  • Patent number: 10780530
    Abstract: A solder ball according to the present invention contains 0.2 to 2.2% by mass of Zn, and a balance of Sn, and has a spherical diameter of 0.1 to 120 ?m and a yellowness (b*) in an L*a*b* color system of 2.70 or more and 9.52 or less. An oxide film is formed by performing aging treatment.

  • Patent number: 10722965
    Abstract: A solder-ball-supplying method, a solder-ball-supplying device and a solder-bump-forming method, which are flux-less and capable of being also applied to electrodes having a fine pitch. A substrate on which a resist with openings is positioned on electrode(s), which has a diameter of 10 through 30 ?m, of the substrate is prepared. Next, plural solder balls SBL each having a grain diameter of 1 through 10 ?m are shaken down to the opening(s) of the resist from a hopper and filled therein. Next, by sliding and moving a squeegee on an upper surface of the resist along X-Y direction, the solder balls SBL shaken down to the resist other than the openings are scrapped and removed and the solder balls SBL in the openings and around them are pushed into the openings by the squeegee.

  • Patent number: 10446838
    Abstract: Cycle characteristics of a nonaqueous secondary battery are to be improved. An active material including: a first active material that contains a nano silicon produced by heating a layered polysilane represented by a composition formula (SiH)n and having a structure in which multiple six-membered rings formed from silicon atoms are connected; and a second active material that contains a graphite, is used in a negative electrode. With this, expansion and contraction due to stress during charging and discharging can be mitigated, and thereby cycle characteristics improve.

  • Patent number: 10347910
    Abstract: A nano silicon material having reduced amounts of oxygen (O) and chlorine (Cl) contained therein is provided. The nano silicon material contains fluorine (F) and nano-sized silicon crystallites. Generation of a layer in which oxygen (O) and chlorine (Cl) are present is suppressed due to the presence of fluorine (F), so that a decrease in the moving speed of lithium ions is suppressed. In addition, due to the presence of fluorine (F), the concentrations of oxygen (O) and chlorine (Cl) are reduced, so that reaction thereof with lithium ions is suppressed.

  • Patent number: 9876232
    Abstract: A positive electrode active material layer comprises a coating layer for coating at least part of surfaces of positive electrode active material particles. The coating layer comprises alternate layers of a cationic material layer containing a cationic material having a positive zeta potential and an anionic material layer containing an anionic material having a negative zeta potential under neutral conditions, and a material layer having a zeta potential of opposite sign to that of the positive electrode active material particles is bonded to the surfaces of the positive electrode active material particles. The coating layer is thin and uniform, and has a high strength for bonding to the positive electrode active material particles, so the coating layer suppresses direct contact of the positive electrode active material particles and an electrolytic solution even when a nonaqueous secondary battery is used at a high voltage.
