TU-865S CTI≥600 material is made of epoxy resin and E-glass fabric. It’s a halogen free material and design to have both features for harsh environment, high reliability application and superior electrical performance at the same time. TU-865S achieves flammability class of UL94V-0 by incorporating phosphorous and nitrogen compounds. The material is compatible with the AOI process and exhibit the UV-block characteristic. TU-865S P is prepreg designed for use with TU-865S laminate for making multilayer printed wire boards. TU-865S is also available for single/double sided application. This series of green materials eliminate the use of halogenated resins with excellent performance due to the potential hazardous effects from the environmental concerns. These products are suitable for boards that need to survive severe thermal cycling, or to experience excessive assembly work. TU-865S laminates also exhibit superior chemical resistance, dimensional stability and moisture resistivity for lead free soldering assembly and CAF resistance.
