Abstract: A probe card for a testing apparatus of electronic devices comprises at least one testing head which houses a plurality of contact probes, each contact probe having at least one contact tip suitable to abut onto contact pads of a device under test, and a support plate of the testing head associated with a stiffener and an intermediate support, connected to the support plate and suitable to provide a spatial transformation of the distances between contact pads made on the opposite sides thereof. Conveniently, the probe card comprises a support element which is joined to the intermediate support, this support element being made by means of a material having a greater stiffness than the intermediate support, thereby being able to provide local micro rectifications of the intermediate support.
