Thermal issues can be handled using the right materials, but these products must be carefully chosen if the electronics is going to be used in a technical situation such as a vacuum or sterile medical environment. This is because under certain conditions gas can be released from a solid which can then have a detrimental effect on many items in the surrounding area.
In a vacuum environment gas can be released from a solid which can then have a detrimental effect on many items; for instance, in satellites the released gas could condense on a camera lens. Medical facilities also must manage outgassing to keep a sterile environment. Therefore, if electronics is being produced for such environments only components, including TIM products, can be selected with acceptably low outgassing.
More information on Outgassing is available in our 'Thermal Management and Outgassing' news article.
