Creat Ni+Ag plating by placing masking tape twice by using a laminator (1time)

Create a uniform and dense rough copper surface layer by applying oxide etching treatment to the bare copper surface.
Initial Cu1+ is oxidized,
and soluble Cu2+ induces
metal adhesion layer formation.
Growth and dissolution proceed simultaneously,
and the adhesion layer reaches maximum
thickness in an equilibrium state.
