Optimizing the formula of high sintering copper paste for MLCC to improve the corrosion resistance of the sintered layer

With the rapid development of electronic technology, multi-layer ceramic capacitors (MLCC) are increasingly widely used in various electronic devices. The performance of MLCC depends not only on its design and manufacturing process, but also closely related to the materials used. As a key material for the internal electrodes of MLCC, the optimization of the formula of high-temperature copper paste plays a crucial role in improving the corrosion resistance of the sintered layer. This article will delve into how to optimize the formula of high sintering copper paste for MLCC to improve the corrosion resistance of the sintered layer, and introduce the research and development of Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum YB5112 MLCC High Temperature Copper PasteInnovative achievements in this field.

1、 The importance of optimizing corrosion resistance

MLCC plays an important role in electronic devices, including energy storage, filtering, and bypass. However, in complex and ever-changing usage environments, the sintered layer of MLCC may suffer from various forms of corrosion such as chemical corrosion and electrochemical corrosion, leading to a decrease in its performance or even failure. Therefore, improving the corrosion resistance of the sintered layer is crucial for ensuring the long-term stability and reliability of MLCC.

2、 Strategy for optimizing the formula of high sintering copper paste for MLCC

2.1 Choose high-quality copper powder

Copper powder is the main component of high sintered copper paste, and its quality directly affects the corrosion resistance of the sintered layer. Choosing copper powder with high purity, low oxygen content, and uniform particle size distribution can reduce defects during the sintering process, improve the density and uniformity of the sintered layer, and thus enhance its corrosion resistance.

2.2 Add appropriate corrosion-resistant additives

Adding an appropriate amount of corrosion-resistant additives, such as rare earth elements and organic silicon compounds, to the copper paste formula can effectively improve the corrosion resistance of the sintered layer. These additives can react chemically with copper powder during the sintering process, forming a dense protective film that prevents the erosion of corrosive media.

2.3 Optimize the ratio of glass powder and organic carrier

Glass powder and organic carrierHigh fever and copper paste formationIt plays a role in bonding and lubrication. By optimizing the ratio of glass powder and organic carrier, the rheological and sintering properties of copper paste can be improved, thereby enhancing the density and uniformity of the sintered layer and improving its corrosion resistance.

2.4 Precise control of sintering process parameters

The sintering process parameters also have a significant impact on the corrosion resistance of the sintered layer. By precisely controlling parameters such as sintering temperature, time, and atmosphere, it is possible to ensure that the copper paste is fully sintered, forming a dense and uniform sintering layer, thereby improving its corrosion resistance.
