Is the conductivity of low-temperature conductive silver paste affected by temperature changes?

With the rapid development of electronic technology, low-temperature conductive silver paste has been widely used as an important connecting material in fields such as displays, chip packaging, LED lights, and solar cells. However, in practical applications, temperature changes often have an impact on the performance of conductive materials. This article will be developed by Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand YB6016 Low Temperature Conductive Silver AdhesiveFor example, explore the changes in its conductivity under different temperature conditions and conduct a detailed analysis based on experimental data.

Basic composition and characteristics of low-temperature conductive silver paste

YB6016 low-temperature conductive silver paste from Yanbo brand is mainly composed of matrix resin, conductive filler (such as silver powder and graphene mixture), curing agent, stabilizer, promoter, anti precipitation agent, and silane coupling agent. Its special formula design enables the conductive silver adhesive to quickly cure at lower temperatures while maintaining excellent conductivity and bonding properties. For example, the silver paste can be completely cured within 45 minutes at 75 ℃, and its electrical resistivity and bonding strength remain stable at different temperatures.

Experimental Design and Methods

In order to conduct researchResearch Platinum Brand YB6016 Low Temperature Conductive Silver AdhesiveWe designed a series of experiments to test the electrical resistivity and bonding strength of the silver paste under different temperature conditions (including room temperature of 25 ° C, -10 ° C, -20 ° C, -30 ° C, and -40 ° C) to determine whether its conductivity is affected by temperature changes. The experiment selected standard metal substrates (such as copper, aluminum, iron, nickel, and tin) as test objects to ensure the wide applicability of the results.

experimental procedure

1. Sample preparation: Apply YB6016 low-temperature conductive silver paste from Yanbo brand uniformly onto the selected metal substrate surface and cure it according to standard procedures.
2. Electrical resistivity testing: Use a high-precision electrical resistivity tester to measure the electrical resistivity of metal substrates coated with conductive silver paste under different temperature conditions.
3. Adhesive strength test: Measure the adhesive strength between conductive silver adhesive and metal substrate through a tensile testing machine.

Experimental results and analysis

resistivity variations

The experimental results show that the resistivity of YB6016 low-temperature conductive silver paste from Yanbo brand changes little at different temperatures. Specifically, at a low temperature of -40 ° C, its resistivity only increased by about 10% compared to room temperature (25 ° C). In contrast, someOrdinary conductive silver adhesiveThe increase in resistivity at -20 ° C can reach 30% to 50%. This indicates that YB6016 can maintain good electronic conductivity at low temperatures.

Adhesive force variation

In terms of adhesion, the YB6016 brand from Yanbo also performs well. At a low temperature of -30 ° C, its adhesion to materials such as ceramics and metals decreased by only 5% to 10% compared to room temperature, which is much lower than the 20% to 40% decrease of ordinary conductive silver paste. This is due to its special formula design, which allows the polymer matrix to maintain good flexibility and intermolecular forces at low temperatures.

The Influence Mechanism of Temperature on Conductivity

The influence of low temperature on the conductivity of conductive silver paste mainly comes from two aspects: firstly, the movement and contact of conductive particles are restricted to a certain extent at low temperature, resulting in local obstruction of the electronic conduction path; Secondly, low temperature makes the polymer matrix of silver paste harder, reducing its wettability and intermolecular forces on the surface of the bonded material, thereby affecting the bonding performance. However, by optimizing the formula design, the YB6016 brand from Yanbo has effectively alleviated these adverse effects and maintained good conductivity and bonding performance.

Conclusion and Prospect

in summary,Research Platinum Brand YB6016 Low Temperature Conductive Silver AdhesiveThe conductivity of the material is less affected by temperature changes, and it can still maintain good conductivity and bonding performance in low-temperature environments. This characteristic makes it have broad application prospects in temperature sensitive scenarios such as aerospace and electronic devices in extremely cold regions. In the future, with the continuous development of electronic manufacturing technology, the application scope of low-temperature curing silver paste will be further expanded. Enterprises and research institutions should continue to explore new formula designs and technological optimizations to meet the needs of different application scenarios and promote the wider application of conductive silver adhesives in low-temperature environments.
