When an electric current is applied to the conductive traces of a thick film heater, the current flows through the resistive element, which has a high electrical resistance. As the current flows through the resistive element, it encounters resistance, and this resistance generates heat.
The heat generated by the resistive element is then transferred to the surrounding environment through conduction and radiation. The substrate on which the resistive element is printed acts as a heat sink, helping to dissipate the heat and prevent the resistive element from overheating.
Thick film heaters are designed to provide rapid and uniform heating, thanks to their high thermal conductivity and low thermal mass. They can reach high temperatures quickly and maintain precise temperature control, making them ideal for a wide range of industrial and commercial applications.
