Auto-HR is a proprietary, high-performance resin system with a glass transition temperature (Tg) >170°C for multilayer Printed Wiring Board (PWB) applications where maximum thermal performance and reliability are required.
Auto-HR laminate and prepreg products are manufactured using Isola’s patented technology and are reinforced with electrical grade (E-glass) glass fabric. This system delivers a 340°C decomposition temperature (Td) and a lower Z-axis expansion compared to competitive products. Auto-HR will be available in the Asia Pacific and European market only, with specific constructions to provide superior performance at a competitive cost.
The Auto-HR system is also laser fluorescing and UV blocking for maximum compatibility with Automated Optical Inspection (AOI) systems, optical positioning systems and photoimagable solder mask imaging. Auto-HR is available in limited thicknesses, including 0.014″, 0.028″, 0.035″, 0.042″.
