Conductive Silver Paste for High Frequency Filter

Conductive silver paste for high-frequency filter is specifically designed to provide excellent electrical conductivity and stability in high-frequency applications. It typically consists of silver particles suspended in a silicone polymer, which allows for easy application and adhesion to various substrates. When applied, the conductive silver paste forms a robust and reliable conductive path that minimizes signal loss and interference, making it ideal for use in RF (radio frequency) and microwave filter designs. Additionally, its thermal and mechanical properties contribute to the overall performance and durability of high-frequency filters, ensuring that they meet the stringent requirements of modern telecommunications and electronic devices. Furthermore, its compatibility with different substrates and ease of application further enhance its utility in the electronics industry.

Technical Parameters

Performance

• Uniform sintered film layer. The conductive silver paste for high-frequency filter produces a consistently uniform film layer after the sintering process, ensuring optimal performance and enhanced reliability in high-frequency applications.
• Smooth surface finish. Following the dip coating and centrifugation processes, the surface of the film exhibits a smooth and refined finish, which contributes to improved aesthetic quality and functional performance.
• Excellent conductivity with low insertion loss. The conductive properties of the silver paste are exceptional, resulting in low insertion loss. This ensures efficient signal transmission and enhances the overall effectiveness of high-frequency filters.
• Superior solderability and solder resistance. The product demonstrates outstanding solderability, allowing for seamless integration in various applications. Additionally, it possesses excellent solder resistance, ensuring durability and longevity under thermal and mechanical stress.

Precautions

• The ambient temperature is recommended to be maintained between 20°C and 25°C, along with humidity levels between 50% and 60% during the application process to ensure optimal performance.
• The recommended thickness for the coating should be between 10 and 15 μm for effective application.
• The silver paste should be used within 24 hours after it has been opened. It is crucial to seal the unused portion properly by securing both inner and outer covers to prevent exposure to air, which can compromise its quality.
• If you need to recycle the silver paste, ensure to use a specialized thinner for viscosity adjustment. This will help maintain the desired consistency for effective application.
• When removing silver paste from refrigeration, allow it to acclimate to the operating temperature (ideally 20°C to 25°C) for at least 4 hours. It is important to keep the packaging sealed during this acclimatization period to avoid contamination or moisture absorption. After achieving temperature equilibrium, open the lid and stir the paste thoroughly for uniformity.
• Ensure that the working environment is free from corrosive gases, such as sulfides and chlorides, as these can adversely affect the performance and longevity of the silver paste.
• In the event of skin contact with the silver paste, promptly wash the affected area with soap and water to ensure safety and prevent irritation.
