Abstract
An apparatus and associated method are provided for treating a workpiece with a cryogenic impingement fluid. A fixture supports the workpiece in an upright position and operably connects an electrical component of the workpiece to a power source in the supported position. A cryogenic impingement fluid applicator sprays a stream of the cryogenic impingement fluid against the supported workpiece and laterally moves the stream in accordance with a predetermined path. A shield deflects the stream of cryogenic impingement fluid to prevent the stream from contacting at least a part of the workpiece as the stream is moved along the predetermined path.
