ThunderClad 3E

Very Low Loss and High Thermal Reliability Laminate and Prepreg
Core: TU-933E; Prepreg: TU-933P E

ThunderClad 3E / TU-933E is an advanced material designed for high speed computing, telecommunications, radio frequency super low loss filed applications. ThunderClad 3E’s electrical performance is competitive with hydrocarbon-based very low loss materials, but capable for high layer count circuit board design with excellent thermal reliability.
ThunderClad 3E laminates also exhibit excellent moisture resistance, improved CTE, superior chemical resistance, thermal stability, CAF resistance, and also compatible with modified FR-4 processes.
