high quality hasl pcb free bulk production for wholesale

Product Comparison

PCB prototype has the following advantages over other products in the same category.

Company Advantages
1. Materials used for hasl pcb is periodically renovate to make it own best properties.
2. The product has enough hardness. It can effectively resist scratching due to the friction or pressure from a sharp object.
3. The product is lightweight. It is made of extremely lightweight fabric and lightweight accessories such as zippers, and inner lining.
4. A-TECH is well-appreciated by customers for its not only the hasl pcb but also the service.

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.
