Solución de chapado en oro, sin electrodos, contenido de metal ≈ 3,7 g/l, Thermo Scientific Chemicals

Prior to plating, we recommend that you thoroughly clean the surface of the object to be plated. First, use a brush and a mild detergent to scrub the surface and then rinse thoroughly with purified water. Next, use a dilute hydrochloric (HCl) acid solution to remove any surface oxides and rinse thoroughly with purified water.

The gold plating solution can be kept in a glass beaker directly heated on a hot plate. The pH can drop with use, and we recommend adjusting the pH to the optimal range by adding small amounts of concentrated ammonium hydroxide.

Assuming 50% of the gold is used, the coverage will be approximately 4096 cm²/L (635 in²/L or 2400 in²/gal) for an average thickness of 5 microinches of gold.

The deposition rate for the Gold plating solution, electroless, metal content≈3.7g/L is 0.2-0.3 microinches/minute for a maximum thickness of 7-8 microinches in 30 minutes at 160°F (71°C). The thickness of gold can be increased to up to 15 microinches at a higher temperature of 175°F (80°C).

The operating conditions for the Gold plating solution, electroless, metal content≈3.7 g/L are as follows:

• pH 5.0-5.5
• Agitation preferred
• Time: at least 15 minutes
• Temperature: 60-71°C (140-160°F)
