TU-862T

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

TU-862T Hi-Tg halogen free materials are made of High Tg epoxy resin and E-glass fabric. Unlike conventional FR-4 material using brominated resin as flame retardant, TU-862T /TU-862P T achieves flammability class of UL94V-0 by incorporating phosphorus and nitrogen compounds in the materials. The materials are compatible with the AOI process and exhibit the UV-block characteristic. TU-862P T is designed for use with TU-862T for making multilayer printed wire boards. TU-862T 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-862T laminates also exhibit superior chemical resistance, thermal stability for lead free soldering assembly and CAF resistance than conventional High Tg materials.
