ThunderClad 4SR
Extreme Low Loss and High Thermal Reliability Laminate and Prepreg
Core: TU-943SR; Prepreg: TU-943P SR
TU-943SR is an advanced material designed for high speed computing, telecommunications, radio frequency extreme low loss filed applications. TU-943SR electrical performance is competitive with PTFE-based, hydrocarbon-based extreme low loss materials, but capable for high layer count circuit board design with excellent thermal reliability.
TU-943SR laminates also exhibit excellent moisture resistance, improved CTE, superior chemical resistance, thermal stability, CAF resistance, and also compatible with modified FR-4 processes.
