Low Dielectric Constant, Low Dissipation Factor,
High Heat Resistance Multilayer Material <MCL>
MCL-FX-2 · GFA-2 <prepreg>Inquiry
- 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.
