Description

technical field [0001] The invention belongs to the technical field of electronic equipment production, and in particular relates to a resistance paste and a preparation method. Background technique [0002] Resistor is a commonly used electrical component with a wide range of applications, such as integrated circuits and chips. However, with the rapid development of integrated circuits and chips, current resistors have many shortcomings and cannot meet the needs of integration. Resistors Slurry has become a direction to solve this problem. Therefore, it is an urgent problem to find a resistance paste that can eliminate the above disadvantages. [0003] Electronic paste is the basic material for the manufacture of thick film components. It is a paste made of solid powder and organic solvents that are mixed uniformly by three-roll rolling. Existing resistance pastes are often difficult to balance resistance performance and mechanical performance. Therefore, the development...
