Abstract:
1. A method of using a microelectronic component test system in which a microelectronic component is carried in relation to a head by a microelectronic component support, the method comprising: placing a contact member on the microelectronic component support, the contact member having a conductive contact surface of known planarity; mounting a probe card to the head such that the probe card is electrically coupled to the head and an array of probes is oriented toward the contact member; moving the contact member with respect to the probe card and recording in a first data set a change in contact condition of each of the probes with respect to the contact surface; changing an orientation of the probe card with respect to the contact member; and moving the contact member with respect to the probe card and recording in a second data set a change in contact condition of each of the probes with respect to the contact surface.
