EMI specific copper powder has excellent conductivity and thermal conductivity, which can effectively shield electromagnetic wave interference and ensure the normal operation of electronic devices

Time:2023-05-13Number:1100

EMI (Electromagnetic Interference) copper powder is a high-performance conductive material widely used in fields such as suppressing electromagnetic interference and RFI (Radio Frequency Interference).
EMI specific copper powder is also commonly usedElectromagnetic interference shieldingThe materials. It has excellent conductivity and thermal conductivity, which can effectively shield the interference of electromagnetic waves and ensure the normal operation of electronic devices. This material is widely used in fields such as electronics industry, communication equipment, aerospace, etc.
The following is an introduction to EMI specific copper powder:

  1. Preparation process:EMI specific copper powderChemical reduction method, gas phase condensation method, plasma spray method and other preparation methods are usually used. These methods can prepare EMI specific copper powder with narrow particle size distribution, regular morphology, good conductivity, and strong corrosion resistance.

  2. Special function: Due to the excellent conductivity of EMI specific copper powder, it can effectively resist electromagnetic interference and RFI noise, and protect electronic devices from the impact of these noises. In addition, EMI specific copper powder can also improve the anti-static and anti-corrosion performance of electronic devices.

  3. Application areas: EMI specific copper powder is widely used in various electronic devices, including televisions, mobile phones, tablets, wireless network devices, medical equipment, etc. In addition, it can also be used in electronic devices in fields such as automotive, aerospace, and defense to enhance their noise and corrosion resistance.

  4. Environmental friendliness: EMI specific copper powder is usually prepared using pollution-free processes such as chemical reduction, which greatly reduces environmental pollution compared to traditional electrolysis methods. In addition, EMI specific copper powder itself has good corrosion resistance and stability, which prevents secondary pollution during use.

  5. Economic benefits: EMI specific copper powder can improve the anti-interference and anti-corrosion performance of electronic devices, thereby extending their service life and reducing maintenance and replacement costs. Therefore, the widespread use of EMI specific copper powder in electronic device manufacturing can bring good economic benefits.

In the production and application process of EMI (Electromagnetic Interference) specialized copper powder, some technical difficulties are often encountered. Here are some common technical challenges and their solutions:

  1. Problem: Particle size is too large or uneven. Excessive or uneven particle size can affect the conductivity and dispersibility of EMI specific copper powder.

    Solution: This problem can be solved by changing the preparation process parameters, adopting more advanced preparation methods, and introducing grading and sorting methods.

  2. Problem: The thickness of the oxide layer is too large. The oxide layer generated on the surface of EMI specific copper powder will affect its conductivity and corrosion resistance, so it is necessary to control the thickness of the oxide layer.

    Solution: Reducing agents can be used to remove the surface oxide layer, or surface active agents can be added during the preparation process to control the thickness of the oxide layer.

  3. Problem: Poor fluidity at low temperatures. EMI specific copper powder is prone to poor flowability in low-temperature environments, which affects its processing performance during use. Solution: This problem can be solved by adding fluidity enhancers, increasing production temperature, and other methods.

  4. Problem: Particle aggregation. During storage and use, EMI specific copper powder is prone to particle aggregation, which affects its dispersibility and conductivity.

    Solution: This problem can be solved by methods such as ultrasonic oscillation and adding dispersants.

  5. Problem: Poor corrosion resistance. EMI specific copper powder is susceptible to oxidation and other environmental factors, leading to a decrease in its corrosion resistance.

    Solution: Coating, surface treatment, and other methods can be used to improve the corrosion resistance of EMI specific copper powder.

EMI(Electromagnetic Interference)专用铜粉是一种高性能的导电材料,广泛应用于抑制电磁干扰和RFI(Radio Frequency Interference)等领域

EMI (Electromagnetic Interference) copper powder is widely used in fields such as suppressing electromagnetic interference and RFI (Radio Frequency Interference). The following are precautions to be taken when purchasing and using EMI specific copper powder:

  1. Choose products produced by reputable manufacturers: When purchasing EMI specific copper powder, it is recommended to choose products from reputable manufacturers. Legitimate manufacturers usually have complete production equipment and technology to ensure the quality and stability of their products.

  2. Pay attention to product quality and performance: The quality and performance of EMI specific copper powder directly affect its application effect in electronic devices. Therefore, it is necessary to carefully check the quality and performance parameters of the product when purchasing to ensure that it meets the requirements.

  3. Pay attention to storage conditions: EMI specific copper powder generally needs to be stored in low temperature, dry, and dark conditions to ensure its quality and stability. During storage, it is necessary to avoid moisture, exposure to sunlight, and contamination.

  4. Using the correct process parameters: When using EMI specific copper powder, it is necessary to use appropriate process parameters according to specific requirements. If the process parameters are incorrect, it may lead to a decrease in product quality or the inability to produce qualified products.

  5. Pay attention to safety during use: EMI specific copper powder is a fine-grained material that is prone to generating dust. When using, attention should be paid to protective measures and direct inhalation of dust should be avoided, which may have an impact on health.
