（1） Factors affecting service life

1. Ambient Temperature
   • The service life of low-temperature conductive silver paste is closely related to the working environment temperature. In high temperature environments, the resin matrix in silver paste may accelerate aging, leading to a decrease in conductivity and adhesion performance. Experimental data shows that when the working environment temperature exceeds 100 ° C,Research Platinum Brand YB6016 Low Temperature Conductive Silver AdhesiveThe conductivity may decrease by 20-30%, and the adhesive strength may also show a significant decrease.
2. humidity
   • Humidity is another important factor affecting the service life of low-temperature conductive silver paste. 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. Stress effect
   • 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.

（2） Strategies for extending service life

1. Choose appropriate 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 the YB6016 low-temperature conductive silver adhesive of Yanbo brand, it is recommended to bake at 80 ° C for 36 minutes to achieve the best curing effect.
2. Optimize the working environment
   • Try to place electronic devices in an environment with suitable temperature and low humidity to extend the service life of low-temperature conductive silver paste. For electronic devices that need to operate in high temperature or high humidity environments, additional protective measures such as installing heat dissipation devices or humidity controllers can be considered.
3. Improve the quality of the adhesive interface
   • The quality of the adhesive interface directly affectsLow temperature conductive silver adhesiveThe service life. During the bonding process, it is necessary to ensure that the surface of the substrate is clean, free of impurities such as oil stains and oxides, in order to improve the bonding strength between the silver adhesive and the substrate. Meanwhile, adopting appropriate bonding techniques and parameters can also improve the quality of the bonding interface.
