FR408HR laminate and prepreg products are manufactured with Isola’s patented 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.
FR408HR has superior moisture resistance at reflow, result in a product that bridges the gap from both a thermal and electrical perspective. The FR408HR system is also laser fluorescing and UV blocking for maximum compatibility with Automated Optical Inspection (AOI) systems, optical positioning systems and photo-imagable solder mask imaging.
