Red plague is an accelerated corrosion of copper when plated with silver. After storage, damage or use in high-humidity environment, cuprous oxide forms on the surface of the parts. The corrosion is identifiable by presence of patches of brown-red powder deposit on the exposed copper. [1]
Immersion silver plating (or IAg plating) is a surface plating process that creates a thin layer of silver over copper objects. It consists in dipping the object briefly into a solution containing silver ions.
Copper electroplating sees widespread usage in the manufacture of electrical and electronic devices, owing to copper's high electrical conductivity – it is the second-most electrically conductive metal after silver. [20] Copper is electroplated onto printed circuit boards to add metal to the through holes and fabricate the board's conductive ...
Electroless deposition is an important process in the electronic industry for metallization of substrates. Other metallization of substrates also include physical vapor deposition (PVD), chemical vapor deposition (CVD), and electroplating which produce thin metal films but require high temperature, vacuum, and a power source respectively.

Copper Thunderbolt 4 cables up to 1.0 m (3.3 ft) are passive cables, while longer cables must integrate active signal conditioning circuitry. 2 m (6.6 ft) maximum is the length of active cables available from most brands, including CalDigit, [41] Cable Matters, [42] et al., while Apple are currently the only company that offers a 3 m (9.8 ft ...
HDMI 2.0, referred to by some manufacturers as HDMI UHD, was released on September 4, 2013. [110] HDMI 2.0 increases the maximum bandwidth to 18.0 Gbit/s. [110] [111] [112] HDMI 2.0 uses TMDS encoding for video transmission like previous versions, giving it a maximum video bandwidth of 14.4 Gbit/s. This enables HDMI 2.0 to carry 4K video at 60 ...
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.
