ABSTRACT:
A micropositionable contactor for use in automated testing of multiterminal electronic devices includes an elongated metal probe having a contact at one end. A plurality of piezoelectric motors are positioned about the probe are operative to move the probe in a corresponding plurality of directions. Digital electronic circuit means are coupled to the piezoelectric motors to move the probe through a sequence of motions which establish the locations of each contact on the device under test and make appropriate testing connections to one or more of the device contacts.
