Note: Your request will be directed to Isola Group

The TerraGreen from Isola Group is an RF/Microwave Laminate Material that meets the IPC-4103/17, UL 94 V-0 and E41625 standards. It has a dielectric constant of 3.45 that is stable between the temperature range from -55 and 125°C, for up to W-band. The material has a dielectric loss of 0.0032 which was measured by the Bereskin Stripline test method. It has a thermal conductivity of 0.63 W/m-K and reaches dielectric breakdown at 45.4 kV.

The TerraGreen is available in laminate sheet/panel form, prepreg roll/panel form, copper foil or copper weight type, and is compatible with Isola’s FR-4 materials for hybrid designs. It requires a short-lamination cycle, is easy to drill, does not require plasma desmear, and the prepreg shelf life is similar to FR-4 materials. The laminate material is ideal for application in digital backplanes (high-layer count, high-speed) and for power amplifier boards for LTE base stations, internet infrastructure and cloud computing.
