In time management, gold plating is the phenomenon of working on a project or task past the point of diminishing returns.. For example, after having met a project's requirements, the manager or the developer works on further enhancing the product, thinking that the customer will be delighted to see additional or more polished features, beyond that which what was asked for or expected.
Electroless nickel immersion gold (ENIG or ENi/IAu), also known as immersion gold (Au), chemical Ni/Au or soft gold, is a metal plating process used in the manufacture of printed circuit boards (PCBs), to avoid oxidation and improve the solderability of copper contacts and plated through-holes.
Plating is a finishing process in which a metal is deposited on a surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for ...
There are several types of gold plating used in the electronics industry: [3] Soft, pure gold plating is used in the semiconductor industry. The gold layer is easily soldered and wire bonded. Its Knoop hardness ranges between 60 and 85. The plating baths have to be kept free of contamination. Soft, pure gold is deposited from special electrolytes.
We also know that George Richards Elkington (1801–1865), otherwise known for his patent for galvanic gilding and silver plating from 1840 patented at least one process of electrochemical coloring of metals (the American J.E .Stareck developed ten variants of his process around 1937). [10]

Chemical coloring of metals is the process of changing the color of metal surfaces with different chemical solutions. The chemical coloring of metals can be split into three types: electroplating – coating the metal surface with another metal using electrolysis. patination – chemically reacting the metal surface to form a colored oxide or ...
