MLCC, or multilayer ceramic capacitor, is a key component widely used in electronic devices, and its performance directly affects the overall performance of electronic products. As the main material of the internal electrode of MLCC, conductive copper paste, its conductivity, stability and compatibility with other materials directly affect the performance and reliability of MLCC.

As the main material of the internal electrode of MLCC, conductive copper paste, its conductivity, stability and compatibility with other materials directly affect the performance and reliability of MLCC.

1. The conductivity of conductive copper paste is a key factor in MLCC manufacturing. The working principle of MLCCs depends on the electric field distribution and charge storage between their internal electrodes, and conductive copper paste, as the main material of the internal electrodes, must have good conductivity to ensure that the charge can be transferred between the electrodes quickly and effectively. The resistivity, conductivity uniformity and interface resistance with ceramic dielectric are also important factors affecting the performance of MLCC, and the preparation process, composition selection and microstructure control of conductive copper paste need to be strictly designed and optimized to meet the high requirements of MLCC for conductivity.

2. The stability of conductive copper paste is an important guarantee to ensure the long-term reliable operation of MLCC. MLCCs experience a variety of environmental conditions during production and use, such as temperature changes, humidity changes, electric field strength changes, etc. As the internal structure of MLCCs, conductive copper paste must have good stability to ensure that stable electrical and mechanical properties can be maintained under harsh environmental conditions. This requires conductive copper paste not only to have good initial properties, but also to have excellent anti-aging properties, anti-corrosion properties and anti-mechanical stress properties.

3. The compatibility of conductive copper paste with other materials is also a problem that cannot be ignored in the manufacture of MLCC, the manufacturing of MLCC involves the combination and processing of a variety of materials, such as ceramic dielectric, internal electrode electrode, etc., conductive copper paste as the main material of the internal electrode, must have good compatibility with other materials, no chemical reaction, interface failure and other problems will occur in the manufacturing process, and the preparation process of conductive copper paste should also be coordinated with the overall manufacturing process of MLCC to ensure production efficiency and quality stability.

4. The preparation cost of conductive copper paste is also an important factor to be considered in the manufacture of MLCC, the preparation of conductive copper paste involves many aspects such as raw material selection, process design, equipment investment, etc., and the cost is relatively high, so it is of great significance to reduce the preparation cost of conductive copper paste to improve the market competitiveness of MLCC under the premise of ensuring conductive performance, stability and compatibility. This can be achieved by optimizing the preparation process, improving the material utilization rate, and developing new low-cost conductive materials.

As an indispensable part of MLCC manufacturing, conductive copper paste, its conductivity, stability, compatibility with other materials and preparation cost directly affect the performance and reliability of MLCC. This requires us to continuously research and develop new conductive copper paste materials and technologies to meet the needs and challenges of MLCC manufacturing in the future.
