Message from a Representative
Ever since the Company's founding as Sanno Tokin Kogyosho (Plating industry) in 1958, our core business has been the precious metal surface treatment of electronic parts with the emphasis on connectors. Through our business activities, we have successfully accommodated the desires and demands of many customers.
We will continue to develop next-generation products that employ our plating technologies, aggregated over many years, and remain fully committed to meeting our customers' requirements and solving their manufacturing issues. By doing so, we aspire to win the trust of our customers as their partner of choice.
Technology You Want to Offer
Our surface treatment utilizes precious metals such as gold, palladium/nickel alloy, tin, silver, copper/tin etc, and we specialize in microprocessing including nickel barrier processing for selective plating as well as spot plating.
We are also currently developing technologies on hydrogen permeable films and silver plated acrylic resin particles with the use of surface treatment technologies.
