Dendritic copper powder is a type of particle with a branched structure, characterized by high purity and fine particle size. Due to its unique morphology and excellent electrical conductivity, dendritic copper powder finds extensive applications in the field of high-end electronics.


Firstly, dendritic copper powder is used as a major component in high-performance conductive pastes. By combining dendritic copper powder with conductive material substrates, highly conductive materials for printed circuit boards, conductive adhesives, strain sensors, and other areas can be prepared. Its high electrical conductivity and superior contact properties make it an ideal conductive material for high-frequency electronic devices and microelectronic components.

Secondly, dendritic copper powder has significant applications in high-end electronic packaging. By incorporating dendritic copper powder into thermal pastes, the heat dissipation performance of electronic components can be significantly enhanced, thereby improving device stability and longevity. Additionally, dendritic copper powder can be used to produce highly conductive soldering materials for the connection and packaging of electronic components, ensuring reliable circuit connections and reliability.

Furthermore, dendritic copper powder is widely employed in electronic drawing and conductive coatings. Its small particle size and branched structure enable precise drawing lines and uniform conductive coatings with excellent conductivity. This has important applications in flat panel displays, flexible electronics, touch screens, and optoelectronic devices, providing reliable conductive surfaces and excellent sensing performance.
