  • Eddy current sensor for non-destructive testing the quality of electrically conductive through-hole plating in printed circuit boards
    Patent number: 4060760
    Abstract: An eddy current sensor for non-destructive testing the quality of electrically conductive through-hole plating in printed circuit boards in which a magnetic probe member is provided with a device for moving the probe enveloping its exciting winding and two opposing measuring windings which are magnetically coupled with the exciting winding. These exciting and two opposing measuring windings are rigidly connected so that the exciting winding is positioned between the measuring windings with gaps provided to insert a printed circuit board to be tested. The magnetic probe member is inserted into the hole with the help of the device for moving the probe.
