Description

technical field [0001] The invention relates to an ink, in particular to a conductive ink. Background technique [0002] Conductive ink, a paste ink made of conductive materials (gold, silver, copper and carbon) dispersed in a binder, commonly known as paste ink. It has a certain degree of conductive properties and can be used for printing conductive points or conductive lines. Gold-based conductive inks, silver-based conductive inks, copper-based conductive inks, and carbon-based conductive inks have been put into practical use for printed circuits, electrodes, electroplating bottom layers, keyboard contacts, and printed resistors. [0003] Conductive ink refers to the ink that is printed on conductive substrates to enable it to conduct current and eliminate the ability to accumulate static charges. It is generally printed on non-conductive substrates such as plastic, glass, ceramics or cardboard. There are a wide range of printing methods, such as screen printing, letter...
