How the ENIG Immersion Gold Line Ensures Reliable PCB Surface Finish

The ENIG (Electroless Nickel Immersion Gold) process is one of the most trusted surface finishes in PCB manufacturing. This video shows how each PCB passes through cleaning, nickel deposition, and gold immersion to create a durable, solderable surface. Stable chemical control and precise plating thickness help ensure excellent reliability during assembly and long-term use.
