Analysis results of service life of low-temperature conductive silver paste in electronic devices

With the continuous development of electronic technology, low-temperature conductive silver paste, as a high-performance conductive material, plays an increasingly important role in the packaging and connection of electronic devices. Low temperature conductive silver paste has become an ideal choice to replace traditional welding methods due to its excellent conductivity, low-temperature curing characteristics, and good adhesive properties. However, the service life of low-temperature conductive silver paste in electronic devices is affected by various factors, including working environment temperature, humidity, and stress. This article will provide a detailed analysis of the service life of low-temperature conductive silver paste in electronic devices, with a special mention of Advanced Institute (Shenzhen) Technology Co., LtdYanbo brand low-temperature conductive silver adhesive.

Basic characteristics of low-temperature conductive silver paste

Low temperature conductive silver adhesive is a conductive adhesive composed of silver powder, resin matrix, solvent, and additives. It can achieve good conductive connections at lower temperatures (usually much lower than traditional welding or sintering temperatures). Low temperature conductive silver paste has the following significant characteristics:

1. Low temperature curing: It can achieve rapid curing without damaging the substrate or electronic components.
2. Good conductivity: Due to the high proportion of silver powder, low-temperature conductive silver paste has excellent conductivity.
3. High reliability: The cured low-temperature conductive silver paste has stable conductivity and good mechanical strength.
4. Easy to process: It can be processed through methods such as dispensing and printing, and is suitable for various complex electronic structures and devices.

Analysis of the service life of low-temperature conductive silver paste in electronic devices

1. The impact of working environment temperature

Experimental data shows that when the working environment temperature exceeds 100 ° C,Low temperature conductive silver adhesiveThe conductivity may decrease by 20-30%, and the adhesive strength may also show a significant decrease. Therefore, in high-temperature environments, the resin matrix in silver paste may accelerate aging, leading to a decrease in conductivity and adhesion performance.

2. The impact of humidity

In high humidity environments, the moisture in silver paste may promote oxidation and corrosion of silver particles, thereby reducing conductivity. Meanwhile, humidity may also cause delamination or peeling at the bonding interface between silver paste and substrate.

3. The effect of stress

Electronic devices are often subjected to various stresses during operation, such as mechanical stress, thermal stress, etc. These stress effects may cause microcracks or damage to the bonding interface between silver paste and substrate, thereby affecting its service life.

4. The influence of curing conditions

The curing temperature and time have a significant impact on the performance and service life of low-temperature conductive silver paste. Choosing appropriate curing conditions can ensure complete curing of silver paste while reducing performance degradation caused by improper curing. For example, forResearch Platinum Brand YB6016 Low Temperature Conductive Silver AdhesiveIt is recommended to bake at 80 ° C for 36 minutes to achieve better curing effect.

Strategies for extending the service life of low-temperature conductive silver paste

In order to extend the service life of low-temperature conductive silver paste in electronic devices, the following strategies can be adopted:

1. Optimize working environment: Try to place electronic devices in an environment with suitable temperature and low humidity for operation.
2. Adopting protective measures: For electronic devices that need to work in high temperature or high humidity environments, additional protective measures such as installing heat dissipation devices or humidity controllers can be considered.
3. Choose appropriate curing conditions: Ensure that the silver paste is completely cured while reducing performance degradation caused by improper curing.
4. Improving the quality of the bonding interface: By optimizing the bonding process and improving the quality of the bonding interface, the bonding force between the silver adhesive and the substrate can be enhanced, thereby extending the service life.
