What Is PCB Immersion Gold ENIG Surface Finish?
Product Details: ENIG (Electroless Nickel Immersion Gold) is a surface finish used in PCB manufacturing. It involves depositing a Ni-P alloy on a catalyzed Pd surface, followed by a thin layer of gold through a displacement reaction. This process protects the copper surface from oxidation and enhances solderability. The nickel layer acts as a barrier to the PCB base material, while the gold layer protects the nickel and provides low-contact resistance. The process includes cleaning, micro etching, activation, nickel plating, and immersion gold stages[2][3][5].

The Difference Between Gold Plating and Immersion Gold
China Immersion Gold Manufacturer and Supplier, Factory
Product Details: Immersion gold is a process used for PCB surface finish, involving the deposition of a gold layer on the PCB conductors by immersing the boards in an aqueous gold solution containing ions of a reducing agent. The process is auto-catalytic and does not require external electrical current. It is suitable for double-sided and multilayer boards, high-density interconnect (HDI) boards, and fine features below 100 microns. The thickness of the gold layer typically ranges from 3 to 8 micro-inches and is controlled by immersion time, solution parameters, and temperature.
Pros:
– Simple process with no electrical instrumentation
– Lower equipment and processing costs
– Uniform coverage on all surfaces
– Faster processing time
– Suitable for fine features and PCBs with dense spa…
Cons:
– Lesser control on thickness uniformity and reprodu…
– No possibility of selective plating
– Lower purity, hardness, and bondability
– Less wear resistance and durability

Frequently Asked Questions (FAQs)
What is the Immersion Gold (ENIG) process in PCB manufacturing?
The Immersion Gold, or ENIG, process is a method used to deposit a nickel-gold coating on the surface of printed circuit boards (PCBs). It involves several stages?
pre-treatment to clean and activate the copper surface, electroless nickel plating, immersion gold plating, and post-treatment. This process ensures a stable, bright, smooth, and solderable surface, protecting the copper from oxidation and enhancing the PCB’s performance and durability[1][3][5].
