- By chemical or
electro-chemical plating, a thin layer of gold deposit onto the
surface of another metal, mostly copper or silver (to make
silver-gilt).
- Gold plating of silver
is used in the manufacture of jewelry.
- In electronics, to
provide a corrosion-resistant electrically conductive layer on
copper in electrical connectors and in printed circuit boards
gold plating is employed.
- In the process of hard
gold plating, Gold is anodically dissolved in a potassium cyanide
solution to produce a concentrate of gold potassium cyanide which
is used for preparing the plating solution concentrate by adding
other chemicals. The concentrate, on dilution, can be used for high
speed 50 micro meters per hour, hardness 150 kg per sq. mm gold
plating on various components used in
electronics and other industries.
- Soft gold plating is
especially for semi-conductor devices. Soft gold baths are based on
KAu(CN)2, KH2PO4, potassium citrate and trace amounts of additives.
- The process of plating
has proven to be versatile, for example the gold plating of
stainless steel or copper electrodes associated with the fuel cell
industry.
- In certain cases, 24
Karat gold plating is applied to some grades of stainless steel.
- The gold plating
density may vary between 11.3mg/in 2/5m to 12.45mg/in 2/5m, which is
the upper range and used for a highly fine grained gold plating
grain.
- Gold is generally
specified as a contact coating for low level signal voltage and
current applications.
- High connector
reliability can be achieved by gold coating on the electrical
contacts. Gold, when applied to contact interface, has the ability
of providing a stable and low contact resistance over the operating
life of most applications.
- When a gold is plated
on titanium metal by the chemical displacement
method, plating bath comprising a soluble gold salt, a salt for
attacking the metal oxide dioxide and a stabilizing agent.
- Plating is carried out
to provide long lasting decorative finishes and in some cases to
improve electric contact.
- More economic where
wear resistance is required as in watch, pen and plumbing fixtures
in such cases thin deposit of pure gold deposits over bright nickel.
- A readymade gold
plating salt is available in market in which the required proportion
of the chemicals are mixed which can also be utilized for the
purpose.
- Plating of gold is
often found in microelectronic devices for air-bridges, heat-sinks
and gold bumps for flip-chip techniques.
