Abstract
An environmental testing facility for verifying operational conditions of electronic components at predefined temperature extremes is described. A removable multistation holder is configured to have a plurality of components coupled thereto. The multistation holder is coupled to a controllable, rotatable shaft. A hood is placed over the holder, shaft and associated apparatus and placed in contact with a base plate, so that a vacuum can be established in the resulting chamber. A sensing device permits the positioning of the individual components with respect to an interface apparatus. When the component is correctly positioned with respect to the interface apparatus, the interface apparatus is moved to engage the terminals of the components. The electrical signals can be applied to and received from the component through the interface device. After a first temperature condition is established for the multistation holder and consequently for the components coupled thereto, all of the components are tested. Thereafter, the components are tested at the second temperature condition. The testing apparatus is operated under control of data processing circuits that can apply and receive signals from the components for operation evaluation and can automatically position the components with respect to the interface apparatus, and can provide appropriate signals for a sequence of the testing procedure.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
