3D printer set for quickly manufacturing PCB (printed circuit board)

Abstract

The invention relates to a 3D printer set for quickly manufacturing a PCB (printed circuit board). The 3D printer set comprises three-dimensional drilling spray needle equipment, three-dimensional ink-jet character equipment and three-dimensional press fit equipment. Novel 3D printing equipment based on a digital inkjet technology uses materials such as nano liquid metal, photosensitive resin and the like to manufacture the PCB. The 3D printer set is integrated with punching, silver depositing, line spraying, coating and lettering, so that the whole producing and manufacturing process of the PCB can be completed by only needing one set of equipment, and therefore, the producing process is greatly simplified; ink-jet printing speed is greater than electroplating and etching speed by more than 20 times, so that total process time is saved by more than 60%, producing and manufacturing time is greatly shortened, and reliability is also remarkably improved; functional printing ink is used for jet printing so as to obtain a printed line, a resistance welding layer and a character layer for manufacturing the PCB, and therefore, a material utilization rate is close to 100%, energy consumption is lower, cost is lower, and green production is realized; and the functional printing ink is adopted to directly carry out jet printing on an insulated base plate so as to obtain the printed line, the resistance welding layer and the character layer, so that a printing ink utilization rate is close to 100%, and almost no-pollution emission is realized.
