Company Advantages
1. Such pattern design of immersion tin pcb is exquisite and special. Its solder mask can be offered with green, blue, white, black, yellow, and red colors
2. The product is popular in the market currently and can be more widely used in the future. A smooth part is added on its PTH line to reduce the roughness of through hole
3. As LED lights are extensively used in many fields, it is produced with a variety of specifications and applications for different market demands. It has high tensile strength and can be deformed without breakage
4. The product features strong resistance to shock. Its shock-proof capacity protects the LED chips or other components from detachment during transportation and shipping. Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance
5. Strict quality standards are established in the inspection process to ensure the high quality of products. It has low water absorptivity in the damp environment


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.

A-TECH immersion tin pcb is produced under strict scrutinization. It is checked for its material ingredients as well as material extraction methods to guarantee its quality. Screen printing and embossing can be applied to the product
The production of A-TECH hard gold pcb covers a few steps. The rough concentrate is deeply processed at first to extract some useful ingredients, then the concentrate is further ground for higher purity. It is made of stainless steel, which showcases premium rust-resistance
High-tech processing equipment is used in the production of A-TECH enig pcb. It is done under the detritus equipment, grinding equipment, as well as sand-making equipment, which can guarantee high purity and fineness. It helps keep constant temperature which will not ruin beer flavour
The raw materials of A-TECH immersion tin pcb are treated with several procedures. Materials enrichment, refining, and smelt process will be conducted to make the materials into a product with high purity. Its shell is water-proof and dust-proof, making it suitable for beverage storing
A-TECH immersion tin pcb will go through several manufacturing stages. First, the raw materials will be crushed and ground, then they are separated and concentrated to separate the waste ingredients out. 卖点、特色句]
