The industry's top level of low transmission loss is achieved by pursuing the further low-profiling while maintaining the same level of the adhesion as H-VLP.

Feature

  • By the ultra-fine roughening and the special surface treatment, the lower transmission loss than H-VLP is realized.

Typical application

  • Information communication equipment such as the high-end router and the server.
  • Substrate for an antenna in a communication base station
  • Substrate for the millimeter wave radar
