Company Advantages
1. A-TECH has gone through the following production process: the preparation of shell pattern, stitching, lasting (to shape the final shoe.), and final assembly. Its solder mask can be offered with green, blue, white, black, yellow, and red colors
2. For every room of the house, this product is the most common choice for people to store goods, food, and beverages. It has high tensile strength and can be deformed without breakage
3. The product causes no injury. Its edges and corners are all rounded and polished to eliminate sharp and irritating burrs. It is offered with low dielectric loss
4. This product features wear comfort. In the design stage, improvements in thermal and tactile comfort are explored and achieved based on the development of textile surfaces. The inner layer core of the product is chemically treated for improved adhesion of the copper surface
5. This product has required safety. It has no sharp points, edges, or potential areas for unintended squeezing/entrapment of fingers and other human appendages. It totally conforms to the UL Flame Rating of 94V-0


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.
