SENSITIZING SOLUTION FOR ELECTROLESS PLATING, AND ELECTROLESS PLATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a sensitizing solution for electroless plating, which can easily dissolve an Sn compound therein without using an acid and can be used for a long period of time without impairing the uniformity of the metal-plated film. SOLUTION: The sensitizing solution for electroless plating includes the Sn compound and a solvent. The solvent includes 10 vol.% or more of a water-soluble alcohol. An electroless plating method includes a pretreatment step of immersing an article to be plated into a pretreatment solution, and a plating step of immersing the article to be plated after having been pretreated into a plating solution. The sensitizing solution for the electroless plating is used as the pretreatment solution. COPYRIGHT: (C)2010,JPO&INPIT
