Industry Leading, Standard Loss, Thermally Robust Epoxy Laminate and Prepreg
Isola 370 heures is the industry's âbest in classâ lead-free compatible product for high-reliability applications across a wide range of markets.
Isola 370 heures laminates and prepregs, Conçu par polyclad, are made using a patented high performance 118.0.°C Tg FR-4.... multifunctional epoxy resin system that is designed for multilayer PCB applications where maximum thermal performance and reliability are required. Isola Manufacturing Isola 370 heures laminates and prepregs with high quality E-glass glass fabric for superior Conductive Anodic Filament (CAF) resistance. Isola 370 heures provides superior thermal performance with low Coefficient of Thermal Expansion (CTE) and the mechanical, chemical and moisture resistance properties that equal or exceed the performance of traditional FR-4 materials.
Isola 370 heures is used in thousands of PWB designs and has proven to be best in class for thermal reliability, CAF performance, ease of processing and proven performance on sequential lamination designs.
