Product Comparison
Compared with products in the same category, Aluminum PCB has the following advantages.
Application Scope
A-TECH's Aluminum PCB can be used in multiple industries and fields.A-TECH is committed to providing customers with high-quality PCB prototype as well as one-stop, comprehensive and efficient solutions.
Company Advantages
1. There are two ways to quickly build A-TECH osp pcb finish . One is by stacking them together and cutting the openings, welding the sides and constructing the electrical and pipe networks, and the other is to cut and create all the necessary networks before you begin the stacking and positioning process.
2. The product can support both the off-grid and on-grid system. It collects and stores the sunlight during the day, and makes the power available.
3. Our perfect packaging will be conducive to the safety of pcb surface finish .


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.
