The main function of spherical silver coated copper powder is as a conductive material and microelectronic packaging material

Spherical silver coated copper powder is a metal powder material composed of copper particles coated with a thin layer of silver on their surface. Its main use is as a conductive material and microelectronic packaging material in the electronics industry.

The origin and background of this material can be traced back to the 1960s, when the demand for high-performance conductive materials in the electronics industry was increasing. However, traditional materials such as copper and aluminum had problems such as high electrical resistivity and poor corrosion resistance. So scientists began to study how to improve the properties of these materials and found that coating silver on the surface of copper particles could significantly enhance their conductivity and corrosion resistance. This gave birth to spherical silver coated copper powder.

After years of development and improvement, spherical silver coated copper powder has become an important electronic material. It is widely used in fields such as printed circuit boards, conductive capsules, and reliable soldering materials, and has been continuously improved and optimized to meet the material performance requirements of high-performance electronic devices.

The main function of spherical silver coated copper powder is as a conductive material and microelectronic packaging material. It has the following advantages in the electronics industry:

1. Excellent conductivity: The surface of spherical silver coated copper powder is covered with a layer of silver, which greatly improves its conductivity, making it more conductive than traditional materials such as copper and aluminum.

2. Good corrosion resistance: The presence of silver layer can improve the corrosion resistance of copper particles, thereby extending the service life of the material.

3. Good processability: The spherical silver coated copper powder has uniform particle size and is not easy to aggregate, making it easy to process into various shapes and sizes during the preparation process.

4. Cost saving: Compared to pure silver materials, the cost of spherical silver coated copper powder is lower, and its conductivity and corrosion resistance have also been greatly improved.

5. Easy to combine with other materials: Spherical silver coated copper powder can be easily combined with other materials such as resin, glue, etc., to facilitate its use in electronic components.
