Wafer Prober

Wafer probers are used to test integrated circuits by aligning a set of microscopic contacts or pads with needle like probes in a probe card,  The card is held in place while the wafer, vacuum-mounted on a wafer chuck, is moved into electrical contact.  When a die (or array of die) have been electrically tested the prober moves the wafer to the next die (or array) and the next test can start. The wafer prober is typically also responsible for loading and unloading the wafers from their carrier and is equipped with automatic pattern recognition optics capable of aligning the wafer with sufficient accuracy to ensure accurate registration between the contact pads on the wafer and the tips of the probes.
