How to ensure the resistance stability of glass heating resistor paste at high temperatures?

Glass heating resistor pasteAs a special electronic material, it can stably convert electrical energy into thermal energy in high temperature environments and is widely used in the automotive, home appliance, medical, and industrial fields. However, the high temperature environment poses a serious challenge to its resistance stability. This article will delve into how to ensure the resistance stability of glass heating resistor paste at high temperatures through material selection and process optimization, using Advanced Institute (Shenzhen) Technology Co., Ltd. and Research Platinum brand resistor paste as examples.

1、 Material selection: Balance between high temperature stability and conductivity

Glass heating resistor paste is usually composed of conductive powder, insulating material, and adhesive. Material selection is crucial to ensure its resistance stability at high temperatures.

1. Metal based heating resistor pasteMainly composed of metal powders (such as silver, platinum, etc.), insulation materials, and adhesives, it has high conductivity and high temperature stability. The selection of metal powder directly affects the conductivity and high temperature resistance of the slurry. For example, silver is often used to manufacture high-performance resistor pastes due to its good conductivity and high temperature stability.

2. Ceramic based heating resistor pasteMainly composed of ceramic powder, insulation material, and adhesive, it has good insulation and high temperature stability. The addition of ceramic powder can improve the high-temperature resistance of the slurry, but may sacrifice some of its conductivity.

2、 Process optimization: dual guarantee of sintering and protective layer

1. Sintering process: After sintering at an appropriate temperature, the resistance paste forms a semiconductor with a certain resistance value. During the sintering process, the composition and temperature control of the slurry are crucial for the stability and uniformity of the resistance value. Advanced Institute (Shenzhen) Technology Co., Ltd. ensures the formation of a stable resistance layer during the sintering process of the slurry through precise sintering process control, which has excellent conductivity and heating performance.

   • Data comparison: Under the same conditions, usingAdvanced Institute (Shenzhen) Technology Co., LtdThe resistance change rate of the sintering process's resistance slurry has decreased by 20% compared to before optimization.

2. Protective layer design: To protect the stability of the resistor in high temperature environments, glass paste is usually printed onto the parts of the resistor and electrode wires that need to be protected using screen printing. After sintering, a thick film protective layer is formed. In addition, some models with high requirements for wear resistance will also add a hard thin film protective layer or anti-static layer on top of the thick film protective layer to enhance their high temperature resistance and anti-static performance.

   • Data comparison: After 1000 hours of continuous operation in a high-temperature environment, the resistance change rate of the resistor paste with a thick film protective layer added is only 5%, while the resistance change rate of the resistor paste without a protective layer added is as high as 20%.
