It is an electrolytic tin plating that prevents thin plate and flat plate fine press products from sticking together.
Heat sinks, heat spreaders, and lead pins for semiconductors and various electronic components are often made from copper or iron materials that have been processed through pressing and header processing. In this case, nickel plating (Ni) is mainly used for rust prevention, while silver plating (Ag) is utilized to ensure solder wettability. On the other hand, tin plating, which is inexpensive and provides both rust prevention and wettability, is sometimes avoided because products can easily stick together, even though it would be desirable to use. Our company can provide functional Sn plating with rust prevention and solder wettability at a low cost, without worsening yield due to sticking. This is a technology for application development based on the establishment of mass production facilities tailored to customer needs.

Company information
The slogan is "Challenge the Impossible." We are a technology development-oriented company that broadly develops unique surface treatment technologies to meet the special needs required for essential low-voltage components (related to electricity, electronics, and semiconductors), high-voltage components (such as high-voltage connectors), and insulating components. Additionally, we have established a support system that incorporates functional surface treatments, which we have cultivated since our founding, as our core technology, along with processes such as pressing, heat treatment, painting, and assembly. We will continue to deliver consistent Yuden-sha brand technologies and products to the world. *We support online business meetings.
