Abstract:
Disclosed is an NDT/NDI probe array and manufacturing method. The probe array includes a sheet of flexible circuit 10 with a plurality of lower pins 102 and corresponding, electrically connected, upper pins 104. The probe further comprises a backing block 12, a layer of piezoelectric ceramic 16 having a plurality of conductive elements 162, a matching layer 18 and a frame 14. An adhesive material such as epoxy is applied to the circuit, the backing, the ceramic and the matching layer, and all are aligned and stack pressed at least partially into the frame and permanently bonded in such a fashion that each of the lower pins of the flexible circuit is firmly and permanently in contact with a corresponding one of the conductive elements of the ceramic.
