What is ENIG PCB board?

ENIG (Electroless Nickel/lmmersionGold) is a surface finishing process for PCB (Printed Circuit Board). This process plates a layer of nickel-phosphorus alloy on the surface of copper first through a chemical reaction, and then plates a layer of gold on the surface of nickel through a replacement reaction, forming two layers of metal coating.
This surface finishing process can effectively prevent the oxidation and corrosion of copper, improve the solderability and reliability of the PCB.

Advantages

Wide range of applications: The ENIG process is suitable for a variety of PCB application scenarios, including lead-free soldering, SMT (surface mount technology), BGA (ball grid array) packaging, etc.
Improve reliability: Through the formation of dense nickel-phosphorus alloy layer and gold layer, can effectively improve the reliability and durability of PCB.
Environmental protection: ENIG process is a lead-free surface treatment process in line with environmental requirements.

Application

The ENIG is used in a wide range of applications such as data/telecom, high-end consumer products, aerospace, military, high-performance equipment and medical industries. The ENIG process meets the high requirements for reliability, durability, and environmental friendliness of PCBs and provides a superior solution for these applications.
