A wafer prober is a machine used to test integrated circuits. For electrical testing a set of microscopic contacts or probes called a probe card are held in place whilst the wafer, vacuum-mounted on a wafer chuck, is moved into electrical contact.fter IC packaging, a packaged chip will be tested again during the IC testing phase, usually with the same or very similar test patterns.
