    • PROBLEM TO BE SOLVED: To provide a plating pretreatment liquid capable of converting the surface of an aluminum substrate for a hard disk device into a surface suitable for electroless nickel plating, and a method for producing the aluminum substrate for the hard disk device using the plating pretreatment liquid.SOLUTION: The plating pretreatment liquid, which is used in a plating pretreatment for the production of the aluminum substrate for the hard disk device, has an iron ion concentration of 0.1 to 1.0 g/l and a nitric acid concentration of 2.0 to 12.0 wt.%. The plating pretreatment liquid is used in a pretreatment for a plating process in which the aluminum substrate for the hard disk device is subjected to electroless nickel plating. Consequently, the surface of the aluminum substrate for the hard disk device is converted into the surface that is suitable for electroless Ni plating, so that a smooth plating film surface is obtained by suppressing the formation of waves, nodules and pits in the plating surface when the electroless nickel plating is carried out in the plating step.
    • 要解决的问题:提供一种能够将用于硬盘装置的铝基板的表面转化成适合于化学镀镍的表面的电镀预处理液,以及用于制造用于硬盘装置的铝基板的方法 使用电镀预处理液。 解决方案:用于生产用于硬盘装置的铝基板的电镀预处理中的电镀预处理液的铁离子浓度为0.1〜1.0g / l,硝酸浓度为2.0〜 12.0重量%。 电镀预处理液体用于电镀工艺的预处理,其中用于硬盘装置的铝基板进行无电镀镍。 因此,用于硬盘装置的铝基板的表面被转换成适用于化学镀Ni的表面,从而通过抑制电镀表面中的波浪,结节和凹坑的形成来获得光滑的镀膜表面, 在电镀步骤中进行化学镀镍。 版权所有(C)2012,JPO&INPIT
