Wear Resistance Platinum Coated Titanium Electrodes PCB Gold Plating Anodes
Platinum coated Titanium Anodes for PCB Gold Plating
Plating a thin layer of nickel, tin, gold or alloy coating on electronics parts improves the electrical conductivity. For example the Ni/Au plating process is utilized in the PCB industry to improve the electrical performance of contact area with the purpose to obtain a low electrical contact resistance; good wear resistance and protection against oxidation (corrosion). Precise Heater special anodes can supply both Platinised anodes and Iridium Mixed Metal Oxide (MMO) coated Titanium anodes. The optimum anode coating depends on the client specific application requirements. Platinised anodes supplied by Precise Heater special anodes are already being widely used in these processes by various major manufacturers.
Advantages:
·Stable performance and long functional lifetime
·Low bath voltage and homogeneous current distribution
·Less additive consumption
·Environmentally friendly
·Low total cost of ownership
