Thick film resistor paste It is a paste-like substance that is formed by uniformly mixing the conductive phase, glass phase and carrier in a certain proportion through a three-roll machine. It meets the printing requirements and is a key material used in the production of thick film integrated circuits, electronic components, and heaters. It is divided into precious metal, base metal and polymer thick film resistor pastes. Among them, the precious metal thick film resistor paste is the most widely used due to its stable performance and reasonable price.

The commonly used resistive pastes for stainless steel thick film heating elements include ruthenium-based thick film resistive paste and Ag/Pd palladium silver thick film resistive paste. Both materials have their own advantages and disadvantages, and the specific choice depends on the application scenario. The pastes mainly focus on rheological properties, dispersibility, electrical performance and stability. These parameters are somewhat similar to some parameters of the positive and negative electrode powders of lithium-ion batteries after the slurry is prepared, such as viscosity and solid content, etc. These parameters are related to the feasibility of heating element manufacturing, process yield and product reliability.
