Features
- Fit for multilayer build-up core with excellent flexural modulus of 30GPa
- Excellent in PTH reliability,twice as much as FR-4 CCL,with Low CTE property of 26ppm/℃
- 35%～70% less heat shrinkage than FR-4 CCL
- Prepreg (ES-3305S) is laser-drillable.
- Excellent in heat release property
- Excellent in moisture resistance with half water absorption property of FR-4 CCL
- Excellent in price/performance
