How Does Flash Gold Plating for PCBs Work?

The PC board is fabricated with a shorting bar that connects all plug-in tabs. Then after plating the shorting bar is cut off. Another way is to mask the board (or control depth) and plate the fingers before the board is etched. Be sure to put nickel under the gold to help stop the copper from migrating right thru the gold.

PCB Prototype

ENIG (Electroless Nickel Immersion Gold) or Immersion Gold or Cheminical Gold has widely replaced ‘Flash Gold’ (electro), which was so widely used in the 1990s in Asia. ENIG has become ‘the’ surface finish of reference for multi-layers PCB and fine pitch boards. Note: the components are soldered on the nickel; gold is only present to protect the former one.

31/03/2021  This process involves coating thin gold over thin layers of nickel. The thin nickel layers are widely used since they perfectly serve as a protector for the PCB plating and the component's soldered areas. Thus, it safely secures the stored nickel. However, this process of electroless nickel immersion gold is very costly.

Surface Finishes: Why do I need to know more?

A.K.A: Flash Gold, Electrolytic Gold, Full body Hard Gold, Tab Gold, Selective Gold *IMPORTANT - Electrolytic process, all copper surfaces to be plated must be electrically connected to a rectifier (power supply), unless “gold as etch resist” process is used. Unplated copper must be covered by mask or resist. Gold has grain stiffeners and brighteners added.

ENIG vs Flash Gold - SMTnet

27/03/2006  Flash gold is electrolytic gold where the panel is connected to a plating rectifier and current causes the plating process to occur. Gold thickness is controlled by time in the bath and current density. Flash gold will become thick gold if time in the bath goes too long. Immersion gold is gold plating over electroless nickel.

Difference between ENIG and Flash?

Difference between ENIG and Flash? With PCB plating what's the difference between ENIG and Flash? Mike Johnson: Expert Panel Responses: You are comparing apples to oranges. ENIG describes materials (nickel and gold) and processes (electroless for nickel and immersion for gold). 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
