Temperature

A Thermotron temperature chamber is environmental test equipment used to expose items to controlled hot and cold conditions. Temperature chambers are used to verify whether devices, assemblies, and materials continue to function or remain within specification after thermal exposure. Temperature chambers are support equipment rather than wafer-processing tools, and they are typically used for qualification, reliability work, failure analysis support, and incoming or outgoing product evaluation.

Temperature chambers fit around the manufacturing flow rather than inside a lithography, deposition, etch, diffusion, or metrology sequence. Temperature chambers are commonly used before release to production, after assembly or packaging, during reliability screening, and during engineering investigation of process or design changes. Temperature chambers can also support correlation work between process conditions and later electrical or mechanical behavior.

Temperature chambers are used for thermal cycling, steady-state soak, temperature exposure, and environmental screening of components and subassemblies. Temperature chambers can be used with semiconductor devices, electronic assemblies, sensors, optics, fixtures, and material coupons when engineers need to study thermal effects without performing a wafer fabrication step. Temperature chambers are also used to reveal thermally activated defects, mechanical mismatch problems, seal weaknesses, and temperature-dependent shifts in performance.
