GB/T 17473.2-2008 "Test methods of presious metals pastes used for microelectronics - Determination of fineness"

This standard specifies a scraper method for determining the fineness of precious metal pastes for microelectronics. By using a Grindometer, the paste is placed on it and scraped, and the particle size is visually determined according to the location of the longitudinal stripes in the groove. This method is suitable for evaluating the particle size distribution of precious metal pastes to ensure their conformity and performance in the manufacture of microelectronic devices.
