High Density Interconnection(HDI) Multilayer Board is using materials and processes developed on our own. As a product attaining both higher density and higher reliability, it is able to realize downsizing, weight reduction and functional improvement of electronic equipment.


  • The stable production of the minimum line/space 75/75μm is possible because conductor thickness is uniform.
  • By using our base materials, we can respond quickly to our customer needs by the halogen-free property and the high frequency property.
  • Achieving high elastic modulus by using prepreg in build-up layers.
