The Composition of Thin Film Switch Conductive Ink

1. Conductive inks are widely used in thin film switch applications


As a kind of printing material for printing, conductive ink is also widely used in the production of thin film switches. Because its appearance is a viscous paste, it is customarily called conductive paste, such as conductive silver paste, conductive carbon paste, and conductive nickel paste.


Conductive ink is often used in conjunction with the screen printing method of thin film switches. It has the printability of general screen printing inks, but it is very different from general screen printing inks. After the commonly used screen printing ink is dried, the ink film is the insulator for printing, while the conductive ink has obvious conductivity.


Due to the special functionality of the conductive ink, the performance varies with the composition of the ink, which results in different types of products with different characteristics.


2. Composition of conductive ink for thin film switch


The structure of conductive ink is a composite material composed of conductive fillers, binders, solvents, and additives.


In the structure and composition of conductive ink, due to the difference of specific substances, products with different characteristics can be produced. For example, when silver powder is used as conductive filler and glass powder is used as connecting material, high-temperature sintered silver ink is formed at this time; when the connecting structure is changed to photosensitive resin, light-solid conductive silver ink is formed.
