What Is RAIG?
This is an immersion gold process for applying a thin layer of gold onto a substrate that you will find commonly used in the electronics industry.
In this process, we immerse the substrate in a gold-plating solution where a reducing agent facilitates the reduction of gold ions onto the surface of the substrate.
Unlike traditional immersion processes that rely on galvanic displacement, RAIG does not. Instead, it uses a reducing agent to improve the deposition rate and uniformity of the plating. This is an advantage because it helps achieve a more consistent and thicker gold layer.

Benefits and Applications
Reduction-assisted immersion gold provides enhanced uniformity, superior adhesion, improved conductivity, and corrosion resistance to the substrate and electronic component in general. Plus, it is an eco-friendly process. This is why it is particularly beneficial for:
- Printed Circuit Boards
- Semiconductor devices
- Connectors and Contacts
- Aerospace and defense electronics
These are just a few. There are many more applications of this immersion gold process.
What Reduction Assisted Immersion Gold Is Best For
RAIG is best for electronic parts that need a uniform gold finish, dependable conductivity, and strong corrosion resistance.
It is especially useful when a conventional immersion method may not deliver the consistency required across critical surfaces.
It is a practical option for:
- Printed circuit boards
- Semiconductor-related parts
- Connectors, contacts, and components used in demanding environments.
For manufacturers building high-performance electronics, the immersion gold process offers a dependable finishing option that supports product quality and long-term performance without making the finishing process more complicated.
Compatible Materials for Reduction-Assisted Immersion Gold
RAIG is commonly used on electronic substrates and parts that require a thin, consistent gold layer for performance and protection. In many applications, this includes PCBs, contact surfaces, and other precision components prepared for precious metal finishing.
Material compatibility depends on the part design, base metallurgy, surface condition, and the performance requirements of the finished component. Because these variables are important, Alternate Finishing, Inc. evaluates each job based on the specific part of the application.
That helps customers determine whether RAIG is the right fit for their parts and production goals.
What Affects Turnaround Time for Reduction Assisted Immersion Gold
Turnaround time for RAIG depends on several practical factors, including part quantity, part geometry, surface condition, inspection needs, and how the parts arrive for processing.
Job complexity is also important, especially when tight tolerances or applications-specific requirements must be met. In some cases, production scheduling and the need for fast quoting can also shape lead time.
At Alternate Finishing, Inc., specifically, we’re known for same-day quote responses and quick turn PCB finishing, with some jobs completed the same day when needed. That makes early communication about part specs, quantities, and deadlines helpful for keeping a project moving.
