CAC/CSC Copper - Press plate constructions

CAC® (Copper Aluminum Copper) and CSC® (Copper Steel Copper) are thin Aluminum or Steel press plates with one important difference. They are embedded between two Copper foils with the sensitive sides (shiny) protected from airborne contaminants or prepreg dust.

  • Facilitates the use of ultrathin
    (> 6 μm) or reverse-treated Copper foils
  • Prevention of wrinkles or damage to the
    copper foil during installation
  • Improved thermal conductivity leads to
    faster heating rate
  • Capacity improvement through thinner
    press sheets
  • Lower labor costs through faster
    bildup process
