Precision Gold Plating for Industrial Performance

At Smart Microns, we specialise in high-quality, precision 24-karat gold plating for ferrous, cuprous, aluminium, steel and a variety of other materials used in industrial applications. Using Nano Tech Gold Deposition (NTGD) technology, we provide gold plating thicknesses ranging from 0.3 to 15 microns.
In our gold electroplating process, we deposit a thin layer of gold onto the surface of another metal, most often copper or silver. An electric current is passed through an electrolyte solution containing dissolved gold ions, allowing them to adhere to the component surface and form a protective gold coating.
Our gold plating offers excellent electrical and thermal conductivity, exceptional solderability, infrared reflectivity and resistance to oxidation. These properties make it suitable for applications where conductivity, solderability and corrosion resistance are essential, particularly across the aerospace, electrical and electronics industries. Backed by our experienced staff and quality assurance team, we finish every component to exact specifications and fine tolerances, with both functional and aesthetic finishes.
