  • CORE BALL AND SEMICONDUCTOR PACKAGE INCLUDING THE SAME
    Publication number: 20250226344
    Abstract: A core ball includes a core that is metal or plastic, a first metal layer formed on a surface of the core, a second metal layer formed on the first metal layer and including a tin (Sn)—bismuth (Bi) binary alloy, and a third metal layer formed on the second metal layer and including a single metal of tin (Sn), wherein a melting point of an alloy of a material forming the second metal layer and a material forming the third metal layer is 150° C. or less.

  • METHOD OF MEASURING CHANGE RATE OF CLOSED PORE, METHOD AND SYSTEM FOR MANUFACTURING ELECTRODE PLATE, AND ELECTRODE PLATE
    Publication number: 20250167198
    Abstract: In a method of measuring a closed-pore change rate, the method includes: measuring, by small-angle X-ray scattering (SAXS) and Brunauer, Emmett, and Teller (BET), a specific surface area in a first powder state and a specific surface area in a second powder state with respect to pores created in a powder state; measuring, by SAXS and BET, a specific surface area in a first electrode plate state and a specific surface area in a second electrode plate state with respect to pores created in an electrode plate state; and calculating a closed-pore change rate of an electrode plate based on the specific surface areas in the first and second powder states and the specific surface areas in the first and second electrode plate states.
