When designing electronics, heat dissipated to the surroundings by micro devices is an important consideration because heat has a powerful and stringent effect on their operation and lifespan. When an electronic device overheats, components start to wear out more quickly, degrade, cross the threshold into safe mode, and then stop functioning. The consequences can eventually cause premature failure to the whole system. Therefore, as these technologies continue to develop, thermal management plays an influential role in the functionality and performance of today’s electronic devices.
