How Does Flash Gold Plating for PCBs Work?

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 electrically? As not all pads and traces are connected together, how will this be achieved? Any help is welcome! Thanks! Horst Space

PCB and connector commonly used gold plating process

2020-6-4  PCB common gold plating process Nickel plating Gold Flash The term "Flash Gold" is derived from the English Flash, which means fast gold plating, commonly known as water gold plating. In fact, it is a "pre-gold plating" procedure for electroplating hard gold. It uses a larger current and a thinner gold-containing liquid bath.

The difference between ENIG and flash gold in PCB design

2020-12-24  ENIG PCB and flash gold PCB are commonly used in PCB design and PCB production. With the increasing integration of IC, IC pins are more and more dense. However, it is difficult for HASL process to blow even the fine pad, which brings difficulty to SMT assembly; in addition, HASL PCB has a short service life. Flash gold PCB solves these problems.

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.

Difference between ENIG and Flash?

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 galvanic-driven pore corrosion.

ENIG vs Flash Gold SMTnet

2006-3-27  ENIG vs Flash Gold 24 March, 2006. Flash gold is just thin gold plating over electroless nickel or electrolytic nickel. 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.

Understanding the Risk of Gold Flash PCB Design

2021-10-22  Flash is also poorly controlled compared to immersion process, which result in an excess of gold in certain areas of the board, increasing the risk of gold embrittlement. Conclusion Except for toys and other very limited‐life (<6 months) products produced in very high volumes, flash gold should be avoided unless it is plated over another
