Isola Terragreen

TerraGreen laminate materials exhibit exceptional electrical properties which are very stable over a broad frequency and temperature range. TerraGreen is engineered for such high performance applications as power amplifier boards for 4G LTE base stations, internet infrastrucure and cloud computing. TerraGreen features a Dielectric Constant (Dk) that is stable between -55C and 125C, up to 20 GHz.

TerraGreen is a lead-free assembly mareial and is easy to process. This high-performance material utilizes a short-lamination cycle; the product is easy to drill, does not require plasma desmear and the prepreg shelf life is similar to FR-4 materials. TerraGreen is suitable for high-layer count, high-speed digital, backplanes and is compatible with Isola’s FR-4 materials for hybrid designs. TerraGreen meets UL 94 V-0 and is halogen free.
