Halogen Free Pcb

Halogen FreeConcerns regarding the health and safety of halogenated flame retardants in PWB applications dates to the early 1990s when it was discovered that under certain circumstances highly toxic dioxins and furans could be released during the (incomplete) combustion of PWBs that use brominated flame retardant. While it is not yet legislated that electronic component suppliers must remove brominated and chlorinated flame retardants from their materials, Isola nonetheless offers a variety of high performance non-halogenated prepregs and laminates to meet the industry's ever increasing performance needs.Isola FeaturesHalogen-free meeting IPC/JEDEC J-STD-709 for Bromine and Chlorine content Lead-free assembly compatible Enhanced signal integrity Enhanced CAF performance Typical Applications: Automotive Mobile and Wireless Devices Signal Integrity Servers High End ComputingIS300MDis a proprietary high performance, low-Dk, low-loss, halogen-free material specifically designed for the high-end mobile applications.TerraGreen® laminate materials is engineered for such high-performance applications as power amplifier boards for 4G LTE base stations, internet infrastructure and cloud computing.DE156is a type FR-4 base material, meeting the /94 requirements for halogen free.ParameterFR4 Standard FR4 High-TG FR4 Halogen-free FR4 KF Polimid TG ℃≧135≧170≧140≧135≧230CET-z ppm/℃6045455020Permittivity ER bei 1MHZ4.64.84.74.73.4Electrical Strength KV/mm45555045125Surface Resistivity MΩ10^610^710^710^710^6Tracking Resisitance CTI VPLC3PLC3PLC3PLC1/PLC0TD Value ℃301345360310Peel Strenth N/mm1.1-1.61.21.41.61.6Flammability Class UL-94V0V0V0V0V0Standard IPC-4101IPC-4101IPC-4101IPC-4101IPC-4101IPC-4204 Details
