1、 Basic requirements for heat resistance performance

1. high temperature stability

   Resistance paste must maintain stable conductivity and physical properties in high temperature environments. Usually, it is required that the resistance paste does not undergo significant changes in resistance value, structural deformation, or failure at high temperatures (such as above 200 ℃).

2. Thermal shock resistance

   Resistance paste should be able to maintain good stability and reliability in rapidly changing temperature environments, such as rapidly cooling from high temperature to low temperature or rapidly heating from low temperature to high temperature. Thermal shock resistance is the evaluation of the performance stability of resistive slurries during high-temperature cycling use.

3. Matching of thermal expansion coefficient

   The thermal expansion coefficient of the resistance paste when heated should match the coated substrate to avoid delamination, cracking, and other problems caused by inconsistent thermal expansion.
