The ENIG (Electroless Nickel Immersion Gold) process has been widely used for fine pitch SMT (Surface Mount Technology) and BGA (Ball Grid Array) packaged devices due to its benefits including excellent solderability, high uniformity and substantial legibility throughout the packaging process.
The thickness of the Nickel and Gold is controlled in the range of 4-6 µm nickel and 40-60 nm gold. Measurement tools and methods The thickness uniformity of the Nickel and Gold layer was investigated by X-ray fluorescence measurement (XRF). The cross section samples were prepared by epoxy casting, grinding and polishing.
Electroless nickel does not have the high temperature properties of pure nickel, e.g. high temperature oxidation resistance. Pure nickel has a melting point of 1455°C but the phosphorus content of electroless nickel has a very sig-nificant effect on its melting point, as shown in Figure 2. The

The difficulty of an electroless nickel / immersion gold process is in its complexity. The multiple pre-treatment steps, plating steps and process control levers to consider are the reason why ENIG has been a historically difficult process to handle. Affinity ENIG 2.0 was developed using process control methodology and the result is a more ...
Decorative surface finish and method of forming same US8632864; A decorative metal finish for a part with a non-conductive surface where the non-conductive surface is lightly roughened to improve its adherence capabilities. A thin metal layer is electrolessly deposited on the lightly roughened surface to provide a bright durable metal finish on the non-conductive surface.
On an electroless-nickel immersion gold (ENIG) finish, forensic analysis ensures the nickel, which is the base plating before the gold is deposited, is performing according to the spec sheet. Also, it pinpoints infinitesimally minute fractures within solder joints. Minute solder pinholes are not visible at the 300X to 400X magnification level.

This Class 205 is considered to be an integral part of Class 204 (see the Class 204 schedule for the position of this Class in schedule hierarchy). This Class retains all pertinent definitions and class lines of .
The electroless nickel and immersion gold layers are deposited using a series of wet chemical baths. The wafers are first immersed in chemicals that clean the bond pads of any impurities and then in chemicals that activate the pad surface for selective deposition of the nickel. This activation is typically a "zincation" process fo r ...
Electroless nickel - immersion gold Electroless nickel – immersion gold (ENIG) is a flat, solderable, metallic finish on printed circuit boards and ceramic substrates. It serves to protect the copper from oxidation and ensures solde - rability and bondability with aluminium wire. In this process, the surfaces and vias intended for the finish ...

Electroless nickel plating is a process in which a nickel alloy is deposited on a metal surface via chemical reaction. Unlike nickel electroplating, electroless nickel plating does not require a power source to produce the deposit.
Various embodiments may provide an electrical connection structure. The electrical connection structure may include a first substrate having a first surface defining a cavity, and an inner wall defining a via extending from the cavity. The electrical connection structure may also include an interconnect structure provided in the via so that at least a portion of the interconnect structure ...
Electrodepositing a metallurgy such as gold on to printed circuit board features. The methods include electrolessly depositing a copper layer over the surface of the printed circuit board. This is followed by applying a layer of photoresist atop the electroless copper, and exposing and developing the photoresist to uncover areas to be etched, leaving behind the specific features to be plated.
