Description

technical field [0001] The invention relates to a photosensitive conductive silver electrode paste and a preparation method thereof. Background technique [0002] Conductive silver electrode paste is a kind of electrode paste, which is widely used in semiconductor integrated circuits, light-emitting diodes, plasma display panels, liquid crystal displays, organic light-emitting screens, printed circuit boards, quartz crystal resonators, light-emitting devices, stone mills, etc. In many fields such as electrodes, touch switch circuits, and electrodes of key components, the use of conductive silver electrode paste can not only ensure the connection quality of the circuit, but also improve the accuracy of the circuit connection and reduce the manufacturing cost of electronic components. [0003] The conductive silver electrode paste is generally made into a fixed shape by printing or coating the original paste, and then printed or coated on the electrode plate of the electronic ...

AI Technical Summary

Problems solved by technology

In the occasions where sintering cannot be carried out due to the substrate or other materials that are not resistant to high temperature, only photosensitive conductive silver electrode paste can be used.

[0004] So far, most silver electrode pastes use sintering process to form electrodes, which requires higher temperature, wastes energy, and does not meet the current energy saving requirements; The method to reduce costs, adding silver-coated glass powder and other ingredients, resulting in a decrease in electrical conductivity, discontinuous electrodes, and easy power failure results
