Gold Fingers
Gold fingers, also known as edge connectors, are a crucial component in modern electronics, providing a reliable interface between PCBs and external devices. At ELIPCB, we understand the importance of precision and quality when it comes to gold finger plating.
What are Gold Fingers?
Gold fingers are the exposed, gold-plated contact points located at the edge of a printed circuit board (PCB). They are designed to establish a secure electrical connection between the PCB and external components or devices. Due to their exceptional conductivity and resistance to corrosion, gold fingers are widely used in applications where reliable connections are paramount.
Benefits of Gold Fingers:
Exceptional Conductivity: Gold is an excellent conductor of electricity, ensuring low resistance and reliable signal transmission.
Corrosion Resistance: Unlike other metals, gold does not corrode or oxidize, providing long-term reliability and durability.
Solderability: Gold fingers are easily soldered, making them compatible with various assembly processes.
Longevity: Gold plating offers extended lifecycle compared to other materials, reducing the need for frequent replacements.
Signal Integrity: The smooth surface of gold fingers minimizes signal loss and interference, crucial for high-frequency applications.
Types of Gold Finger Plating:
Hard Gold (Electroplated Gold)
This type of plating is ideal for applications where durability and wear resistance are essential. Hard gold plating offers a thick layer of gold for enhanced longevity.
Soft Gold (Immersion Gold)
Immersion gold plating provides a thinner layer of gold but excels in achieving flat and even surfaces. It's widely used for fine-pitch components and high-frequency applications.
