The full name of the screen printing machine is the "screen printing machine", which is a device that prints solder paste or patch glue onto the PCB pads through the screen. Mainly used in the electronic processing industry, the silk screen logo of printed circuit boards, the logo of the instrument shell panel, the solder paste printing in the process of circuit board processing, etc. Screen printing machines are divided into vertical screen printing machines, inclined arm screen printing machines, rotary screen printing machines, four-column screen printing machines and automatic screen printing machines.

　　Modern screen printing machines generally consist of plate loading, inking, embossing, paper feeding (including folding) and other mechanisms. Its working principle is: first make the text and image to be printed into a printing plate, install it on the printing machine, and then apply the ink to the place where the text and image are on the printing plate manually or by the printing machine, and then directly or indirectly transfer it. Print on paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics) to replicate the same printed matter as the printing plate.

　　The characteristics of vertical screen printing machine: for high-precision printing, such as high-tech electronics industry, multi-color overprinting, dot printing, etc. Compared with the oblique arm screen printing machine, the efficiency is low, but the accuracy is high; the characteristics of the oblique arm screen printing machine: for the packaging industry, or partial UV printing, high efficiency, but low accuracy; the characteristics of the rotary screen printing machine: for the clothing industry, Or the optical disc industry, the industry that is not well positioned can adopt the turntable type; the characteristics of the four-column screen printing machine: for large-area industries, such as decoration, large glass and other industries.

　　The characteristics of the automatic screen printing machine: it is roll-to-roll printing for soft materials such as PET, PP, PC, PE, etc. It is completed by the integrated process of feeding, printing and drying, which is the best for mass production. Choice; Features of automatic elliptical screen printing machine: It is mainly suitable for printing garment pieces, and can print glue, water slurry, ink and other slurries.
