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.
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]
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 .
Premium posts are hard-drawn beryllium copper alloy plated with a 0.000025 in (630 nm) of gold to prevent corrosion. Less-expensive posts are bronze with tin plating. 30 gauge (~0.0509mm 2 ) silver -plated soft copper wire is insulated with a fluorocarbon that does not emit dangerous gases when heated.
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 ...
Gold offers high liquidity overall, but physical gold isn't as liquid as digital gold. You'll need to find a buyer if you want to cash in on your investments or head up to your local pawn shop to ...
Demonstration of ultrasonic wedge bonding of an aluminium wire between gold electrodes on a printed circuit board and gold electrodes on a sapphire substrate, reverse bonding order. The main classes of wire bonding: Ball bonding; Wedge bonding; Compliant bonding; Ball bonding usually is restricted to gold and copper wire and usually requires heat.
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 ...
