TU-862 HF

High Tg Halogen Free Material
Core: TU-862 HF; Prepreg: TU-86P HF

TU-862 HF/TU-86P HF Hi-Tg halogen free materials are made of epoxy resin and E-glass fabric. Unlike conventional FR-4 material using brominated resin as flame retardant, TU-862 HF/TU-86P HF achieves flammability class of UL94V-0 by incorporating phosphorous and nitrogen compounds in the materials. The materials are compatible with the AOI process and exhibit the UV-block characteristic. TU-86P HF is designed for use with TU-862 HF for making multilayer printed wire boards. TU-862 HF is also available for single/double sided application. This series of green materials are designed to eliminate the use of halogenated resins due to the potential hazardous effects from the environmental concerns. These products are suitable for boards that need to survive severe thermal cycles, or to experience excessive assembly work. TU-862 HF laminates also exhibit superior chemical resistance, thermal stability for lead free soldering assembly and CAF resistance.
