In this blog post, We will discuss the challenges we faced during the design and manufacturing process and how we overcame them.

1. Achieving 1mm Thickness:
Designing slim and lightweight metal case earbuds while maintaining strength and durability was a complex task. We conducted extensive research and development to identify a specialized aluminum alloy that offers exceptional strength and durability, allowing us to achieve a thickness of 1mm without compromising performance.

2. Creating Anodized Colors:
Providing vibrant and long-lasting anodized colors for the earbud casing was a challenge. Through collaboration with our suppliers, we developed a unique anodization technique that ensures a wide variety of colors while maintaining durability and visual appeal.

3. Ensuring Precise Assembly:
The assembly process demanded meticulous attention to detail. Our assembly team underwent rigorous training and implemented advanced quality control measures to ensure precise alignment and secure connections of components, guaranteeing optimal performance and longevity.

By overcoming these challenges, our metal case earbuds have gained recognition in the market. Users appreciate the sleek design, vibrant colors, and exceptional audio experience they provide. We will continue to innovate and refine our earbuds to deliver cutting-edge technology, superior comfort, and an immersive audio experience.

Thank you for your interest and support in our metal case earbuds. If you have any questions or would like to learn more, please reach out to our customer service team. We are excited to embark on this journey of music and innovation with you

Beryllium copper finger contacts are commonly used in electronic connectors due to their excellent conductivity, durability, and resistance to corrosion. However, to enhance their performance and longevity, it's often necessary to apply a layer of gold plating on the contact surface. Here are some benefits and considerations of gold plating beryllium copper finger contacts.

1. Improved conductivity: Gold is highly conductive, with a low resistance to electrical current. By plating beryllium copper finger contacts with gold, you can increase their conductivity and reduce the risk of signal loss or interference.

2. Corrosion resistance: Gold is highly resistant to corrosion, oxidation, and tarnishing, making it an ideal coating for electronic contacts that are exposed to harsh environments or frequent use. Gold plating can protect beryllium copper finger contacts from corrosion and extend their lifespan.

3. Low contact resistance: Gold plating creates a smooth and uniform surface on beryllium copper finger contacts, reducing the contact resistance between the mating surfaces. This can improve the reliability and performance of electronic connectors, especially in high-frequency or high-speed applications.

Considerations for Gold Plating Beryllium Copper Finger Contacts

When considering gold plating for beryllium copper finger contacts, there are several factors to keep in mind:

1. Thickness and purity: The thickness and purity of the gold plating can affect its performance and cost. Thicker plating can provide better conductivity and durability, but it may also increase the risk of cracking or peeling. Higher purity gold can offer better corrosion resistance and contact reliability, but it may also be more expensive.

2. Adhesion and compatibility: Gold plating should adhere well to the beryllium copper substrate and not cause any adverse reactions or galvanic corrosion. It's important to choose a plating process and solution that are compatible with the beryllium copper material and the intended application.

3. Cost and lead time: Gold plating can add to the cost and lead time of electronic connectors, especially for high-volume or custom orders. It's important to balance the benefits of gold plating with the overall cost and performance requirements of the project.
Our factory can offer customized real gold plating finger contact in different thickness gold layer and offer the test report.Usually the finger contacts will be packed with SMT reel.
