Dissimilar material bonding using AuSn solder for optical devices
Strongly bonding dissimilar materials such as glass-metal and ceramics-metal.
In the optical equipment industry, lenses are crucial components that significantly influence performance. The manufacturing of lenses requires the combination of different materials, and the bonding technology greatly affects the quality and reliability of the products. Particularly in environments exposed to temperature changes and vibrations, the durability of the bonded joints becomes essential. Our AuSn solder bonding technology firmly joins dissimilar materials such as glass, metal, and ceramics, ensuring the long-term reliability of optical lenses. 【Application Scenarios】 - Bonding lenses to metal frames - Bonding lenses to ceramic components - Sealing various optical components 【Benefits of Implementation】 - High chemical resistance and water resistance - Stable performance in high vacuum environments - Improved long-term reliability

The area where Citizen Fine Devices demonstrates its strength is in the realm of functional components that require small size, precision, high accuracy, and high detail. We believe that our mission is to continue providing high-value-added microdevice products by leveraging the unique technologies we have developed over many years. Utilizing metal processing technology rooted in watch manufacturing, we have consistently supplied small, high-precision components to our customers for many years through a fully integrated production line that encompasses process design, machining, assembly, and functional testing, along with the unique development of our own processing machines. Additionally, mass-producing components with high precision and efficiency using brittle materials is also one of our core technologies. By integrating material technology with ultra-precision machining, thin-film technology, and bonding technology, we produce not only high-precision components such as ceramics and quartz but also high-quality functional device products like liquid crystal devices and sensing devices. Continuing to provide high-value-added products to the market is a significant dream for our employees. We will contribute to the creation of new value through manufacturing driven by the challenge spirit of each individual, working towards the realization of that dream.
