Surface Treatment Business Division

Offering surface treatment services

Nikko Shoji offers a total service for surface treatment processes, from system design through chemicals and other materials for plating solutions to plating devices. We are also actively involved in the development of platings with new functions and solutions to environmental issues. Our comprehensive approach has resulted in the development of electroless nickel plating solutions to make possible lead-free plating, and in various systems for the eco-friendly disposal of used solutions. In these ways, we offer prompt and timely support for our users’ environment-related needs.

Surface treatment agents for industrial use (functional plating/electronic parts)

We manufacture and sell chemical processing agents and materials for the production of electronic parts, including lead frames, printed circuit boards and connectors: we also provide technical support.

electroless nickel and gold plating process for PCB production electroless nickel plating electrolytes for general use lead-free and heavy metal free electroless nickel plating electrolytes tin and tin alloy plating electrolytes lead-free soft solder plating electrolytes (tin-zinc alloy plating electrolytes) electroless tin plating electrolytes gold and other precious-metal plating electrolytes electroless copper plating electrolytes pre-plating and post-plating processing agents (processing agents, anti-tarnish agents, de-plating agents) precious-metal salts (gold salt, silver salt, palladium salt, etc.)

Lead frames

Surface treatment agents for decorative use (decorative and anti-corrosive coatings)
We provide precious-metal plating electrolytes according to the type of decoration. plating electrolytes for gold, rhodium, ruthenium and palladium pre-plating and post-plating processing agents (processing agents, anti-tarnish agents, de-plating agents)	Surface finishing with chemical agents of a wide variety of metals

Reliable supply of fine chemicals

We also handles fine chemicals made of salts, particularly metallic salts, and their compounds. We employ advanced control technologies to regulate the purity, particle diameter and shape, density and so on of these substances —— at the microscopic level —— during the production process, and also utilize chemical mixing and compounding technologies to produce finished fine chemical products with a very high degree of reliability in terms of suitability to application and specific-function performance.

Powdered metallic salts

Fine chemicals

We provide metallic salts (in powder or solution) tailored to particular uses and functions.

• Nickel salts (nickel sulfamate, nickel carbonate)
• Tin salts (organic acid tin, activated stannous oxide, stannous sulfate)

Supplying related technological supports

Our service fields are not limited to surface treatment and fine chemicals: we supply various services with a wide range of technologies possessed by the Japan Energy group and the Nippon Mining & Metals group, which are manufacturers of oil and non-ferrous metal products, respectively under the umbrella of Nippon Mining Holdings, Inc.

Surface treatment processes using new or improved processing agents

We supply not only existing processes, but also new or improved processes to meet our clients’ requirements.

Materials

We supply metal anodes and inert anodes made of materials such as platinum and carbon, as well as other electrolytic materials and components.

Liquid waste processing (compliance with environmental regulations)

We recycle and process liquid and solid wastes to meet environmental regulations.

Equipment and facilities

We supply special chemical processing systems and agents to enhance the effectiveness of the plating process.
