I-Speed™ is a proprietary high-performance 180°C (DSC) glass transition temperature (Tg) FR-4 system for multilayer printed wiring board (PWB) applications where maximum thermal performance and reliability are required.
I-Speed™ is a low-loss (Df 0.007), high-speed material system. It has a very good thermal performance and thermal stability, with excellent storage life for finished PCBs.
I-Speed laminate and prepreg products are manufactured with Isola’s patent pending high performance multifunctional 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. 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.
The I-Speed system is also laser fluorescing and UV blocking for maximum compatibility with automated optical inspection systems (AOI), optical positioning systems and photoimagable solder mask imaging.
