A-TECH hot-sale peelable mask pcb bulk production at discount

Company Advantages
1. There are many factors influence the design of A-TECH tin plating pcb . They are size, weight, required motion, labor required, speed of operation, etc.
2. This product naturally resists fire. Make of fire retardant natural fiber, it is difficult to ignite and may extinguish smaller flames on its own.
3. The product has a precise dimension and other parameters. Machined by CNC machine, it is cut and processed under the precise numerical control of every detail.
4. Laying stress on the customer service is a good point for the development of A-TECH.
5. A-TECH CIRCUITS Co., Ltd. takes responsibility for its actions and contributes to society.

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.
