Thick film technology is formed by screen printing and sintering. The material used in thick film printing is a special material - paste
1. For printability, the dye needs to have a certain viscosity, and the viscosity decreases with the shear force applied by the squeegee, and it is thixotropic.
2. Functional properties: such as properties required as a resistor, conductor, dielectric, etc.
3. Process compatibility: The paste should have good adhesion to the substrate. When various pastes are used in combination, different pastes will not have adverse reactions with each other or with the substrate during the entire process.
