Modern electronic information technology is a general term for sensing technology (information detection, transformation, display), computer technology, communication technology, and microelectronic technology. The rapid development of electronic information technology and its industry has not only enabled the automation of production, the production efficiency has increased hundreds of times, the cost has been greatly reduced, and the quality of products has been continuously improved. It has also opened up a new era in which machines replace human physical strength and even some mental work. . Electronic information technology has penetrated into various fields of the national economy, completely changing the traditional production methods. According to statistics, 65% of the world's gross national product is now related to integrated circuits.

The so-called "electronic screen printing technology" refers to the new technology produced by the combination of electronic information technology and screen printing technology with a long history. It is a special field in the screen printing industry. Its most prominent feature is the fusion of screen printing technology and electronic information technology. Its products have both the distinctive characteristics of screen printing technology and the distinctive characteristics of electronic information technology. Because of its dual characteristics, the products of electronic screen printing technology have high technological content and high value-added return. In short, electronic screen printing technology refers to a new modern screen printing technology with the characteristics of electronic information technology formed by the combination of electronic information technology and screen printing technology.

The products of electronic screen printing are like flowers and flowers. I believe the following examples of electronic screen printing products will open the eyes of readers.

(1) Screen printing / wet film technology

Wet film (photographic resist, anti-plating ink coating) technology is a variety of high-precision high-density double-sided or multilayer printed circuit boards (Printed Circuit Board, printed circuit board, PCB for short) and SMT (Surface Mount Technology, surface assembly technology Or short for surface mount technology), PCB is the first choice for image generation technology in flexible printed circuit board manufacturing technology. The fine lines produced by wet film technology can reach 0.08mm or even finer.

(2) Screen printing / solder resist ink and screen printing / marking symbol coating technology in PCB manufacturing technology.

(3) Screen printing / silver paste or carbon paste through hole in PCB manufacturing technology, PCB manufacturing technology.

(4) Screen printing / carbon film PCB manufacturing technology.

(5) Suitable for conductive adhesive or conductive paste / screen printing technology in the manufacturing technology of laminated multilayer boards in ultra-high performance electronic products.

(6) Screen printing embedded resistor manufacturing technology in multilayer PCB manufacturing technology.

(7) High-precision screen printing technology in tin paste / stencil high-precision screen printing technology in SMT technology and BGA (BallGrioArray, ball grid array packaging technology) in SMT technology.

(8) The screen printing technology in the manufacturing technology of grating plates (disks), grids, code disks, etc., when manufacturing the above products, existing production units can easily obtain neat, symmetrical fine lines and fine lines of 0.012mm width Distance, and has formed a mass production capacity.

(9) Screen printing technology of large-scale integrated circuit frame and screen printing technology of thick film integrated circuit.

(10) Screen printing technology in touch screen manufacturing technology.

(11) Liquid crystal (Liguid Crystal Display, referred to as LCD) / screen printing technology.

â‘ Computer LCD monitor.

â‘¡ Screen printing technology in mobile phone, business communication, electronic dictionary and various electronic equipment manufacturing technologies

(12) Screen printing technology in solar cell manufacturing.

(13) Screen printing technology in PTC main heating element manufacturing technology.

(14) Screen printing technology in disposable mobile phone manufacturing technology.

The magic of electronic screen printing technology also lies in the application range and service objects of the product. Taking PCB and membrane switches as examples only, in the massive parallel computer system, on the magnetic levitation train, on the nuclear submarine "Long March 1", in the ballistic The missile nuclear submarine launches the launch vehicle underwater; on underwater robots and new missile destroyers, the application of PCB membrane switches designed and manufactured by the Chinese themselves proves to the world; the electronic screen printing technology and its active in high-tech fields The product has strong strength and beautiful prospects.

Powerful countries and groups in the world are all concerned about electronic information technology and its industry. Such as microelectronics super memory, superconducting elements, super intelligent chips, self-proliferating chips, terabit optical files in the field of optoelectronics, terabit optical communication components, optical computer components. Biosensors, biosensors, biocomputers, ultra-parallel computers, artificial simulation systems, and self-proliferating database systems required by information systems and equipment. Any progress in any aspect will affect the economic and even political nerves of governments and groups in various countries. . When electronic screen printing technology and its products are hooked to the economic or even political nerves of governments of various countries, what reason do we have to doubt the good prospects of electronic screen printing technology ?!

If we materialize the conclusion that the prospect of the electronic screen printing technology obtained from the perspective of economic development trend is very good, specifically to the comparison and prediction of the capacity and output value of electronic information products in recent years, we can also get the electric wire Strong evidence that the prospect of screen printing technology is very good. It is predicted that China's LCD annual output will reach 2 million square meters in 2005. From the perspective of development, the future LCD display is an inevitable trend. Moreover, the application of EL display is getting wider and wider, it should be said that all electronic devices that need to be displayed will be LCD or EL. These will be huge markets for electronic screen printing technology.

The computer industry has proposed "to enter a new era of LCD computers" (by the end of 2000, there have been more than 500 million personal computer users worldwide), the LCD in the computer, the PCB in the computer and the computer keyboard circuit are all inseparable from electronic screen printing Technically, in the process of making this "cake" bigger and bigger in the computer market, we have also seen the bright future of electronic screen printing technology.

The application range of EL technology is very wide, such as the application in the field of signs and badges; in the field of backlight, it is mainly used for the backlight of various liquid crystal modules, LCD backlighting; and the application in the field of billboards. EL display technology and its huge commercial market are obviously a powerful "stimulus" for our screen printing practitioners. In summary, isn't an electronic screen printing technology with a splendid future protruding into our eyes alive?
