- Introduction to Isola 370HR Material
Isola 370HR PCB is a high-performance FR-4 system with a 180°C glass transition temperature (Tg), specially designed for multilayer printed circuit boards (PCBs) that demand maximum thermal performance and reliability. Manufactured using a unique high-performance multifunctional epoxy resin and reinforced with electrical-grade (E-glass) glass fabric, this material outperforms traditional FR-4 in thermal performance and offers lower expansion rates while maintaining excellent processability similar to conventional FR-4.
In addition to its superior thermal properties, Isola 370HR excels in mechanical strength, chemical resistance, and moisture resistance, meeting or exceeding the performance of traditional FR-4 materials. It also features laser fluorescing and UV blocking capabilities, ensuring maximum compatibility with Automated Optical Inspection (AOI) systems, optical positioning systems, and photoimagable solder mask imaging. Renowned as a top choice for sequential lamination designs, Isola 370HR is a versatile solution for high-reliability PCB applications.
