The Application and Influence Analysis of Domestic Screen Printing Technology in Electronic Industry

Screen printing belongs to stencil printing, which is called four printing methods together with plain printing, embossing, and gravure printing. Stencil printing includes stencil printing, stencil printing, spray printing, and screen printing. The principle of stencil printing is: the printing plate (the aperture of the printing plate or other printing plate can be used to make the ink through the hole) at the time of printing, the ink is transferred to the substrate (paper, ceramic, etc.) through the hole of the stencil through a certain pressure. ), forming an image or text.

During the printing, the squeegee presses the ink through the mesh part of the graphic part and transfers it to the printing material to form the same image as the original. Screen printing equipment is simple, easy to operate, printing, plate making simple and low cost, strong adaptability. Wide range of screen printing applications are common prints: color paintings, posters, business cards, binding covers, merchandising signs, and textile printing and dyeing.

The stencil printing is the simplest stencil printing, beginning in the late 19th century. This type of printing is made on a special type of wax paper, and a graphic version of the wax paper is made by a typewriter or a stylus, and an ink roller is used for printing on a wax paper plate. The desired printing effect can be obtained on the substrate. In stencil printing, the most widely used is screen printing screen printing is the silk fabric, synthetic fabric or metal mesh stretched on the net frame, using manual lacquer film or photochemical plate making method to make screen printing plate. In modern screen printing technology, screen printing plates are produced by photolithography using photosensitive materials (such that the screen holes in the graphic portion of the screen plate are through holes, and the screen holes in the graphic portion are not blocked. Live) oil paintings, prints, posters, business cards, binding covers, commodity packaging, product labels, textile printing and dyeing, glass and metal and other flat carriers.

In the electronics industry, screen printing technology has a 90% share. For example, the production of a TV set requires a lot of screen printing technologies, such as switches, operation panels, display screens, image anti-corrosion, and printed circuit boards. It can be said that there is no TV without screen printing, no electrical products, and it can be said that without screen printing technology, aviation, navigation, and aerospace industries will not develop. The ultra-large and ultra-thin wall-mounted TVs that represent future trends must also be screen printed. This shows that the importance of screen printing is extraordinary.

Screen printing ICs, abbreviated as ICs, are circuits that are very small and very light. The so-called degree of integration refers to how many transistors can be made on a chip of a certain size. Now that 16 megabits and 64 megabits have been solved, IOO megabits will soon be commercialized. In recent years, countries such as the United States, Japan, and Britain have been developing computers in the sixth generation of computers. They will have the same functions as human brains to think, analyze, judge, and blur information processing. Thick and thin ICs used in such computers are manufactured using screen printing thick film technology. The conductors, electrodes, dielectrics, resistors, resistors, etc. are all made using a screen printing process. We can say that screen printing technology is not only a high-tech content technology, but also screen printing products directly serve high technology.
