1. Introduction of RO4835 and 370HR
Rogers' RO4835 laminate offers enhanced stability at high temperatures and is more resistant to oxidation than other hydrocarbon materials. RO4835 laminates share similar electrical and mechanical properties with RO4350B laminates and are designed for high frequency performance and cost-effective circuit fabrication. It uses standard epoxy/glass (FR-4) processes and is competitively priced.
RO4835 laminates are a low loss material that offer low cost circuit fabrication. These laminates are available with Rogers proprietary LoPro Reverse treated copper foil, ideal for applications requiring low insertion loss.

Isolar's 370HR laminates are made using a patented high performance 180°C Tg FR-4 multifunctional epoxy resin system that is designed for multilayer Printed Wiring Board (PWB) applications where maximum thermal performance and reliability are required. They are manufactured with high quality E-glass glass fabric for superior Conductive Anodic Filament (CAF) resistance. 370HR provides superior thermal performance with low Coefficient of Thermal Expansion (CTE) and the mechanical, chemical and moisture resistance properties that equal or exceed the performance of traditional FR-4 materials.
