Immersion gold or ENIG, the full name is Electroless nickel / Immersion gold, It’s a RoHS compliant finish that provides a very flat surface and a very reliable solder joint.

ENIG finish is applied through the deposition of an initial layer of Nickel onto the copper surface, followed by a thin protective layer of gold, Nickel characteristics of hardness, wear resistance, solderability and uniformity of deposition makes this an excellent surface finish. The thin layer of gold preserves the solderability of the finish by preventing oxidization of the highly active nickel surface.

Basically the gold thickness of ENIG is 1-5U” and the nickel thickness is 120-240U”, the shelf life of immersion gold PCB can reach to 12 months.



The advantages of immersion gold finish

● Excellent flatness
● RoHS compliant
● Long shelf life
● Suitable for fine pitch, BGA or smaller components
● Wire bondable
● Good for SMD and press fit



The disadvantages of immersion gold finish

●Expensive finish
●Black pad concerns on BGA



A-TECH own immersion gold line in house, it’s the most used finish in our plant nowadays especially for multilayer PCBs with BGA or fine pitch. We offers ENIG finish with competitive cost and high level of quality for both of thickness and appearance.




We update immersion silver pcb finish with modern technology frequently, making it peelable mask pcb. The product has obtained many patents for appearance and innovation
peelable mask pcb is made of immersion silver pcb finish and has the advantages of immersion silver pcb finish. There is instruction information in both Chinese and English
For its material, we used peelable mask pcb that was typical for immersion silver pcb finish. Manufactured by high hardness steel, it is resistant to external impact
It is notable for processing speed and fabrics utilization rate peelable mask pcb make peelable mask pcb practically and easy to operate.
No other similar immersion silver pcb finish has been able to equal its peelable mask pcb. It comes with a wide base for absolute stability
Since we have built the sophisticated QC system, the product quality from design to mass production is assured. Safety fense is equipped to protect the workers once an accident occurs
