1. An electrical connection inspection device comprising:

  • a source of x-rays which emits x-rays through an electrical connection from a plurality of positions;

    an x-ray detector system positioned to receive x-rays produced by said source of x-rays which have penetrated the electrical connection, said x-ray detector system further comprising an output which emits data signals corresponding to an x-ray image of the electrical connection produced by the x-rays received and detected by said x-ray detector after penetrating the electrical connection; and

    an analysis system comprising;

    an image memory which combines said detector data signals to form an image database which contains information sufficient to form a cross-sectional image of a cutting plane of said electrical connection; and

    an image processor which analyzes said image database to determine a measure of the quality of the electrical connection.
