What is The Isola I-Speed ® PCB Material?
Isola I-Speed® is a Tg 180°C FR-4 resin system for multilayer PWB applications where maximum thermal performance and reliability are required. I-Speed® laminate and prepreg products are manufactured with Isolas’ patentable high performance multi-functional resin system, reinforced with electrical grade (E-glass) glass fabric. This system delivers a 15% improvement in Z-axis expansion and offers 25% more electrical bandwidth (lower loss) than competitive products in this space. These properties coupled with superior moisture resistance at reflow, result in a product that bridges the gap from both a thermal and electrical perspective.
The I-Speed® resin system is laser fluorescing and UV blocking for maximum compatibility with Automated Optical Inspection (AOI) systems, optical positioning systems and photo imagable solder mask imaging. In today’s electronics manufacturing landscape, materials are expected to deliver not only high thermal and mechanical performance but also cost efficiency and compatibility with advanced manufacturing processes. I-Speed® high speed laminates are engineered to meet these demands, offering a balanced combination of thermal stability, electrical performance, and process flexibility for a wide range of high performance applications.
In addition, I-Speed® supports multiple lamination cycles and is fully compatible with HDI technology. This makes them ideal for complex, multi-layered PCB designs. Their lead free assembly compatibility ensures compliance with modern environmental and manufacturing standards.
