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.
Main Applications
Consumer Electronics
Server, workstation
Automotive
Key Features
Lead Free process compatible
Excellent coefficient of thermal expansion
Anti-CAF property
Superior chemical and thermal resistance
Fluorescence for AOI
Moisture resistance
