Rich ENIG PCB manufacturing
HTD Group has a long history with ENIG employed in prototype to mass production.

ENIG PCB processes for customers
Driven by the needs and demands of PCB industry and OEMs, HTD Group circuits developed several ENIG processes, which are already established in the market.

HTD ENIG PCB processes capability
HTD Group circuit's ENIG processes provide maximum thickness uniformity and perfect planarity for aluminium wire bonding and when Ni/Pd/Au plated for gold wire bonding.

HTD circuit processes advange
In case a PCB manufacturer has to stop and resume production frequently, the dummy-plating-free AuNic process will help to save time and money.

ENIG PCB types
ENIG is a two layer metallic coating of 2-8 μin Au over 120-240 μin Ni.

Nickel of ENIG PCB definiton
The Nickel is the barrier to the copper and is the surface to which the components are actually soldered to.

Gold ENIG PCB definition
The gold protects the nickel during storage and also provides the low contact resistance required for the thin gold deposits.

ENIG PCB boards type
ENIG is now arguably the most used finish in the PCB industry due the growth and implementation of the RoHs regulation.

Resists HASL PCBs with ENIG PCBs
We make electronic equipment used in corrosive environments.
Experts suggest we use hot air solder leveling (HASL) as a finish on circuit boards instead of immersion gold.

Supposedly, this resists corrosion better.
Do you recommend use of HASL vs. immersion gold for our application?
Would you recommend another type of finish?
