The conductive ink is a composite material consisting of conductive filler, an adhesive, a solvent and an auxiliary agent, wherein the conductive filler is dispersed in the adhesive to form composite conductive particles, and a conductive circuit can be printed on a flexible or rigid substrate to prepare the printed circuit board. The key functional phase of the conductive ink is conductive filler, and the conductive ink can be divided into inorganic systems, organic systems and composite systems according to the difference of the conductive filler. The traditional carbon-based conductive ink takes graphite, carbon fiber and a mixture thereof as main fillers, belongs to the class of inorganic systems, and has the advantages of low cost, stable performance, high cost performance and the like; inorganic nano-metal conductive ink and organic conductive ink have better conductivity, and gradually replace the traditional carbon conductive filler. However, the novel carbon-based conductive ink prepared by using the carbon nanotubes and the graphene as the conductive filler has the advantages of higher conductivity, better mechanical strength, lighter weight, lower cost, greater research and development prospect and higher market value.
The method of printing flexible circuit boards using conductive inks is a common method. A flexible circuit is a special circuit formed by mounting electronic components on a flexible substrate, which is usually made of a polymer material and has the characteristics of light weight, thin thickness, flexibility and bending. The flexible circuit board has wide application in the fields of smart phones, wearable equipment, automotive electronics and the like. The process of printing the flexible circuit board is various and comprises the steps of substrate laser printing, circuit printing, plate shearing, electronic element connection, packaging and the like. Most of the existing flexible circuit printers are in a jet printing mode, a plurality of micro nozzles are integrated into a multi-channel industrial nozzle, and then the printing process is realized by controlling ink jet of each nozzle and the movement of the multi-channel nozzle. This printing method has many ink paths and high efficiency, but is costly, and requires manual inspection of the circuits and connection of electronic components for printing of most complex circuits. Therefore, a flexible circuit printer capable of realizing human-computer interaction function and economy is needed to meet the printing and detection requirements of complex flexible circuits.
