Gold

Overview

With our state of the art gold operation, we pride ourselves on quality, service, short lead times and competitive pricing. We utilize gold pure to 99.9% and hardened to a purity of 99.7% containing cobalt to harden gold deposits, and we specialize in working with your engineers to provide process engineering and prototyping R&D for the most difficult and challenging applications such as;

  • Selective gold plating, fixture design and fabrication.
  • Difficult substrates: Tellurium copper, Kovar, Hastalloys, Monels, Inconels etc.
  • Custom-engineered and fabricated racking fixtures for delicate applications.
  • Abilities to Barrel plate small components with rotational barrel mesh down to 105 microns (.004”) using controllable rotational speeds.
  • Vibratory barrel capabilities for fragile parts and parts requiring high throw into small holes and recess areas. Basket sizes 3.5 and 6 inches.
  • Determining and engineering the proper gold deposit for the application.

Finishing options available:

  • RoHs
  • Extremely small and delicate part finishing options
  • Rack plating
  • Barrel plating
  • Vibratory finishing of soft & hard gold substrates

Finishing options available:

  • ASTM B 488: Hard Gold and Soft Gold.
  • Mil-G-45204: Hard Gold and Soft Gold.
  • AMS 2422
  • AMS 2425
  • An overwhelming majority of customer specifications not listed.

Common Substrates:

  • Copper Alloys (includes leaded brass & other alloys)
  • Heat treated Beryllium Copper
  • Stainless Steels
  • Aluminum alloys
  • Phosphorous Bronze
  • Steel and high strength alloys

Industries Served:

  • Electronics
  • Telecommunications
  • Medical
  • Aerospace

In many cases, a under plate of nickel is required over copper and copper alloys including brass to prevent diffusion of copper migrating to the gold plate. These requirements are covered extensively in ASTM B 488, page 7 Section X5.2.4 and page 8 Section X6. Nico meets those underplate requirements with ROHS Compliant Electrodeposited Nickels per QQN- 290 B, plus Medium and High Phosphorous Electroless Nickels per ASTM B-733-04, Mil C-26074 E and AMS 26074 B. Quality Assurance: Our baths are tested for purity and hardness. All solutions are SPC tracked and controlled in our on-site Lab, using our state of the art lab software.
