What characteristics Isola 370HR laminates have? Let’s learn something about it and we can know what kind of PCBs will use Isola370HR laminates.
370HR is a high performance 180°C glass transition temperature(Tg) FR-4 system for multilayer Printed Wiring Board (PWB)applications where maximum thermal performance and reliabilityare required. 370HR laminate and prepreg products aremanufactured with a unique high performance multifunctionalepoxy resin, reinforced with electrical grade (E-glass) glass fabricThis system provides improved thermal performance and lowexpansion
rates in comparison to traditional FR-4 while retainingFR-4 processability.
In addition to this superior thermal performance, the mechanicachemical and moisture resistance properties all equal or exceedthe performance of traditional FR-4 materials. The 370HR systemis also laser fluorescing and UV blocking for maximum compatibilitywith Automated Optical inspection (AOl) systems, optical positioningsystems and photoimagable solder mask imaging. 370HR has proven to be best in class for sequential laminationdesigns.
