MCL-HE-679G (Type S)

Halogen Free, Low Dielectric Constant, High Heat Resistance Multilayer Material

Product form

CCL MCL-HE-679G (Type S)
Prepreg GHA-679G (Type S)

Applications

  • Network applications.
  • High-frequency parts. (filters, VCOs, etc.)

Features

  • Enables lower transmission loss than MCL-HE-679G with lower dissipation factor.
  • High Tg and superior heat resistance for soldering. (Suitable for lead free process)
  • CTE in Z-direction is 30% lower than that of standard FR-4.
  • Achieved UL 94V-O flammability standard without using any compound which includes halogen, antimony or red phosphorous.
