Abstract
Electrostatic discharge during thermal shock testing on an electronic device (12) by alternate immersion in hot and cold baths (14, 16) of a fully-fluorinated liquid (20) can be reduced by carrying the device within a first, electrically conductive, open-weave basket (32) enclosed within, and coupled to a second basket (30) of similar construction, but a looser weave. The first basket acts as a Faraday shield about the electronic device when both baskets are alternately immersed in the hot and cold baths.
