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.
