[Under development] Low-κ thermosetting tape for FPCs

Thermosetting tape for high-speed transmission FPCs with excellent low dielectric constant and bonding strength; capable of bonding at 180℃.

  • Product name
    D5200 series
  • Suitable use
    Interlayer adhesion of high-speed transmission FPCs
  • Features
    • Low transmission loss due to low dielectric constant
    • Existing FPC manufacturing equipment can be used because the tape thermally cures at 180℃.
    • This Novel formulation optimizes low dielectric constant with a high bonding strength. This technology enables the manufacture of highly reliable FPCs.
