The board is supplied with Gerber RS-274-X artwork data and is manufactured in compliance with the stringent IPC-Class-2 acceptance standard, ensuring consistent and reliable production quality for a worldwide market.
Material Advantages of Isola 370HR
The core of this PCB's reliability is the Isola 370HR material, a high-performance Tg 180°C FR-4 epoxy system. It offers exceptional thermal resilience, with a Td of 340°C and a T288 delamination time of 30 minutes. Its low Z-axis CTE (45ppm/°C) enhances reliability during thermal cycling. Electrically, it provides a stable Dk of 4.04 at 2GHz and a Df of 0.021 at 2GHz. Key attributes include superior resistance to Conductive Anodic Filament (CAF), a UL94-V0 flammability rating, and low moisture absorption (0.15%), making it a proven choice for multilayer applications requiring maximum durability.
