Hitachi Chemical Co. America, Ltd.

Low Dielectric Constant, Low Dissipation Factor, High Heat Resistance Multilayer Material <MCL>

MCL-FX-2 ・GFA-2 <prepreg>

Transmission loss in the GHz band can be reduced to about 50% of our standard FR-4. Standard glass fabric (E-glass) specification makes drilling and cutting workability as high as that of our standard FR-4. It is suitable for network applications, super computer, measuring equipment, high-frequency modules and antenna application.

Features

  • Transmission loss in the GHz band can be reduced to about 50% of our standard FR-4.
  • Dk and Df are small.
  • General-purpose glass fabric (E-glass) specification makes drilling and cutting workability as high as that of our standard FR-4.
  • High Tg, low water absorption and excellent heat resistance.
