ENIG surface finish PCBs with flat pads, RoHS compliance, and long shelf life. Ideal for BGA, fine pitch SMT, and high-reliability use.
ENIG PCB – Enhanced Durability and Solderability
Electroless Nickel Immersion Gold (ENIG) is a premium PCB surface finish, offering flat solder pads, corrosion resistance, and excellent wire bond reliability. At China 365PCB, we apply ENIG with precise thickness control as part of our PCB manufacturing process—ensuring consistent nickel (3–6µm) and gold (0.05–0.1µm) layers that deliver optimal solderability and long-term reliability for demanding applications.

“ENIG boards from China 365PCB deliver superior solder joints. Works great with BGAs.” – Thomas Y., SMT Supervisor, CleanConnect Inc.
Q1: Why choose ENIG over HASL?
A: ENIG provides better flatness and longer shelf life for SMT.
Q2: Is ENIG lead-free?
A: Yes, it’s fully RoHS-compliant.
Q3: Can ENIG be used with wire bonding?
A: Yes, it's compatible with both Au and Al wire bonding.
Q4: Is ENIG suitable for HDI designs?
A: Absolutely. ENIG is ideal for fine pitch and via-in-pad designs.
Q5: What’s the shelf life of ENIG boards?
A: Typically 12+ months under proper storage.
