Squeegee may seem simple, but in fact squeegee is a very complex part of screen printing.In other forms of printing, to make inks The transfer tools are squeegee, ink roller, pressure roller and glue, each of which has its own unique function.In screen printing, the functions of squeegee are mainly in the following four aspects: 1. Transfer the ink through the screen to the substrate. 2. Scrape the excess ink off the screen. 3. Keep the screen in contact with the subst
Development status and trend of screen printing machine at home and abroad Development status and trend of screen printing machines abroad Since the early 1940s, the international screen printing industry has developed rapidly depending on the production of photosensitive plate making technology.In the 1960s, the emergence and rapid development of a variety of high-end industries once again promoted the overall development of screen printing technology and special equipment and ma
Screen printing and screen printing machine Screen printing is a type of hole printing. Screen printing involves stretching a mesh of fabric over a screen frame and making a plate for printing.Perforated plate printing includes hollowed-out plate, as soon as possible, spray plate and jie jie printing method. Jie Jie printing method is screen printing. Screen printing method is most widely used in hole printing industry.Compared with other printing methods, screen printing is outstanding in the
Production technology of electrode mesh plate The screen plate of screen printing consists of screen frame, screen and mask pattern.The screen is stretched on the screen frame, and then coated with mask graphics, using photographic etching method to produce the graphics on the screen. screen frame The screen frame is used to fix the screen, and the relative position between the screen and the printing base is fixed during screen printing. 1. Selection of screen f
Silk screen printing The screen printing process of solar cells USES the screen printing method to complete the production of back field, back electrode and positive grid wire metal electrode, so as to lead out the generated current.The screen printing process has three purposes. 1) Electrode printing is carried out on the silicon wafer behind the P-N junction and $film. 2) The carrier generated by the light can be successfully exported to realize photoelectric conversion of
The parameters affecting the accuracy of screen printing, mainly mentioned the screen's geometric characteristics, ink these two most important factors.The screen geometry characteristic is the foundation of screen printIng.Based on the analysis of mesh number and diameter, the calculation formula of minimum mesh point is compared, and it is proposed that the resolution calculation should be carried out under the influence of tension, so as to obtain more accurate results.The surface conditio
