FR408HR

408HR is a proprietary high performance 230C (DMA) glass transition temperature (Tg) FR-4 system for multilayer printed wiring board (PWB) applications where maximum thermal performance and reliability are required. 408HR laminate and prepreg products are manufactured with Isola's patentable high performance multifunctional resin system, reinforced with electrical grade (E-glass) glass fabric. This system delivers a 30% improvement in Z axis expansion and offers 25% more electrical bandwidth (lower loss) than competitive products in this space. When these properties are coupled with its superior moisture resistance at reflow you have a product that bridges the gap from both a thermal and electrical perspective.
