Abstract
A wafer testing cassette is provided. The wafer testing cassette includes a first housing, a second housing and a magnetic force generating assembly. The first housing include a probe card, the probe card includes at least one probe having a paramagnetic property. The second housing is combined with the first housing and has a magnetic force generating assembly arranged corresponding to the at least one probe. A wafer located in the second housing, and the at least one probe electrically contacts at least one pad of the wafer with a predetermined contact force. When the magnetic force generating assembly is configured to generate a first magnetic attraction force, the magnetic force generating assembly attracts the at least one probe, so that the at least one probe electrically contacts the at least one pad with a first contact force which is greater than or equal to the predetermined contact force.
