Изобретение относится к средствам вихретокового контроля отверстий и трубок малого диаметра и может быть использовано, в частности, для контроля металлизации отверстий печатных плат. Датчик содержит осесимметричный вытянутый вдоль оси симметрии каркас и расположенную на боковой поверхности каркаса обмотку в виде вытянутой вдоль оси каркаса спирали. Каркас выполнен полым с отношением наружного D и внутреннего d поперечного размеров в интервале 1/4<>D/d<>1/6, а обмотка расположена на внутренней поверхности каркаса. Внутренняя полость каркаса может быть заполнена магнитопроводящим материалом. Возможна установка центрального стержня с суживающейся заглушкой. Предложенная конструкция позволяет повысить механическую прочность датчика, предотвратить механические повреждения обмотки без увеличения поперечного габарита датчика. Способ изготовления датчика включает изготовление плоской развертки каркаса, формирование обмотки на плоской диэлектрической эластичной подложке, наложение диэлектрической эластичной подложки на плоскую развертку каркаса. После выполнения указанных операций придают необходимую форму каркасу вместе с подложкой и обмоткой. Это позволяет выполнить предложенную конструкцию при наружном диаметре, составляющем доли миллиметров.The invention relates to eddy current monitoring of holes and tubes of small diameter and can be used, in particular, to control the metallization of holes in printed circuit boards. The sensor contains an axisymmetric frame extended along the axis of symmetry and a winding located on the side surface of the frame in the form of a spiral elongated along the axis of the frame. The frame is hollow with a ratio of the outer D and inner d of transverse dimensions in the range 1/4 <> D / d <> 1/6, and the winding is located on the inner surface of the frame. The internal cavity of the frame may be filled with a magnetically conductive material. Installation of the central core with a tapering plug is possible. The proposed design allows to increase the mechanical strength of the sensor, to prevent mechanical damage to the winding without increasing the transverse dimension of the sensor. A method of manufacturing a sensor includes manufacturing a flat scan of the frame, forming a winding on a flat dielectric elastic substrate, applying a dielectric elastic substrate to a flat scan of the frame. After performing these operations give the necessary shape to the frame together with the substrate and the winding. This allows you to perform the proposed design with an outer diameter of a fraction of millimeters.
