• Electrolytic gold systems
• Commodity components
We are the worldwide market leader in precious metals for
the semiconductor industry.
Immersion gold – Supermex 200 Series
Excellent complement to standard electroless nickel
deposits. Processes are ready-to-use, cyanide-free,
with a pH of 7.0 and low gold consumption. Deposits
Information on cyanide-based immersion processes is
available upon request.
Electroless gold – Supermex 800 Series
This cyanide-free plating solution is suitable for thick and
uniform plating of fine and complicated patterns. Features
of the processes are neutral pH, high plating speed and
long bath life (with suitable replenishment).
Noble metals (Pt, Pd, Rh and Au) can be plated directly.
Base metals need to be catalyzed by standard methods
(cyanide or cyanide-free immersion gold).
Electroless palladium – Pallamex 800
This replenishable, weakly acidic, cyanide-free process is
suitable for putting down a solderable, corrosion-resistant
layer of pure palladium on nickel where a photo resist is
applied and to reduce the overall thickness of wire-bondable
gold. Further details are available upon request.
