Electroless Gold Plating
Get Price Quote
Electroless means that the process used to plate the gold onto a surface is not the traditional electroplating cell having electrodes and an external power supply. Electroless gold is deposited from a solution purely as the result of the reaction of chemicals in the bath. The electroless plating bath is comprised of several of the same items found in an electrolytic gold plating bath, but it also includes chemicals (reducing agents) to provide electrons for the reaction and other chemicals (chelating agents and stabilizers) to control the reaction so that it can be predictable and controllable as a manufacturing process. Why Does It Matter Which Process is Used to Plate?Is the Deposit the Same?To plate a part using an electrolytic process, every surface to be plated must be connected electrically so that it can act as the cathode in the plating cell. This becomes difficult for many products but especially for electronic circuits that generally need to have electrically isolated surfaces to be functional. Over the course of the development of the electronics industry it has become common practice to design in connections to tie different surface metal patterns together just for plating and then to remove these connections after plating. The manufacturing inefficiencies of this are obvious but a greater problem is the restriction this places on the final performance and circuit density of the component. Using electroless gold plating, circuits can be designed and fabricated in their final configuration. This saves the manufacturer several steps but more importantly it allows the circuit design to place primary consideration on optimum circuit performance and minimum circuit size. The electroless gold deposit is identical to an electrolytic pure gold deposit (i.e., Mil-G-45204 C Type III or ASTM B488 Type 1 hardness code A) in essentially every way; thickness, purity, hardness, grain size, density and color. The primary difference from an electrolytic gold deposit is it's second distinct advantage... improved thickness distribution. Electrolytic plating creates deposits that have thickness variations resulting primarily from the shape of the electrical field between the cathode surfaces and the anode. These deposits are thicker on corners and edges and surfaces where the distance to the anode is shortest. They are also thinner in the middle of surfaces, inside of holes and on surfaces facing away from the anode. Electroless plating completely eliminates this source of variation. Electroless gold plated deposits are uniform in thickness around corners, on both sides of a part, even on the inside walls of small holes that may be very deep.

3 - 5 Per Sq. in.
Our plating capabilities have recently expanded to include Rose Gold plating. It provides a more distinctive, opulent polish to your jewelry. All precious and non-precious metals can be plated in hard gold, which is a long-lasting finish. For a quote or further information, please give us a call. With the help of our unique Rose Gold electroplating solution, existing gold plate may be rapidly coated with a deep rose gold hue. You need a stainless anode. An alloy of copper and gold is called electro-deposited rose gold. There is very little gold present, and it is not measured in karats. The copper, which is far tougher than gold, won't corrode because there is enough gold in it. That's why well-plated rose gold holds up so nicely. We plate thickly enough for jewelry.

MIL-G-45204 Gold Plating, Electrodeposited Type I 99.7 % gold minimum; hardness grade A, B, or C. Gold plating used for general-purpose, high-reliability electrical contacts, solderability, and wire wrap connections. Type II 99.0 % gold minimum; hardness grade B, C, or D. A general-purpose, wear-resistant gold. It will not withstand high-temperature applications because the hardening agents in the gold plating will oxidize. Type III 99.9 % gold minimum; hardness grade A only. Gold plating for semiconductor components, nuclear engineering, thermocompression bonding, and high-temperature application. Gold Plating & Gold Electroplating - purity and coating thickness: Co-deposited impurities can make soldering more difficult, and for this reason high purity gold plating is preferred. Soldering requirements are best achieved when gold electroplating coatings range between 0.00005 and 0.0001 inch (50 and 100 micro inches) thickness. Gold Plating & Gold Electroplating - Hardness Grades: 1. 90 knoop, maximum2. 91-129 knoop, inclusive3. 130-200 knoop, inclusive4. 201 knoop, minimum Gold over silver is not recommended for electronics hardware: Gold Plating - Underplate RecommendationsGold Electroplating - When gold is applied to a copper rich surface such as brass, bronze, or beryllium copper, metal ions from these base metals will diffuse into the gold layer and degrade its hardness and non-oxidizing properties. An antidiffusion underplate such as nickel (electroless or sulfamate) should be applied to prevent this. We recommend electroless nickel under gold where part flexure of deformation is not expected and a bight finish is desirable. Where part flexure or deformation is expected, we recommend sulfamate nickel as the underplate because of its higher ducility.
