Conformal coatings for electronic military applications

Dodatki: Conformal Coatings, Thermal Management

Electronics for military applications are expected to operate first-time, every time in some of the most varied and demanding environmental conditions known to man. Military programs often run over several decades and hardware will often be updated several times during the life of the program. Most aerospace electronics, will be exposed to significant amounts of vibration, often extreme variations in operating temperature (depending on whether the electronics are situated in cabin or non-heated areas), as well as the opportunity to be exposed to cleaning chemicals and de-icing fluids etc. Commercial and military aerospace applications will typically have multi-decade program lifetimes and the hardware will usually be upgraded several times during its service life.

Effective Thermal Management

Dodatki: Thermal Management, Encapsulation Resins

During use, some electronic components can generate significant amounts of heat. Failure to effectively dissipate this heat away from the component and the device can lead to reliability concerns and reduced operational lifetimes. Newton’s law of cooling states that the rate of loss of heat is proportional to the temperature difference between the body and its surroundings. Therefore, as the temperature of the component increases and reaches its equilibrium temperature, the rate of heat loss per second will equate to the heat produced per second within the component. This temperature may be high enough to significantly shorten the life of the component or even cause the device to fail. It is in such cases that thermal management measures need to be taken. The same considerations can be applied to a complete circuit or device which incorporates heat producing individual components. Więcej informacji >
