摘要

PPROBLEM TO BE SOLVED: To provide a coil design method which enables arrangement beforehand the coils used as the magnetic sensor for fault diagnosis of a substrate in suitable form and location. PSOLUTION: Induced electromotive force sensitivity specifies the frequency range which is larger than the predetermined level, based on the induced electromotive force frequency characteristics, concerning the relation between the frequency of flowing electric current through a circuit pattern 22 to be inspected, and the induced electromotive force observed with the coil. The wire length of a coil 30 is established as the range of the wire length, corresponding to the specified frequency range, based on the coil length frequency characteristics, showing the relation between the drive frequency and the coil line length. The detection sensitivity with respect to the induced electromotive force observed with the coil 30 is set so that it becomes higher, in consideration of the physical restrictions and the magnetic flux density distribution at pattern formation, the opening space, the number of winding, etc., as well as taking into account the arranged position and the shape of the coil 30, in relation to the circuit pattern 22.

要解决的问题：提供一种线圈设计方法，该方法能够预先布置用作磁性传感器的线圈，以合适的形式和位置诊断基板的故障。

解决方案：感应电动势灵敏度基于感应电动势频率特性来指定大于预定水平的频率范围，该频率范围涉及流过要检查的电路图案22的电流的频率之间的关系，并且线圈观察到的感应电动势。基于线圈长度频率特性，将线圈30的线长确定为与指定频率范围相对应的线长范围，该线长范围表示驱动频率与线圈线长之间的关系。考虑到物理限制和图案形成时的磁通密度分布，开口空间，绕组数等，将相对于在线圈30上观察到的感应电动势的检测灵敏度设定为更高。 ，并且考虑到线圈30相对于电路图案22的布置位置和形状。
