Gold has a bright, reddish-yellow color in its purest form. It does not oxidize in the air at room temperature, so it remains very stable under normal conditions and its electrical conductivity is constant. It is one of the most common precious metals used in finishing.

Gold is corrosion resistant, which makes it a good finish for connector pins and electrical switch contacts.

Gold plating is used in parts and components across a wide range of main industries:

1. Medical applications: body implants
2. Energy: hydrogen fuel cell Bipolar plates
3. Semiconductor: microelectronic chips
4. Aerospace & defense
5. Telecommunications and other more

ROYAL Technology supplies turnkey coating solutions for manufactures who are looking for a reliable team for long term cooperation.

Robust design, large batches, fast cycle, flexible coating processes are the basic design concepts ROYAL Team has been pursuing.

Design Advantages

1. Energy saving: compact design and molecular pumps are applied
2. High target utilization up to 40% with planar sputtering cathode
3. Sputtered Au gold film’s thickness is controllable
4. One-Touch operation system

PVD Gold sputtering deposition

1. When comes to glass, metal alloys etc. Substrates material, the bonding layer is essential to enhance substrate and Aufilm adhesion. Royal Technology has developed a range of matured coating recipes based on different applications, support our customers with professional advice.
2. The roughness (RMS – root mean square) < 40Å is expected for most of the applications. For certain scanning probe applications a lower roughness might be required, generally 1.5 ~ 4 nm.
3. Gold sputtering layer surface purity: a clean surface is required for applications that employ gold surface modifications. Depending on the PVD process used, level of vacuum in the system, original purity of the gold source (over 99.99% generally)
