  • How Does Flash Gold Plating for PCBs Work? Finishing

    I would like to get a better understanding how electrolytic plating works. Flash gold, being an electrolytic process, an electric current is required to plate the gold onto the board. How will this be implemented in the industry? Will all the pads and traces of the PCB have to be connected

  • Difference between ENIG and Flash? Circuitnet

    Flash describes the plating thickness. Flash typically means a very thin (3 to 10 microinches) coating of gold, regardless of the process. Therefore, flash gold could be electrolytic, electroless, or immersion. Initial problems with flash gold in the 1990's tend to refer to an electroless process used over separable connectors that resulted in

  • Printed Circuit Board PCB Assembly Bay Area Circuits

    In rare instances, when a printed circuit board requires “body gold,” the finish is applied to the copper prior to the soldermask process. Gold finishes tend to be more expensive. However, when it comes time for printed circuit board assembly, the consistent finish may be worth the extra cost, especially for designs that require a very

  • PWB Processes: ENIG nickel free PCB coating

    PWB Processes: ENIG KAT Electroless Nickel/ Immersion Gold (ENIG) KAT ENIG is the industry standard for producing uniform mid phos EN deposits with a thin topcoat of immersion gold, over copper substrates. This PCB finish is highly resistant to corrosion, and is both solderable and aluminum wire bondable. It is an ideal contacting surface.
