NEAP

What is NEAP?

  • "NEAP" means Non Etch Ag Prep.
  • "NEAP" is the Non Etch Ag Prep onto leadframe surface.
  • Enhance Ag and Cu adhesion to mold compound through Ag Oxide to improve MSL performance.
  • Low cost MSL solution.

A-NEAP

B-NEAP

B-NEAP
  • NEAP MSL performance on Ag plated surface and copper plated surface are good as it uses Ag oxide to enhance mold compound adhesion.
  • No delamination found at MSL 1 for NEAP, on 5x5 QFN.
  • NEAP sample visual appearance is slightly different than normal plated leadframe (slight silverish).
