The World's No.1 Micro Electronic Terminal Manufacturer.

Our company has a world-class mass-production system for headed parts, employing 2000 in-house automated processing machines. By using plastic working technology for metal wire we have accumulated in the roughly 50 years since our founding, we can handle virtually any part that can be manufactured through header processing, from micro pins with a wire diameter of φ100μm or less, to large headed parts.
We have achieved the top market share in the world in PGA terminals for the CPUs of mobile devices, laptop computers, servers, and other systems. In this field, we produce over 10 billion units a month, and we have always maintained stable high quality.
By exploiting the ultra-small and minute metal header processing technology we have accumulated in this way over many years, we offer the ultra-small terminals and micro pins, such as the copper pillars, copper posts, and copper pins, used in application processors for smartphones and other devices. 


  • Copper / Cu pillar pins
    Cu Pillar Pin is a cutting-edge material for high-density mounting....

  • Compared with solder balls or the layered plating system, Cu pillars have the following advantages for use.

    • The installation of Cu Pillar Pin can be done at a lower cost compared to the layered plating.
    • The mounting time of Cu Pillar Pin is shorter compared to the layered plating, therefore reducing mounting cost.
    • The Cu Pillar Pin, compared to the layered plating, is able to lower the running cost as there is no need to manage plating solutions.
    • Cu Pillar Pin is able to produce a high aspect ratio with a narrower pitch when compared with the solder balls and the layered plating.
