Addressing the issue of decreased performance of conductive silver paste in low-temperature environments

Brief introduction

Conductive silver paste plays a crucial role in the connection and conductive applications of many electronic devices. However, in low-temperature environments, its performance often deteriorates, which poses challenges for some equipment that needs to operate under low-temperature conditions. This article will explore how to solve the problem of performance degradation of conductive silver paste in low-temperature environments, and refer to the relevant research results of Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum YB6016 Low Temperature Conductive Silver AdhesiveAnalyze as an example.

2、 Performance degradation of conductive silver paste under low temperature environment

1. Decreased conductivity
   • In low temperature environments, ordinaryConductive silver adhesiveThe resistivity may significantly increase. For example, according to [relevant research data], in an environment of -20 ° C, the resistivity of certain ordinary conductive silver adhesives increases by 30% -50% compared to room temperature (25 ° C). This is because low temperatures can affect the movement and contact of conductive particles inside the silver paste, hindering electronic conduction.
2. Weakened adhesion
   • Experimental data shows that when the temperature drops to -10 ° C, the bonding strength of some conductive silver adhesives to certain materials (such as ceramics and metals) will decrease by 20% -40%. This is because low temperature makes the polymer matrix of silver paste harder, reducing its wettability and intermolecular forces on the surface of the bonded material, resulting in a decrease in bonding performance.

3、 Characteristics of YB6016 low-temperature conductive silver paste for platinum research

1. Conductivity at low temperatures
   • Advanced Institute (Shenzhen) Technology Co., LtdResearchers conducted tests on the low-temperature conductive silver paste YB6016 made of platinum. At a low temperature of -40 ° C, the resistivity of YB6016 platinum only increased by about 10% compared to room temperature (25 ° C). This has significant advantages compared to ordinary conductive silver paste, indicating that YB6016 can maintain good electronic conductivity at low temperatures.
2. bond
   • Through experiments, it was found that under low temperature conditions of -30 ° C, the bonding strength of YB6016 to ceramic and metal materials decreased by only 5% -10% compared to room temperature. Compared with ordinary conductive silver paste, the decrease in bonding strength is significantly smaller, thanks to the special formula design of YB6016, which can maintain good flexibility and intermolecular forces of its polymer matrix at low temperatures.

4、 Measures to address the degradation of conductive silver paste performance in low-temperature environments

1. Select suitable low-temperature conductive silver adhesive
   • From the above data comparison, it can be seen that conductive silver paste designed specifically for low-temperature environments, such as YB6016, is the key to solving the problem. Enterprises and research institutions should prioritize such applications in low-temperature environmentsLow temperature conductive silver adhesiveFor example, in a project where an electronic device needs to work in an environment of -30 ° C, the use of YB6016 platinum instead of ordinary conductive silver paste significantly improved the conductivity and connection performance of the device, reducing the failure rate by 30%.
2. Optimize the usage process of silver adhesive
   • The curing process of silver paste also needs to be optimized in low-temperature environments. Research by Advanced Institute (Shenzhen) Technology Co., Ltd. shows that increasing the curing temperature appropriately (within the allowable range of materials) can improve the performance of silver paste at low temperatures. For example, willResearch Platinum YB6016After increasing the curing temperature from the standard 80 ° C to 90 ° C, the electrical resistivity further decreased by about 5% and the bonding strength increased by about 3% in an environment of -20 ° C.
   • Meanwhile, it is also crucial to ensure the cleanliness and appropriate roughness of the bonded surface during the adhesive application process. If the surface roughness increases, the contact area between YB6016 and the bonded surface will increase, and the bonding force at low temperatures can be improved by 8% -10% (based on experimental data from Advanced Institute (Shenzhen) Technology Co., Ltd.).
3. Control the usage environment
   • If possible, perform local temperature control on the use and working environment of conductive silver paste. For example, in some aerospace equipment, maintaining the temperature around conductive silver paste at a relatively high level (such as -10 ° C or above) through heating devices can effectively avoid the impact of low temperatures on its performance. According to simulation experiments, under this local temperature control, the performance degradation of ordinary conductive silver paste can be reduced from 50% to 10% -15%.

5、 Conclusion

In summary, the decrease in the performance of conductive silver paste in low-temperature environments is a problem that needs to be taken seriously. By selecting low-temperature conductive silver paste like YB6016, optimizing the usage process, and controlling the usage environment, this problem can be effectively solved. The research achievements of Advanced Institute (Shenzhen) Technology Co., Ltd. in this area provide us with good reference and inspiration, which will help promote the wider application of conductive silver paste in low-temperature environments.
