摘要
The thickness of the thin separation, also the primary purpose of providing the flake copper powder for a conductive paste having a powder (粉體) characteristics that can be used for forming such fine electrode or a circuit and a method of manufacturing the same. ; To achieve this object, in the separation of copper powder in a flake copper powder, flake screen by the plastic deformation of the powder and granular copper powder, a laser diffraction scattering type particle size by weight cumulative particle diameter D 50 is less than 10㎛ by the distribution measuring method, a laser weight cumulative particle diameter by a diffraction scattering type particle size distribution measuring method D 10, D 50, D 90, a laser diffraction scattering type particle size, the value of the grain size SD / D 50 shown with the standard deviation SD of the distribution measured by the distribution measuring method 0.55 or less, and also employs a flake copper powder, and the like, it characterized in that the value represented by D 90 / D 10 of 4.5 or less. This is made possible flake copper powder to be compressed to produce high-energy ball mill using media business with a fine particle size and to stabilize the plastic deformation by making over the flakes.
