TU-662F

Mid-Tg and High Thermal Reliability Laminate and Prepreg
Core: TU-662 F; Prepreg: TU-66P F

TU-662 F laminate / prepreg materials made of high quality woven E-glass coated with the epoxy resin system, which provides the laminates UV-block characteristic, and compatibility with automated optical inspection (AOI) process. These products are suitable for boards that need to survive severe thermal cycles, or to experience excessive assembly work. TU-662 F laminates exhibit excellent CTE, superior chemical resistance, and thermal stability for lead free soldering assembly with general CAF resistance.
