DF,HS Series

DF, HS series are die bonding films, necessary for high performance packages such as stacked MCP and BGA. We have a top share in the die bonding film market. The uniform die bonding layer can be obtained by a simple laminating process.

Features of DF Series

  • Obtainable a uniform bonding layer without void.
  • Excellent workability and storage stability.
  • Excellent reflow crack resistance.

Features of HS Series

  • Excellent stress reduction by low elastic modulus.
  • Excellent gap filling capability of substrate.
  • Applicable for thicker film.
