Features

  • Halogen free material for environmental concerns.
  • CTE (Z-direction) is 50% lower than that of our standard FR-4.
  • Elastic modulus is 20% higher than that of our standard FR-4. Even thin laminate has less warpage and deflection.
  • Superior heat resistance for soldering (suitable for lead free process).
  • Suitable for fine patterning with 1/4 surface roughness of our standard FR-4 pattern possible.
