Abstract: A probe card for a testing apparatus of electronic devices comprises a probe head housing a plurality of contact probes, each contact probe having at least one contact tip adapted to abut onto contact pads of a device under test, as well as a main support and an intermediate support connected to the main support and adapted to realize a spatial transformation of distances between contact pads on its opposite faces as a space transformer, the probe card suitably also comprising at least one connecting element adapted to link the space transformer and the main support, this connecting element having a substantially rod-like body and being equipped with a first end portion comprising at least one terminal section adapted to be engaged in a corresponding housing realized in the space transformer and with a second terminal portion adapted to abut onto an abutment element linked to the main support.
