Home/Technical Glossary/Bake-Out Oven Bake-Out Oven Bake-out is a term which refers to the use of heat to release volatile compounds like moisture from something as a form of cleaning or processing. In various component manufacturing processes, like electronic component package sealing, the term is used to refer to a period of time where a part or device is placed in a vacuum chamber and heated driving off moisture and gases which can then be removed by a vacuum pump system. AMADA WELD TECH’s SA2200 Vacuum Bakeout Oven is a good example of this technology.
