Improve the antioxidant performance of conductive silver paste in integrated circuits

Integrated Circuit Conductive Silver AdhesiveAs a key material in electronic packaging, its antioxidant performance is crucial for ensuring the stable operation of circuits and extending the lifespan of electronic products. This article will explore how to improve the antioxidant performance of conductive silver paste in integrated circuits from multiple perspectives.

1、 Optimize material formula

1. Add antioxidant

   • Adding an appropriate amount of antioxidants to the formula of conductive silver paste can effectively delay the oxidation process of silver. Antioxidants can capture free radicals and prevent them from reacting with silver, thereby forming a protective layer and reducing the formation of silver oxide film.

2. Improve polymer purity

   • The purity of polymers (such as resins) in conductive silver paste has a significant impact on their antioxidant properties. High purity polymers can reduce the introduction of impurities and lower the risk of electrochemical corrosion. Heating and dehumidifying the matrix resin before mixing is also an effective method to further reduce the moisture content and improve the antioxidant performance.

2、 Improve the preparation process

1. Refine silver particles

   • The use of ultrasonic dispersion technology to further refine silver particles can improve the density of the conductive network and reduce electrical resistivity. Refined silver particles can be more evenly distributed in the polymer matrix, reducing oxidation points and thus improving antioxidant performance.

2. Optimize curing conditions

   • Curing isConductive silver adhesiveThe key step in forming a stable structure. By adjusting the curing temperature and time reasonably, the silver paste can be cured in the optimal state, which can enhance its mechanical strength and electrical properties, thereby improving its antioxidant capacity.

3、 Using special additives

1. Adding deoxidizer

   • Adding a deoxidizer to the conductive silver paste allows it to react with oxygen that diffuses into the conductive paste, thereby reducing oxygen concentration and delaying the occurrence of electrochemical corrosion.

2. Add corrosion inhibitor

   • Corrosion inhibitors can form chelates with the anode metal, surrounding the metal surface and inhibiting corrosion reactions. Choosing appropriate corrosion inhibitors is crucial for improving the antioxidant properties of conductive silver paste.

4、 Enhanced protective coating

1. Apply protective coating

   • If necessary, a protective coating with strong barrier properties can be applied to the surface of conductive silver paste. This coating can effectively prevent the invasion of external moisture and the diffusion of oxygen, thereby extending the service life of conductive silver paste.

5、 Packaging and Storage Strategy

1. Using sealed packaging

   • Reducing the impact of environmental factors on conductive silver adhesive products through sealed packaging is particularly important, especially in products stored for a long time. Sealed packaging can effectively prevent the invasion of air and moisture, and maintain the stability of conductive silver paste.

2. Control storage conditions

   • During storage, temperature and humidity should be controlled to avoid adverse effects on conductive silver paste in high temperature and high humidity environments. At the same time, regularly check the storage conditions to ensure that the conductive silver paste is in the best condition.
