When plating connectors, a thin metallic layer is evenly applied across the contact surface as a way to boost durability, resistance to corrosion, and conductivity.
A variety of different platings can be used to achieve connectors that are reliable, cost-effective and optimised to perform well. Notably, the demand for precious metal chemicals used in the plating industry is increasing and is forecast to reach more than $283 million in the EU alone.
Electroless nickel plating
Nickel-based plating processes are an excellent alternative to noble metal based coating processes, particularly as they’re more cost-effective and highly durable.
Electroless nickel plating can improve the wear resistance of connectors and boost overall thermal stability, which is critical to a number of applications in the automotive and aerospace sectors. More information about the application of nickel-based plating can be found on the websites of specialists such as https://www.swmf.co.uk/surface-coatings/electroless-nickel-plating/.
Silver plating
Another popular plating metal is silver, as it offers excellent conductivity that is particularly suitable for high-frequency and high-power applications. However, as silver can tarnish in humid environments, it is often combined with palladium which reduces tarnishing while only reducing its conductivity power by 15%.
Gold plating
The popularity of gold plating is set to continue, as it is reliable and offers excellent conductivity. Gold plating is extremely expensive when compared to its alternatives, which is why it’s usually only reserved for critical areas of contact. Its price has also prompted industry experts to find alternative methods that deliver high quality results, which is why the applications of electroless nickel plating are continuing to evolve.
