Basic principles, preparation methods, application areas, and purchasing precautions of silver palladium conductive paste

1、 Basic principles
        Silver palladium conductive pasteThe basic principle is to utilize the excellent conductivity of silver and palladium, two conductive metals, to form a conductive liquid by mixing and suspending them in a medium oil, and to achieve conductivity through coating or printing. Among them, silver powder is the main conductive material, while palladium plays a role in enhancing conductivity and stability.
2、 Preparation method
There are two main methods for preparing silver palladium conductive paste: dry method and wet method.
Dry method preparation: First, mix silver powder and palladium powder evenly in a certain proportion, then add auxiliary materials such as base agents and additives for mixing, and finally obtain silver palladium conductive paste through high-temperature calcination and other processes.
Wet preparation: Silver ions, palladium ions, and reducing agents are mixed and suspended in a medium oil. After reduction reaction, they are reduced to silver powder and palladium powder. Finally, auxiliary materials such as additives are added to obtain silver palladium conductive paste. Among them, the wet preparation method can achieve control and adjustment of the particle size of the conductive liquid, thus having higher accuracy.
3、 Application Fields
        Silver palladium conductive pasteIt has a wide range of applications in the electronics industry, and the following are several common application areas:
Welding: Silver palladium conductive paste can be used as a welding material, which can heat the metal surface to the melting point through Joule heating effect at high temperatures to achieve effective welding.
Electronic components: Silver palladium conductive paste can be used to make various shapes of electronic components such as resistors, capacitors, contacts, etc., which are used in fields such as circuit boards and semiconductor devices to achieve precise control of current and voltage.
