Abstract
Abstract A multiple device fixture, used in conjunction with a temperature forcing unit, provides flow and direction control of conditioned air from the temperature forcing unit to two or more integrated circuits during temperature testing or characterization. The multiple device fixture provides an efficient way to temperature test multiple electronic devices simultaneously over accurately controlled temperature ranges when an automated device handler is not available, does not exist for a specific package type or is too expensive.
