Selectively configurable probe structures, e.g., selectively configurable probe cards for testing microelectronic components
First Claim
1. A method of testing a microelectronic component with a selectively configurable probe card, comprising:
- at a first temperature, contacting each of a plurality of contacts carried by the microelectronic component with one of a plurality of probes carried by the probe card, the probes being arranged in a first probe arrangement;
changing the temperature of the microelectronic component, thereby altering a relative arrangement of the contacts from a first contact arrangement to a different second contact arrangement;
actuating a plurality of actuators to rearrange the probes to a second probe arrangement wherein each of the probes is positioned to correspond to a position of one of the contacts in the second contact arrangement.

Abstract
Microelectronic components are commonly tested with probe cards. Certain aspects of probes, probe cards, and methods of testing microelectronic components are discussed herein. In one specific example, a probe card includes a base and a probe carried by the base. An actuator is associated with the probe and is adapted to selectively position the probe with respect to an electrical contact on the microelectronic component. A test power circuit is coupled to the first probe and adapted to deliver test power to the first probe. In one exemplary method, an actuator is actuated to move the probe from a first probe arrangement to a second probe arrangement.
