This standard specifies in detail the requirements, test methods, inspection rules, and labeling, Encasement, transportation, storage, and order contents of ruthenium-based thick film resistive pastes. The scope of application is ruthenium-based thick film electrocathode pastes for thick film hybrid integrated circuits and resistive networks. A series of related documents are cited in the document, including the Measuring method for current noise of fixed resistors, the general specification for film fixed resistor networks for electronic equipment, etc. In this standard, ruthenium-based thick film resistive pastes are defined as a paste composed of ruthenium dioxide powder, ruthenium salts, inorganic additives, and organic carriers that satisfies the printing or coating characteristics.
