Description

technical field

[0001] The invention belongs to conductive ink, in particular to an ink-jet printing conductive ink that can be sintered at room temperature, and an application of the ink-jet printing conductive ink. Background technique

[0002] In recent years, the rapid development and increasing popularity of electronic information technology has been obvious to all. At the same time, the market demand for conductive circuits as the main material carrying part of electronic technology has reached 200 billion US dollars per year. At present, the circuit manufacturing technology still stays at the traditional technology level, mainly including photolithography, chemical etching, evaporation and silk screen printing. However, the traditional circuit manufacturing technology has inevitable defects such as high pollution, high waste, and high cost.

[0003] Compared with the process of preparing conductive circuits on conventional printed circuit boards, the method of prepar...
