Patent ID: 8217675

Claim:
An electrical testing apparatus for testing an electrical test sample, comprising: a conductor substrate and a test head, a contact spacing converter electrically connecting the conductor substrate to the test head, a first stiffening device mechanically connected to and rigidly securing the conductor substrate, at least one spacer that penetrates the conductor substrate and is mechanically connected to the contact spacing converter, the spacer being held on the first stiffening device by at least one tilt adjusting arrangement; and a tilt element that is mechanically connected by the spacer to the contact spacing converter and is held adjustable for tilt on the first stiffening device by the tilt adjusting arrangement, the tilt element being configured as a tilt plate, wherein the tilt element is rigidly coupled via the spacer to the contact spacing converter, and the spacer penetrates an aperture of the conductor substrate and an aperture of the first stiffening device without physical contact, respectively, and extends as far as the tilt element.
