Electroless nickel immersion gold - Wikipedia

Electroless nickel immersion gold (ENIG) is a metal plating process used in the manufacture of printed circuit boards (PCBs), to avoid oxidation and improve the solderability of copper contacts and plated through-holes.It consists of an electroless nickel plating covered with a thin layer of gold, which protects the nickel from oxidation.The gold is typically applied by quick immersionIamgold - Wikipedia,The Yatela Mine gold mine in Mali was operated by joint-venture partner AngloGold Ashanti, each with a 40% working interest. Mining activities had ceased in 2013, though processing continued into 2016. The Tarkwa mine and Damang mine in Ghana were operated by Gold Fields. Iamgold secured a 19% stake in the mines with the acquisition of Repadre Capital in 2002 but sold their interests to Gold,An Overview of Immersion Gold ENIG Surface Finish for,2019-10-11· Advantages of Immersion Gold Finish. Although ENIG is an expensive surface finish technology, still it is popular due to the following reasons: Immersion gold has strong chemical properties. These properties include impressive wettability, surface planarity, coplanarity, and long shelf life. The properties are contributed by nickel and gold layer. In

New Immersion Gold Technology for Uniform Au Thickness,

Our new immersion gold technology can effectively reduce the galvanic effect by introducing a new chemical system. The electropotential differences were minimized among pads with various surface areas or connected to different inner-layer copper areas thus providing a uniform gold deposition. Meanwhile, the plated Au thickness can be steadily increased from less than 1Electroless Nickel / Immersion Gold Process Technology for,,Electroless Nickel / Immersion Gold Process Technology for Improved Ductility of Flex and Rigid-Flex Applications By: Kuldip Johal and Hugh Roberts - Atotech USA Inc.

China Immersion gold PCBs,Mutilayer PCBs 40900234 is supplied by Immersion gold PCBs,Mutilayer PCBs manufacturers, producers, suppliers on Global SourcesWhat is Che Ni/Au or ENIG? - Technical Terms by,Che Ni/Au or ENIG is a chemical process, applied after solder mask that adds 3-6µm Nickel before adding between 0.065µm and 0.10µm Gold onto the copper. To protect the solder pads for oxidation and to make the copper better solder able we can apply ENIG, Electro less Nickel Immersion Gold or also called Che Ni/Au, chemical nickel gold or also called soft gold.Comparison of ENIG and ENEPIG on techniques,,Newly-developed immersion gold technology not only reduces corrosion on nickel surface, but helps decreasing cost as well. Compared with immersion gold solution (pH=4.5-5.5) of last generation, new-generation immersion gold solution is close to be neutral with a pH value in the range from 7.0 to 7.2. Neutral liquid performs best in stopping hydrogen ion corroding nickel

Control of Electroless Nickel Baths - ECI Technology |

One possible drawback of the ENIG finish is the probable nickel corrosion during immersion gold deposition – a defect commonly referred to as “black nickel” or “black pad” [1]. Black pads typically cause solderability failure and therefore need be avoided.
