High Tg Lead Free Multi-layer Printed Circuit Board Built on TU-768 Core and TU-768P Prepreg
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
General Description
TU-768 / TU-768P laminate / prepreg are made of high quality woven E-glass coated with the epoxy resin system, which provides the laminates with 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-768 laminates exhibit excellent CTE, superior chemical resistance and thermal stability plus CAF resistance property.
