The quality of A-TECH hard gold pcb
can be guaranteed. It is manufactured according to the requirements and standards of the SANYO company. With a solder mask, it enjoys a good electrical insulation property2.
A-TECH CIRCUITS Co., Ltd.'s customer service team has the right skills for managing customers’ needs. It is 100% produced in accordance with IPC-6012 & IPC-A-600F standards3.
The product is notable for high energy efficiency. When it operates, it can utilize little energy as possible without any waste. It is extremely popular in the markets of Europe, North America, and Asia4.
The product has excellent stiffness and strength. It is able to withstand heavy load or force without deformation or malfunction. Being laminated by advanced vacuum lamination equipment, it has a uniform dielectric thickness after lamination5.
The product is less likely to happen electrical shock. Featuring an intelligent circuit design, it can prevent itself against the trip under the condition of overload voltage. It is vacuum-sealed, which can greatly reduce the bulk of the overall cargo
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.
As a well-established company, A-TECH CIRCUITS Co., Ltd. has been designing, manufacturing and distributing high-quality hard gold pcb for many years.2.
A-TECH now has mastered the high tech way of supplying higher quality hasl pcb
