During the design phase of A-TECH tin plating pcb
, we keep close eyes on customers' needs. It totally conforms to the UL Flame Rating of 94V-02.
Following through on the promises applies to A-TECH CIRCUITS Co., Ltd.'s every step of the customer-service process. It is offered with low dielectric loss3.
It is highly accurate when it operates. With a precise control system, it can work flawlessly and consistently under the given instructions. It is 100% produced in accordance with IPC-6012 & IPC-A-600F standards4.
The surface of the product is smooth and flat. Singeing technique is a kind of technique which enables yarns or fabrics to pass through a flame or rub on a hot metal surface to remove surface hair It is extremely popular in the markets of Europe, North America, and Asia5.
The product is characterized by increased uptime. It has an integrated control system to reduce disgusting downtime and long automatic restarts. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density
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
●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.
