Key steps in the process include:

1. Cleaning: The PCB is thoroughly cleaned to remove any contaminants.

2. Micro-etching: A mild acid treatment roughens the copper surface for better adhesion.

3. Activation: The surface is activated with a palladium catalyst.

4. Nickel plating: A thin layer of nickel is deposited as a barrier between copper and gold.

5. Immersion gold plating: The board is immersed in a gold solution, where gold ions replace the surface nickel atoms.

This process offers several benefits for CCTV camera PCBs:

• Enhanced corrosion resistance, crucial for outdoor cameras

The plating process typically begins with cleaning and preparing the PCB surface. Next, an electroless nickel plating method is employed, which doesn’t require an external power source. This results in a uniform nickel layer across the board, including within plated through-holes. The nickel coating provides excellent corrosion resistance, extends the shelf life of the PCB, and enhances its ability to withstand multiple soldering cycles.

Two-layer PCB nickel plating is particularly beneficial for applications requiring high reliability, such as automotive electronics, aerospace systems, and industrial equipment. It also improves the board’s resistance to wear and tear, making it ideal for devices subject to frequent handling or harsh environments.
