Medium temperature silver paste is a common conductive material widely used in the field of electronics

1、 Introduction
        Medium temperature silver pasteIt is a common conductive material widely used in the field of electronics. It has advantages such as good conductivity, corrosion resistance, and high temperature stability, and is used in fields such as printed circuit boards and solar cells.
2、 Preparation method
There are two main methods for preparing medium temperature silver paste: chemical reduction method and physical vapor deposition method.
Chemical reduction method
Chemical reduction method refers to the use of reducing agents to reduce silver ions into silver particles. This method requires the use of reducing agents, surfactants, stabilizers, and other materials, which are mixed with silver ions and subjected to certain reaction conditions to prepareMedium temperature silver paste.
This method has the advantages of simple preparation process and easy availability of raw materials, but it requires control of reaction conditions, otherwise it will affect the performance of the prepared silver paste.
Physical vapor deposition method
Physical vapor deposition method refers to the method of depositing silver atoms on a substrate using physical vapor deposition technology to form a silver film. This method requires the use of gas sources, inert atmospheres, substrates, and other materials, which are placed under certain reaction conditions. After the reaction, a medium temperature silver paste can be prepared.
This method does not require the use of organic solvents in the preparation process, and has the advantages ofSilver pasteAdvantages such as stable quality, but require special equipment and high costs.
