ISOLA 370HR Material Introduction
ISOLA 370HR is a high-performance 180°C Tg FR-4 material system developed for multilayer printed wiring boards demanding superior thermal performance and long-term application reliability. Manufactured with proprietary multifunctional epoxy resin reinforced with E-grade glass fabric, it provides enhanced thermal endurance and reduced thermal expansion versus conventional FR-4, while retaining standard FR-4 process compatibility.
Its mechanical robustness, chemical durability and moisture resistance meet or exceed standard FR-4 performance benchmarks. Equipped with laser fluorescence and UV-blocking properties, 370HR achieves full compatibility with AOI inspection, optical positioning and photoimageable solder mask processes. It is also well qualified for complex sequential lamination multilayer projects.
Core Material Features
Superior Thermal Performance: 180°C Tg (DSC), 340°C Td (TGA @ 5% weight loss), low CTE for structural reliability; 60min T260 endurance, 30min T288 endurance
Environmental Compliance: Fully RoHS compliant
UV Blocking & AOI Compatibility: Improves fabrication and assembly efficiency with high inspection precision
Outstanding CAF Resistance: Restrains conductive anodic filament growth to extend service lifespan
Easy Fabrication: Matches standard FR-4 fabrication workflow for mass production
Diversified Material Options: Various core thicknesses, prepreg forms, glass fabrics and copper foils available; customized copper thickness is acceptable
Full Industry Qualification: Compliant with IPC-4101D specifications, UL certified (File No. E41625), UL MCIL program approved
