  2. Berg connector - Wikipedia

    en.wikipedia.org/wiki/Berg_connector

    The plastic connector housing is most often white, as shown (TE Connectivity / AMP 171822-4), but black is also common. Other colours are rarer. The part numbers used for the female contact pins depends on the detailed design, the surface coating (for example tinned or gold plated) and the form of supply.

  3. Plating - Wikipedia

    en.wikipedia.org/wiki/Plating

    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 ...

  4. Electroless nickel immersion gold - Wikipedia

    en.wikipedia.org/wiki/Electroless_nickel...

    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.

  5. Titanium nitride - Wikipedia

    en.wikipedia.org/wiki/Titanium_nitride

    Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.

  6. Tinning - Wikipedia

    en.wikipedia.org/wiki/Tinning

    Hot tin-dipping is the process of immersing a part into a bath of pure molten tin at a temperature greater than 450 °F or 232 °C. Tinplate made via hot-dipped tin plating is made by cold rolling steel or iron, pickling to remove any scale , annealing to remove any strain hardening , and then coating it with a thin layer of tin .

  7. Electrical connector - Wikipedia

    en.wikipedia.org/wiki/Electrical_connector

    The number of times a connector can connect and disconnect with its counterpart while meeting all its specifications is termed as mating cycles and is an indirect measure of connector lifespan. The material used for connector contact, plating type and thickness is a major factor that determines the mating cycles. [35]

  8. Gold plating - Wikipedia

    en.wikipedia.org/wiki/Gold_plating

    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 ...

  9. Solder alloys - Wikipedia

    en.wikipedia.org/wiki/Solder_alloys

    On gold surfaces gold-indium intermetallics tend to be formed, and the joint then fails in the gold-depleted zone and the gold-rich intermetallic. [37] Less gold dissolution and more ductile than lead-tin alloys. [12] Good thermal fatigue properties. Pb 60 In 40: 195: 225 [16] Pb: No: In40. Low gold-leaching. Good thermal fatigue properties. Pb ...
