PCB screen printing

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 outstanding characteristics is the integration of screen printing technology and electronic information technology, its products have the distinctive characteristics of screen printing technology and electronic information technology at the same time, because it has dual characteristics, so the electronic screen printing technology products have high technology content and high value-added return. In short, electronic screen printing technology refers to the combination of electronic information technology and screen printing technology formed a new modern screen printing technology with the characteristics of electronic information technology.

Electronic screen printing products are like a variety of flowers, I believe the following electronic screen printing products examples will be eye-opening to readers.

(1) Screen printing/wet film technology

Wet film (optical imaging corrosion resistant plating ink coating) technology is a variety of high-precision high-density double-sided or multilayer printed circuit plate (PrintedCircuitBoard, printed circuit board, referred to as: Surfacemount Technology and smt (short for surface assembly technology or surface mount Technology). PCBS are the preferred image-generating technology in flexible PCB manufacturing. Wet-film techniques produce fine lines up to 0.08mm or more.

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

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

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

(5) It is suitable for conductive adhesive or conductive paste/screen printing technology in the manufacturing technology of laminated multilayer plate in super high performance electronic products.

(6) Screen printing embedded resistance manufacturing technology in multi-layer PCB manufacturing technology.

(7) High precision screen printing technology of tin paste/template in smt technology and high precision screen printing technology of BallGrioArray (ball grid array packaging technology) in BGA repair in smt technology.

(8) Screen printing technology in grating plate (disk) or grid, code plate and other manufacturing technologies, in the production of the above products, the production unit has easily obtained neat and symmetrical fine lines and fine spacing of 0.012mm wide, and has formed mass production capacity.

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

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

(11) LCD CrystalDisplay/screen printing technology.

① Computer LCD monitor.

Screen printing technology in the manufacturing technology of mobile phone, business communication, electronic dictionary and various electronic instruments

(12) Screen printing technology in solar cell manufacturing.

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

(14) Screen printing technology in the manufacturing technology of disposable mobile phones.

The magic of electronic screen printing technology also lies in the application range and service object of the product, just take PCB and film switch as an example, in the large-scale parallel computer system, in the mangle train, in the nuclear submarine "Long March 1", in the ballistic missile nuclear submarine underwater launch carrier rocket; In underwater robots and new guided-missile destroyers, the use of human-designed, manufactured PCB film switches is proving. Active in the field of high - tech electronic screen printing technology and its products have a strong strength and good prospects.

All the powerful companies and groups in the world are concerned about electronic information technology and its industry. Such as microelectronic aspects of super memory, superconducting components, super intelligent chips, self-proliferating chips, electronics field of terabit optical file, terabit optical communication components, optical computer components. The progress of biosensors, bio computers, super-parallel computers, artificial simulation systems and self-multiplying database systems required by information systems and equipment in bio electronics will affect the economic and even political nerves of governments and groups. When the electronic screen printing technology and its products are in contact with the economic and even political nerves of various governments, there is no reason to doubt the bright future of electronic screen printing technology.

If we concertize the above conclusion that the prospect of electronic screen printing technology is very good from the level of economic development trend, and specifically compared and predicted the production capacity and output value of electronic information products in recent years, we can also get strong evidence that the prospect of electric screen printing technology is very good. It is predicted that in 2005, my LCD annual output can reach 2 million square meters, from the perspective of development, the future of the display LCD is an inevitable trend. Moreover, the application of EL display is becoming more and more widespread. It should be said that all the electronic devices that need to display will be LCD or EL. These will be huge markets for electronic screen printing technology.

The computer industry has proposed to "enter the new era of liquid crystal computer" (by the end of 2000, the global PC users have more than 500 million). The LCD in the computer, the PCB in the computer and the computer keyboard circuit are inseparable from the electronic screen printing technology. In the process of the computer market this "cake" is growing, we also see the bright prospect of electronic screen printing technology.

The application range of EL technology is very wide, such as in the field of signs, badges; In the field of backlight, it is mainly used for backlight and LCD back lighting of various LCD modules. In the field of billboard application. EL display technology and its large commercial market is clearly a strong "stimulus" for us screen printing practitioners.
