China Customized Gold Fingers PCB Suppliers, …

Product Details: PCB gold fingers are narrow, rectangular PCB pads located along the edge of a PCB, typically hard-gold plated for electrical connections. They are used in applications such as memory sticks, graphics cards, and other devices requiring edge connections. The gold plating thickness ranges from 3u” to 50u” (microinches) or 0.05 μm to 5 μm (micrometers), depending on the application. The process involves electroplating gold over a nickel layer to enhance conductivity, corrosion resistance, and mechanical strength[1][2][4].

Pros:
– Provides excellent conductivity and low contact resistance
– Resists corrosion and oxidation over long-term use
– Allows many insertions and removals without degradation
– Provides lubricity for smooth insertion into mating connectors
– Protects against fretting wear during vibration or shock
– Ensures solderability for terminations and connections

Cons:
– Higher manufacturing cost, especially for electroplated hard gold
– Requires careful design to avoid defects such as pad lift, solder fractures, or…
– Needs specific spacing and alignment rules to ensure reliability
– May be prone to abrasion if not properly designed or if using softer gold platin…

China Gold Finger Plating PCB Manufacturer

Product Details: PCB gold fingers are gold-plated leads located at the edge of a PCB, designed for easy peripheral connectivity. They are used in applications such as PCI, ISA, or AGP slots to connect peripheral devices to the motherboard. Key specifications include a minimum distance of 0.5mm between the gold fingers and the PCB outline, avoidance of soldermask or silkscreen printing near the gold fingers, and a maximum length of 40mm for the gold fingers. The gold plating thickness ranges from 2 to 50 microinches, with standard thicknesses of 0.031, 0.062, 0.093, and 0.125 inches. The plating process typically involves nickel and

hard gold with cobalt for enhanced rigidity and conductivity.

Frequently Asked Questions (FAQs)

Frequently Asked Questions About Gold Finger Factories in China

What is a gold finger PCB and what are its key characteristics?

A gold finger PCB is a type of printed circuit board with gold-plated connectors, typically found at the board edges. These connectors facilitate critical connections and power distribution within electronic devices. They are known for their good electrical conductivity, wear resistance, and oxidation resistance. The gold layer, often referred to as “hard gold,” is usually between 0.25-1.3 microns thick, depending on the application.

How are gold finger PCBs manufactured?

The manufacturing process of gold finger PCBs involves several steps, including drilling, plating, imaging, and etching. A layer of dielectric nickel is first plated on the copper surface, followed by the gold plating. The edges of the gold fingers are beveled to ensure smooth insertion into corresponding slots. Additionally, a solder mask window is created to expose the gold finger’s pad while keeping the surrounding area covered.

What are the design considerations for gold finger PCBs?

When designing gold finger PCBs, it’s crucial to maintain a minimum distance between the gold finger and other components to prevent interference. The gold finger’s surface should not be covered with copper, and inner layer copper should be cut to avoid performance issues. The spacing between gold fingers and other components, such as through-holes and solder masks, must also be carefully managed.

How do you choose a reliable gold finger PCB manufacturer in China?

To choose a reliable manufacturer, you should conduct thorough research online, participate in industry trade fairs, and verify supplier credentials. Look for manufacturers with ISO certifications (e.g., ISO 9001, IATF16949) and a strong reputation. It’s also important to check if the manufacturer performs all processes in-house to ensure quality control and offers customization options to meet your specific needs.

What are the cost considerations and cost-saving methods for gold finger PCBs?

The cost of gold finger PCBs can vary based on the thickness of the gold layer and the manufacturing process. To save costs, you can use a combination of HAL (Hot Air Leveling) technology and gold plating, where the rest of the PCB surface uses HAL and only the gold finger area is plated with gold. This method can lower production costs without compromising the functionality of the PCB.
