This article will explore the characteristics of pressureless sintered silver paste and introduce the research achievements and technical solutions of Advanced Institute (Shenzhen) Technology Co., Ltd. in this field, especially itsYanbo brand pressureless sintered silver paste.

2、 Basic characteristics of pressureless sintered silver paste

The pressureless sintered silver paste is mainly composed of nano silver particles, organic carriers, and additives. Its basic characteristics include:

1. Viscosity: Viscosity is a key indicator for measuring the flowability of pressureless sintered silver paste. Excessive viscosity can affect the flowability of materials, leading to difficulties in process operations such as dispensing and screen printing; If the viscosity is too low, it may cause excessive diffusion of the material during operation, affecting the quality of the finished product.

2. Liquidity: Liquidity refers to the ability of pressureless sintered silver paste to flow under external forces. Good fluidity helps to evenly distribute materials in processes such as dispensing and screen printing, improving the consistency and reliability of the finished product.

3. Thixotropy: Thixotropy refers to the viscosity change characteristics of pressureless sintered silver paste under shear force. Good thixotropy helps materials maintain a stable shape during processes such as dispensing and screen printing, avoiding adverse phenomena such as tailing and wire drawing.

4. Stability: Stability refers toPressureless sintered silver pastePerformance changes during storage and use. Good stability helps materials maintain consistent performance during long-term storage and use, improving the reliability and lifespan of finished products.

3、 Application of pressureless sintered silver paste in process operations such as dispensing and screen printing
