20. A probe station comprising:
-
(a) a platen suitable for supporting a probe for testing a device under test; (b) a chuck suitable for supporting said device under test thereon; (c) an enclosure at least partially surrounding said chuck, wherein said enclosure defines an opening; (d) a conductive member supported by said platen that encompasses at least 70 percent of said opening; (e) the combination of said conductive member and said chuck laterally movable with respect to said platen while at least a portion of said conductive member and said chuck maintain a fixed relationship with respect to one another; and (f) said conductive member defining an opening therein through which said probe extends to test said device under test.
