ISOLA: LEAD-FREE FR4 EPOXY
370HR High Tg/ High Td Lead-Free Processable Laminate

370HR is a high Tg, high Td 180C glass transition temperature (Tg) FR-4 system for multilayer printed wiring board (PWB) applications where maximum thermal performance and reliability are required. 370HR laminate and prepreg products are manufactured with a unique high performance multifunctional epoxy resin, reinforced with electrical grade (E-glass) glass fabric. This system provides improved thermal performance and low expansion rates in comparison to traditional FR-4 while retaining FR-4 processability. In addition to this superior thermal performance the mechanical, chemical and moisture resistance properties all equal or exceed the performance of traditional FR-4 materials. The 370HR system is also laser fluorescing and UV blocking for maximum compatibility with automated optical inspection systems (AOI), optical positioning systems and photoimageable soldermask imaging.

185HR High Performance Resin System

185HR is a proprietary, high performance resin system with a Tg >170°C for multilayer Printed Wiring Board (PWB) applications where maximum thermal performance and reliability are required.
185HR laminate and prepreg products are manufactured using Isola’s patented technology, reinforced with electrical grade (E-glass) glass fabric. This system delivers a 340°C decomposition temperature, a lower Z-axis expansion and offers lower loss compared to competitive products in this space.

The 185HR system is also laser fluorescing and UV blocking for maximum compatibility with Automated Optical Inspection (AOI) systems, optical positioning systems and photoimageable solder mask imaging.
