Gold Plating

Gold plating is a method of depositing a thin layer of gold onto the surface of another metal, most often copper or silver (to make silver-gilt), by chemical or electrochemical plating. This article covers plating methods used in the modern electronics industry; for more traditional methods, often used for much larger objects.

Mspecs offers rack and barrel gold plating which is currently employed in numerous industries including the medical, telecommunications, and aerospace.

Gold plating has excellent electrical and thermal conductivity, offers exceptional solderability and is a superb reflector of infrared radiation.  In addition, gold does not oxidize or chemically react under normal conditions.  Gold plating is an exceptional choice for numerous engineering requirements where electrical conductivity (especially at low voltages), solderability and corrosion resistance are design requirements.
