Abstract

We present an eddy-current test (ECT) method for detecting conductive microbeads on a nonconductive substrate. A Helmholtz coil is used to generate an exciting magnetic field. The magnetic fields, generated by eddy-currents in a Pb-Sn microbead, are detected by a spin-valve giant magnetoresistive (SV-GMR) sensor. The experimental results are compared to an analytical solution for the magnetic field over the microbead. Early results for the detection of a grid of microbeads are also presented.

采用SV-GMR传感器的亥姆霍兹线圈技术检测导电微珠
我们提出了一种检测非导电基板上导电微珠的涡流测试(ECT)方法。亥姆霍兹线圈用来产生激励性磁场。通过自旋阀巨磁阻(SV-GMR)传感器检测由铅锡微珠内涡流产生的磁场。实验结果与微珠磁场的解析解进行了比较。本文还介绍了微珠网格检测的早期结果。
