How to Produce Gold Fingers PCB?

Gold Finger PCBs have inversely a very positive element in their feature list: durability, the edge connectors inside our fingers have gold plating, which means superiority in conductivity, as well, what adult home toy device would be complete without rugged gold finger PCBs to make sure that connections are sewn together tightly and without any interruption? These PCBs come with gold plated edge connectors for plugging into slots i.e., used as edge connectors or used to plug into slots PCB. As a premier gold finger PCB manufacturer, and professional solution provider, we are committed to provide the most innovative and cost-effective design and production services for the telecom, aerospace, medical device, consumer electronics, and other industries.

What Is a PCB with Gold Fingers?

Gold fingers are the gold-plated contacts that connect a printed circuit board with other boards or devices and are usually part of the edge of the PCB. Gold plating provides great conductivity, corrosion resistance, and wear resistance. These PCBs are commonly seen in applications where repeated insertion and removal times may be required like graphics cards, motherboards, and similar high-end electronic gadgets. Gold fingers PCBs are built to perform into the highest levels of industry standards, making sure your performance is as high as you want it to be. As one of the leading gold finger PCB manufacturers, we know the necessity of accuracy and consistency in every process of production. 

Important Process of Manufacturing Gold Finger PCBs

The manufacture of gold fingers PCBs needs to advanced technology and rigorous quality assurance. Following are the principle is steps involved:

Design and Layout of the PCB
The process starts with the PCB layout design, arranged the gold fingers well for connectivity. The design must follow the industry such as IPC standard and contain the space, measure and alignment of the gold finger.

Surface Preparation
The PCB surface is prepared prior to the application of the gold plating to maintain a clean and flat surface. This involves eliminating any oxidation, dirt or residue that would have an impact on the plating.

Nickel and Gold Plating
Gold fingers are silver plated, then nickel plated and capped with a final thin coat of gold. The gold layer on top provides good conductivity as well as abrasion protection, but the nickel layer serves as a better barrier layer against moisture and metals diffusion (including gold) into the copper substrate. And as a leading gold finger PCB manufacturer, we apply state-of-the-art plating technologies to achieve a consistent, high-quality finish.

Beveling
The edges of the gold fingers are also beveled at specific angles to facilitate smooth entry into connectors, which matches the 30 or 45 degree standard one. This process requires extremely high accuracy without breaking the connectors or the PCB itself.

Surface Finishing
After plating and beveling, the PCB is subject to surface finishing to improve its wear resistance and offer certain protection to the environment. Popular finishes are ENIG (Electroless Nickel Immersion Gold) and hard gold plating, these 2 finishes can be used in gold finger PCB also and have superior performance.

Testing and Quality Control
Each and every gold finger PCB undergoes testing to meet the required specification. This process involves electrical testing, measuring the gold plating thickness and visual inspection for identifying any defects.
