Gold Plating Services from Precision Plating
The process of Gold Plating requires the application of a thin layer of gold onto the exterior surface of another metal. At Precision Plating, our specialization in electroplating allows us to offer gold plating services for orders of all sizes. Our gold finishing capabilities include: Continuous Reel to Reel Plating, Rack Plating, Barrel Plating, Vibratory Plating or Prototype Plating, depending on your application.
Gold Plating is valued for its physical properties. As a noble metal, gold has a natural ability to resist corrosion and oxides which can form on the surface of other non-noble metals. Corrosion and oxides can create electrical conductivity issues resulting in poor performance or shortened product life-cycles, which this process can help avoid.
Precision's services use either hard gold or soft gold. Gold's harness is measured on the Knoop scale, which is a way to test microhardness for brittle and thin materials. The type of gold used for plating depends on the application. For example, hard gold is ideal when corrosion resistance is necessary to the job, whereas soft gold is best suited for high reliability solder applications.
Hard gold is an alloy of 99.7% gold and 0.3% of a hardening agent, most commonly either nickel or cobalt. Gold plating is used as an electrical or electronic contact finish because it is a noble metal that does not oxidize or chemically react in corrosive environments. Hard gold has a Knoop hardness between 130 – 200 and is used where electrical conductivity (especially very low current applications), solderability and/or corrosion resistance are important design requirements. When compared to soft gold, hard gold proves superior contact wear resistance.
Hard Gold Plating Specifications: ASTM B488, MIL-G-45204, MIL-DTL-45204
Pure gold is naturally soft because it has little to no grain refiners or additives to make the deposit hard. Soft gold is 99.9% pure gold and has a Knoop hardness between 91-115, so it is pliable and is easier to solder than hard gold. Soft gold is typically used in lead frame wire bonding applications and high reliability solder applications where hard gold would not be appropriate.
