By using metal resistance paste as the main raw material, a pure resistance layer circuit is formed by printing, which has stable power after being electrified. In the later stage, the insulating medium, resistance, conductor, thermistor paste and other materials are added, and then sintered at high temperature.202007012004276dabaf94ef84498ca07132d29ba86b79 The thickness of thick film circuit is 3-50 μ, and the circuit with film thickness more than 10μ is called thick film circuit. High power density, size can be made according to requirements, widely used in fine, small parts and other applications. The response speed is very fast, and it can be heated when it is electrified. It is applied to the appliance of instant heating, such as instant hot water dispenser,Faucet, small kitchen treasure, soybean milk machine, wall breaking machine, etc. At the same time, it has high mechanical strength, anti vibration and strong thermal shock resistance. The most important is energy saving, low power attenuation, no direct contact with the heating body, not easy to structure, heat conversion rate up to 96%.


In addition, the thick film heating element can also achieve PTC characteristics, and the resistance of thick film circuit rises sharply at a certain temperature (Curie point temperature). The R-T curve is linear, which is called positive temperature coefficient thermistor thick film circuit resistance effect. It not only has the general characteristics of thermistor, but also has the unique excellent performance which the general thermistor does not have because of its unique material composition and process, which greatly improves the control accuracy and sensitivity. It can realize multi temperature gradient setting and intelligent control.
