Wafer test cassette

A wafer test cassette, comprising:

• a first housing including at least one first magnetic member;
• a second housing including at least one second magnetic member, the second magnetic member being arranged corresponding to the first magnetic member;
• wherein, when the first housing and the second housing are correspondingly in contact with each other, an accommodating space is defined between the first housing and the second housing;
• a magnetic barrier assembly configured to be connected to the first housing or the second housing for reducing or eliminating magnetic attraction generated between the first magnetic member and the second magnetic member;
• and
• a probe card and a wafer disposed in the accommodating space;
• wherein the magnetic barrier assembly is configured to reduce or eliminate the magnetic attraction before the first housing and the second housing are in contact with each other;
• wherein, when the first housing and the second housing are correspondingly in contact with each other, an effect of the magnetic barrier assembly is released, so that the first housing and the second housing are tightly coupled to each other through the magnetic attraction;
• and
• wherein the first housing and the second housing tightly coupled to each other through the magnetic attraction are configured to be separable by using the magnetic barrier assembly to reduce the magnetic attraction;
• wherein a first fixing member is configured on an outer edge of the probe card, a second fixing member is configured on an outer edge of the wafer;
• wherein the first magnetic member is a permanent magnet, and the second magnetic member is the permanent magnet or an unmagnetized magnetically permeable object;
• wherein the magnetic barrier assembly is disposed in the first housing or the second housing and between the first magnetic member and the second magnetic member;
• wherein, when the magnetic barrier assembly is configured to move a position to shield the first magnetic member or the second magnetic member, the magnetic attraction generated between the first magnetic member and the second magnetic member is reduced.
