GOLD PLATING PROCESS

AUROSHINE BRIGHT GOLD	Gold Potassium Cyanide Auroshine Conducting salt Auroshine brightener Temperature pH Cathode movement Anodes Current Density Voltage	12 g/l 65 g/l 20 ml/l Room to 65 ºC 3.8 – 4.2 Continuous Platinised Titanium or Graphite. 0.5 – 1.0 A/dm2 1 – 4 Volts	Used widely for gold plating of printed circuit boards, contacts, connectors, jewellery and electronic components. Good wear resistance and throwing power.
AUROSHINE SG (STRIKE GOLD)	Gold content Auroshine SG Make-up Temperature pH (electrometric) Agitation Anodes Cathode current density Plating time Auroshine SG Replenisher	1 – 3 g/l Full strength. 50 - 55º C 3.4 – 3.6 Cathode rod movement Platinised Titanium 0.8 – 1.2 A/dm2 1 – 2 mins. One ml for one gm. Gold consumed.	The process is used as a Gold strike before main Gold plating. Promotes adhesion on nickel and nickel alloys and on other base metals. Deposit is golden yellow colour. Deposit is 99.98% pure. Used for electronic and decorative applications.
AUROSHINE – 2N	Gold content AUROSHINE 2N MAKE-UP CONCENTRATE Temperature pH (electrometric) Cathode Current Density Agitation Anode Auroshine 2N Replenisher Rate of plating	4 – 6 g/l Full strength. Room 3.2 – 3.6 0.8 – 1.2 A/dm2 Cathode rod movement Platinised Titanium or Graphite. One ml for one gm. Gold consumed One micron in 7.0 mins at 1A/dm2	Designed to produce non tarnish uniform bright Gold deposit. Used for plating jewellery articles plated deposit is 23.0 carat having hardness around 200 – 240 HV.
AUROSHINE – 3N	Gold content AUROSHINE 3N MAKE-UP CONCENTRATE Temperature pH (electrometric) Cathode Current Density Agitation Anode Auroshine 2N Replenisher Rate of plating	4 – 6 g/l Full strength. Room 3.2 – 3.6 0.8 – 1.2 A/dm2 Cathode rod movement Platinised Titanium or Graphite. One ml for one gm. Gold consumed. One micron in 7.0 mins at 1A/dm2	Designed to produce uniform bright Gold deposit of 23.5 carat. Used for plating all jewellery articles to deposit 1.0 – 2.0 micron. Over which Gold flash is given for getting rich gold colour. Produces hard Gold deposit having hardness around 160 – 200 HV.
AUROSHINE – CC	Gold content AUROSHINE CC MAKE-UP CONCENTRATE Temperature pH (electrometric) Cathode Current Density Anode Plating rateAuroshine CC Replenisher	6 – 16 g/l Full strength. 20 – 50 ºC 3.2 – 3.8 0.3 – 1 A/dm2 Platinised Titanium 2.5 micron in 1.5 mins at 1A/dm2 One ml for one gm. Gold consumed.	Hard acid gold process using Cobalt as an alloying metal. Produces bright deposit having good hardness. Suitable for plating connectors printed wiring boards, contacts and switches. Suitable for vat and barrel plating.
