Preplated NiPdAu Cu leadframe for Open cavity (air cavity) QFN semiconductor packages.
Available in three plating thicknesses.

About G5 , G6 and G7 plating thickness:
  • G5 : Thick gold plating looks richer. Excellent wire bondability. Good reflow SMT, but occasionally subject to black pad phenomena.
  • G7: Medium gold plating appears gold in color. Excellent bondability. Superior reflow SMT solderability.
  • G6: Thin gold plating appears silver in color. Excellent bondability. Superior reflow SMT solderability.
