Abstract:

Positive Temperature Coefficient (PTC) heaters offer precise temperature control due to their material property, which shows high resistance to temperature. The proposed design of the etching system based on a PTC heater is compared with an ordinary resistor-based system in terms of performance. The analysis includes power consumption, temperature deviation, geometrical deviation, and machining cost. The comparative result shows that the PTC heater-based system maintains temperature with a deviation of ±0.5 °C, compared to ±1.5 °C for the conventional resistor-based system. The total power consumption was reduced in the PTC heater-based system to 0.44KWh from 1 kWh. The overall analysis shows a reduction in power consumption, which ultimately results in a cost reduction and improved product quality. This PTC heater-based system approach shows an alternative to the conventional ordinary heater-based etching system.
