEM06)},
