Nickel colloid catalyst solution for electroless nickel or nickel alloy plating, and electroless nickel or nickel alloy plating method

After performing a preliminary adsorption promoting treatment by immersing a non-conductive substrate in a solution containing a surfactant, the non-conductive substrate is provided with a catalyst by means of a nickel colloid catalyst solution for electroless nickel plating, said nickel colloid catalyst solution containing (A) a soluble copper salt, (B) a reducing agent and (C) a colloid stabilizer, and electroless nickel plating is subsequently carried out. Since a catalyst is provided by means of a catalyst solution having excellent long-term stability after enhancing the catalytic activity by a preliminary treatment for promoting adsorption and the electroless plating is subsequently carried out, it becomes possible to obtain a uniform nickel coating film that is free from deposition unevenness. In cases where the present invention is applied to a nickel alloy plating method instead of the above-described nickel plating method, a nickel alloy coating film having excellent uniformity is able to be obtained.

Copper colloid catalyst solution for electroless copper plating and electroless copper plating method

The stability of a catalyst solution over time is notably improved by performing a preliminary adhesion-promoting treatment of soaking a non-electrically conductive substrate in a surfactant-containing solution and then applying a catalyst on the non-electrically conductive substrate with a copper colloid catalyst solution for electroless copper plating that contains (A) a soluble copper salt, (B) a reducing agent, (C) a colloid stabilizer, and (D) a specific sugar such as glucose, maltose, xylitol, sorbitol, etc. and performing electroless copper plating. Moreover, since the catalyst is applied and electroless plating is performed after catalyst activity has been increased by the preliminary adhesion-promoting treatment, the deposited copper film has an excellent appearance.

Copper colloidal catalyst liquid for electroless copper plating, electroless copper plating method, and production method for copper-plated substrate

According to the present invention, the temporal stability and the sustainability of catalyst activity of a catalyst liquid are both significantly improved since electroless copper plating is performed by subjecting a non-conductive substrate to an adsorption acceleration treatment (pretreatment) by bringing the non-conductive substrate into contact with a surfactant-containing liquid, and by applying a catalyst to the non-conductive substrate using a copper colloidal catalyst liquid that is for electroless copper plating and that contains (A) a soluble copper salt, (B) a reducing agent, (C) acolloidal stabilizer, and (D) a non-reducing oligosaccharide such as sucrose and trehalose. In addition, a deposited copper coating membrane will have excellent appearance since electroless copper plating is performed by applying a catalyst after the catalyst activity thereof is enhanced by the adsorption acceleration treatment (pretreatment).
