In this paper we developed the Teflon heater which contains a built in temperature sensor and a relay for improved plating equipment system. Teflon heater is improved by using Pt 100Ω sensor which can detect until 600°C. When the bath temperature sensor detects over 60°C or the Teflon heater sensor detects over 240°C they temporarily shut down the heater to control temperature. Also relay completely shuts down main power when detects instant temperature is detected over 5% of 240°C by the heater sensor to prevent teflon melting down and fire spreads. Developed plating equipment system can monitor a real time temperature in the teflon tube and bath water. Therefore we think the proposed plating equipment can eliminate the possibility of fire in plating processes fundamentally.
