Abstract
Description
technical field
[0001] The invention relates to an electronic paste, in particular to a preparation method for laser cutting conductive silver paste, low-temperature curing ultrafine spherical silver powder and each other. Background technique
[0002] Low-temperature curing silver paste is used for various substrates that can only withstand low-temperature baking. The substrate is generally plastic film (board) or paper film (board), and the material of plastic film (board) is generally PET, PI, PC, etc.; low-temperature curing silver paste can be used in computer keyboards, membrane switches, touch screens and other electronic products. Strict requirements; the existing low-temperature curing silver paste for screen printing can generally only print lines with a width of 60 microns and a line spacing of 60 microns (commonly known as 60 / 60 lines), which cannot meet the current market requirements for electronic products ( Thin lines with a width of 20-25 microns can meet t...
