Yamaichi Electronics started here.
Yamaichi Electronics started with vacuum tube sockets and has been providing the world with cutting-edge products that meet the needs of the times. We developed and started selling IC sockets earlier than any other manufacturers in Japan. We were one of the first companies in the world to put connectors on sale for small memory cards. We also boast the world’s top share of the burn-in socket market for testing semiconductors. In this way, Yamaichi Electronics has grown to become a leading global provider of IC sockets for use in semiconductor inspection processes and connectors for electronic and electrical equipment, based on the technology and creative spirit it has cultivated since its foundation.
