Abstract: A wafer probe test system having a probe card with a probe head, a rotary magnet, a magnetic sensor positioned to sense the magnetic field of the rotary magnet and a controller coupled to the probe card, where the probe head has probe needles to engage features of test sites of a wafer in a wafer plane of orthogonal first and second directions, and the rotary magnet is rotatable around an axis of a third direction to provide a magnetic field to the wafer, in which the controller includes a model of magnetic flux density in the first, second and third directions at the respective test sites of the wafer as a function of a rotational angle of the rotary magnet, a probe needle height along the third direction and a measured magnetic flux density of the magnetic sensor.

Abstract: An enclosure, in accordance with an embodiment of the invention, comprises a plurality of peripheral frame members, a plurality of corner frame members, a plurality of corner members, a plurality of primary surface sheets, and a plurality of secondary surface sheets. In preferred embodiments, the components of the enclosure are joined together in a manner that inhibits liquids from accessing the junctions between the components. In this manner, the interior of the enclosure can be shielded from various weather and other conditions.
