Company Advantages
1. Gorgeous design of lead free hasl pcb shows A-TECH CIRCUITS Co., Ltd.'s advanced technologies. Being laminated by advanced vacuum lamination equipment, it has a uniform dielectric thickness after lamination
2. The product can be versatile thanks to its low energy consumption. It can effectively save energy and reduce electricity bills.
3. This product has high light color accuracy. It is able to make the thing being illuminated look the same as its original color. The product can be resistant to corrosion
4. This product is ecologically sound. Amongst available cladding material, whenever possible, non-solvent paints, PET thermic isolation, and re-cycled panels are preferred for it. Its robust structure allows it to be used in harsh environments
5. It is not prone to burn out due to excessive temperatures. It is designed with a temperature protection system to prevents internal components. Its solder mask can be offered with green, blue, white, black, yellow, and red colors


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.
