Gold plated - gold layer thickness greater than or equal to 0.5 micron; Heavy gold plated / Vermeil - gold layer thickness greater than or equal to 2.5 micron; Gold plated silver jewellery can still tarnish as the silver atoms diffuse into the gold layer, causing slow gradual fading of its color and eventually causing tarnishing of the surface ...
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.
Through-hole devices mounted on the circuit board of a mid-1980s home computer.Axial-lead devices are at upper left, while blue radial-lead capacitors are at upper right Close-up view of an electronic circuit board showing component lead holes (gold-plated) with through-hole plating up the sides of the hole to connect tracks on both sides of the board.
Gold–aluminium intermetallic have different properties from the individual metals, such as low conductivity and high melting point depending on their composition. Due to the difference of density between the metals and intermetallics, the growth of the intermetallic layers causes reduction in volume, and therefore creates gaps in the metal ...
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 ...
Gold shined in 2024, outperforming many other investment assets this year. Gold's trajectory can be traced back to late 2023, when its price surged to a record high of $2,135.39 per ounce due to ...

The MCX connector is also being used on at least some of the new generation of mostly inexpensive software-defined oscilloscopes and/or signal generators such as the DS212. This is a low frequency application, at most a few MHz bandwidth, so the electrical performance characteristics are relatively unimportant, however the small size would ...
