Conductive copper pasteIt is a special material widely used in the electronics industry. This material is used for the manufacturing of circuit boards, coating of contacts and connectors, and other aspects.
Composition and preparation of conductive copper paste
The main components of conductive copper paste are copper powder and organic components. The process generally includes four steps: batching, mixing, mortar preparation, and printing. In the process of ingredient preparation, it is necessary to control different proportions based on the fineness of the powder. After the ingredients are completed, put the raw materials into the mixer for mixing. After the mixture is formed, the next step is mortar preparation, during which some solvents are added to make the mixture more uniform. Finally, conductive copper paste is produced through printing.
