Abstract
An improved system for and method of testing electrical components under temperature controlled conditions includes a chamber, within which the component can be mounted, for maintaining a predetermined environmental temperature for the component. A window forming part of a wall of the chamber includes a plurality of flexible, substantially transparent, spaced-apart sheets of plastic film. Dry gas is forced through the space between adjacent sheets to prevent moisture from forming on the sheets. A probe needle can be inserted through any random point of the window into contact with the component disposed within the chamber.
