hot-sale pcb mask leveling bulk production at discount

Company Advantages
1. A-TECH silver coating pcb has to go through various kinds of tests, including a safety test for both patients and operators, chemical resistance test and biocompatibility test. Its robust structure allows it to be used in harsh environments
2. A-TECH CIRCUITS Co., Ltd. has an infrastructure that gives it a massive competitive advantage over other companies in pcb mask field. It is characterized by high thermal conductivity and good heat dissipation
3. Good reliability is one of the biggest selling points of the product. The reliability guarantees consistent performance throughout the lifetime of the product.
4. The product is not prone to blast. It will not have spontaneous combustion or burning even it's squeezed, dropped, and shocked. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density
5. It is heavily resistant to all forms of weather. Advances in manufacturing techniques have increased the choice of materials, with required properties such as weather resistance and corrosion resistance. The product can be resistant to corrosion

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.
