With the continuous development of the electronics industry, low-temperature conductive silver paste, as an important electronic material, has been widely used in fields such as flexible electronics, wearable devices, touch screens, and thin film switches. However, with the increasing market demand and technological requirements, the performance improvement and cost control of low-temperature conductive silver paste have become the focus of industry attention. This article will explore the continuous research and innovation directions of low-temperature conductive silver paste, and present the findings of Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand YB8601 Low Temperature Conductive Silver PasteFor example, demonstrate how to enhance competitiveness through technological innovation.

1、 Challenges faced by low-temperature conductive silver paste

Although low-temperature conductive silver paste has been applied in multiple fields, it still faces some challenges. For example, in some application scenarios, its conductivity performance cannot fully meet high-end requirementsHigh temperature sintered conductive silver pasteCompared to others, there may be a 10% -20% difference in conductivity. Meanwhile, due to limitations in raw materials and preparation processes, its cost is relatively high, which to some extent limits its large-scale application.

2、 Silver powder optimization

The particle size and shape of silver powder have a significant impact on the performance of low-temperature conductive silver paste. Research has shown that by accurately controlling the particle size of silver powder between 1-5 μ m and using a reasonable mixture of flake silver powder and spherical silver powder (such as flake silver powder accounting for 30% -50%), the bulk density of silver powder can be increased, thereby improving the conductivity of conductive silver paste.

Advanced Institute (Shenzhen) Technology Co., LtdSignificant progress has been made in the optimization of silver powder for YB8601 low-temperature conductive silver paste under the research platinum brand. It adopts a special preparation process to control the average particle size of silver powder at around 3 μ m, with flake silver powder accounting for about 40%, which increases the conductivity of the conductive silver paste by about 15% compared to traditional low-temperature conductive silver paste.

3、 Improvement of Adhesive System

Developing adhesives with lower curing temperatures, higher bonding strength, and better flexibility is an important direction for improving the performance of low-temperature conductive silver paste. Traditional adhesives such as polyurethane and epoxy resin have limitations in certain properties. The new organic-inorganic hybrid adhesive can provide a bonding strength 20% -30% higher than traditional adhesives at a curing temperature of 80-120 ℃.

The YB8601 low-temperature conductive silver paste of Yanbo brand adopts a self-developed new adhesive system, and its curing temperature can be as low as 85 ℃, which is about 10-15 ℃ lower than similar products. At the same time, the bonding strength has been increased by about 25%. This makes the conductive silver paste perform well in applications such as flexible circuit boards that require high temperature and bonding performance.

4、 Additive Innovation

Improving the purity of silver powder can reduce the impact of impurities on its conductivity.High purity silver powder(such as purity above 99.99%) can significantly improve the conductivity of conductive silver paste. For every 0.1% increase in silver powder purity, the resistivity of conductive silver paste can be reduced by about 5% -8%.

In addition, improving the interfacial adhesion between the binder and silver powder can enhance the overall performance of the conductive silver paste. Through surface modification techniques, such as coupling agent treatment of silver powder, the interfacial bonding force between silver powder and binder can be increased by 30% -50%, thereby improving the conductivity and mechanical properties of conductive silver paste.

Optimizing dispersants can make silver powder more evenly dispersed in the binder system. Efficient dispersants can reduce the agglomeration of silver powder by 30% -40%, thereby improving the conductivity of conductive silver paste.

5、 Innovation in preparation process

Advanced preparation techniques are crucial for improving the performance of low-temperature conductive silver paste and reducing costs. Through precise stirring and dispersion processes, it is possible to ensure that each component is fully dispersed, improving the purity and uniformity of the slurry. Meanwhile, optimizing production processes and controlling parameters can improve production efficiency and product quality.

6、 Market prospects and challenges

With the increasing global awareness of environmental protection, regulations on the disposal of electronic waste in various countries are becoming increasingly strict. The use of low-temperature conductive silver paste can reduce the energy consumption and waste emissions of electronic devices in the production process, which meets the requirements of environmental regulations and provides policy support for the development of the low-temperature conductive silver paste market.
