0.8mm TU-768 High Tg PCB Board Black Soldermask White Silkscreen ENIG

Product Specification

Sharing a new RF PCB made of TU-768 material. The TU-768 laminate by Taiwan Union is a high-Tg (glass transition temperature) and high thermal reliability laminate designed to meet rigorous performance requirements. It is accompanied by TU-768P, a matching prepreg for enhanced functionality. These laminates and prepregs are constructed using high-quality woven E-glass coated with an epoxy resin system, offering UV-block characteristics and compatibility with automated optical inspection (AOI) processes. The TU-768 series is well-suited for applications that demand resilience against thermal cycles and extensive assembly work. Notably, TU-768 laminates exhibit exceptional CTE (coefficient of thermal expansion), superior chemical resistance, thermal stability, and CAF (conductive anodic filament) resistance properties.

Key Features:
- Dk (dielectric constant) of 4.3 at 10GHz
- Dissipation factor of .0023 at 10GHz
- CTE x-axis of 11-15 ppm/°C, CTE y-axis of 11-15 ppm/°C
- Coefficient of thermal expansion matched to copper
- Decomposition Temperature (Td) of 350 °C TGA
- Tg (glass transition temperature) of 180°C
- High thermal reliability with T260 >60 min, T288>15 min, T300 >2 min

Benefits:
- Compatible with lead-free processes
- Excellent coefficient of thermal expansion for stability
- Anti-CAF (conductive anodic filament) property for improved reliability
- Superior chemical and thermal resistance
- Fluorescent properties enable AOI (automated optical inspection)
- Resistant to moisture-related issues
