Abstract: Disclosed is an enhanced conformal coating, a process for making the same, and several computer related applications. A commercially available conformal coating is combined with a commercially available blowing agent (sometimes called a “foaming agent”) to create an enhanced conformal coating. The formulation of the enhanced coating is such that it will emit a particular gas when heated to a particular temperature. The enhanced coating is then applied to an object to which pre-damage heat detection is desired. A sensor, located proximate to the object, is then used to detect the emitted gas. Once the gas is detected, actions can be taken to reduce the heat in a manner appropriate for the particular object. Application of the enhanced coating within the computer industry can involve its use with a particular electrical component or a group of electrical components (e.g., a circuit board). For example, the enhanced coating can be applied to one or more circuit boards.
