Copper (Cu) leadframe for Open cavity (air cavity) QFN semiconductor packages.

Check chart below for available plating thicknesses.

About G1 (NiPdAu) plating thickness for ceramic package:
  • G1 : Rich Gold plating. Excellent wire bondability. Good reflow SMT.

    • About G3 (NiAu) and G4 (NiPdAu) plating thickness:
  • G3 : Rich Gold plating. Excellent wire bondability. Good reflow SMT. Occasionally subject to black pad phenomena.
  • G4 : Gold plating looks richer. Excellent wire bondability. Good reflow SMT. Seldom subject to black pad phenomena.

    • About G5, G6 and G7 End of Life (EOL):
  • G5 : Gold plating looks richer. Excellent wire bondability. Good reflow SMT. Occasionally subject to black pad phenomena.
  • G6: Thin Gold plating appears silver in color. Excellent bondability. Superior reflow SMT solderability.
  • G7: Gold plating appears gold in color. Excellent bondability. Superior reflow SMT solderability.
