  • Patent number: 10882088
    Abstract: A hard rolled-copper foil which, when heated and laminated on an insulating resin base material, can exhibit excellent bend-resistance characteristics without increasing a final reduction ratio, which, being not prone to develop rolling marks, can maintain a low surface coarseness and can therefore be preferably used in a flexible printed wiring board having excellent high-speed transmission characteristics, which is not prone to softening at room temperature, and which provides excellent operation efficiency and foil passing property when being processed into a flexible printed wiring board after having been stored. A hard rolled-copper foil in which a crystal orientation density in a copper orientation is not less than 10, and a crystal orientation density in a brass orientation is not less than 20.

  • Publication number: 20200264086
    Abstract: This invention relates to a method of evaluating powder for lamination shaping by stable criteria. In this method, it is evaluated whether powder for lamination shaping can be spread into a uniform powder layer in the lamination shaping, wherein the powder is evaluated using, as a flowability of the powder, an adhesive force of the powder calculated from a failure envelope obtained by a shear test. The shear test is conducted by a powder rheometer, and the adhesive force is obtained from the relationship between a normal stress and a shearing stress at the powder rheometer. If the adhesive force is 0.450 kPa or less, the powder is evaluated to be spread into a uniform powder layer in the lamination shaping. Furthermore, if at least one of that the 50% particle sin of the powder obtained by a laser diffraction method is 3 to 250 ?m and that the apparent density of the powder is 3.5 g/cm3 or more is satisfied, the powder is evaluated to be spread into a uniform powder layer in the lamination shaping.

  • Publication number: 20200254517
    Abstract: This invention relates to a method of evaluating a squeegeeing property of powder for lamination shaping by stable criteria. In this method, the squeegeeing property is evaluated using at least a satellite adhesion ratio of the powder and an apparent density of the powder. The satellite adhesion ratio is the ratio of the number of particles on which satellites are adhered to the number of all particles. If the satellite adhesion ratio is equal to or less than 50%, and the apparent density is equal to or more than 3.5 g/cm3, the squeegeeing property is evaluated as that the powder can be spread into a uniform powder layer in the lamination shaping. Furthermore, if the 50% particle size of a powder obtained by a laser diffraction method is 3 to 250 ?m, the squeegeeing property is evaluated as that the powder can be spread into a uniform powder layer in the lamination shaping.

  • Publication number: 20200147682
    Abstract: This invention provides a copper powder to which tin (Sn) is added such that a high-density laminated and shaped product can be obtained by a laminating and shaping method using a fiber laser as a heat source by appropriately reducing the electrical conductivity of copper, so a laminated and shaped product having a high density and a high electrical conductivity can be obtained. That is, this invention provides a copper powder for lamination shaping in which a tin element is added to pure copper. Desirably, the copper powder contains 0.5 wt % or more of the tin element. More desirably, the copper powder contains 5.0 wt % or more of the tin element. When the product has an electrical conductivity sufficient as a copper product, the copper powder desirably contains 6.0 wt % or less of the tin element. Furthermore, no element other than the tin element is desirably added to the copper powder.
