Pcb Industry, A Major New Technology Is Gushing Out?? All Printed Electronic Technology

Fort York, Germany University of Applied Sciences, Professor W. Jillek electronic plating academic exchange in Shanghai at the annual meeting was entitled "Structure of electronic components function inkjet printer?? Ink-jetPrinting of Functional Structures for ElectronicDevices" report, the subheading is the "Print Printed Circuit Board?? Print the PrintedCircuitBoard". Report a more systematic introduction to the ink-jet printing in PCB manufacturing application of basic principles and relevant results.

PCB industry to change the current use of Subtractive as caused by high material consumption, high waste volume and other chronic disease, the whole addition method is the industry's long-awaited technology, today from the ink-jet printing of printed circuit board technology The emergence of the dream could become reality.

Routine application of HASL PCB manufacturing process technology, are generally a lot of procedure, the use of inkjet printing technology only six or so processes: CAD layout?? Bored?? Pre-treatment?? Inkjet printing?? curing. In addition to the short process, there are the following main advantages: no mask, very flexible, almost no waste, fine lines, suitable for rigid boards and flexible substrate, can be used to the production volume can be highly automated, multi-nozzle parallel actions can be achieve high capacity, can be used for three-dimensional package, enabling features such as active and passive parts of the integration. At the same time as the low melting point metal nano-materials, curing temperature of metal lines is expected as low as 200 -300 . The report mentioned solder resist ink-jet printing example, the machines used in 15 of 256 nozzle print head and print one (457mm × 610mm) size of the solder resist <60 seconds. Now desktop printer ink fluid volume has reached 1 / 10 skin liter frequency up to 40,000 times / second print speed? 35 pages / min, this machine price has fallen, all of which make it possible to print the printed circuit. As the ink-jet printing can be a variety of inorganic and organic materials, structural materials, therefore a variety of electronic functions can be integrated in the circuit board into print. In addition to other electrodes can also print making transistors, inductors, capacitors, resistors, batteries and other functional components. Making printed electronic circuits can be developed into a fully electronic processing of printing process, and a new processing technology. Can be used for display, signal board, sensors, photovoltaic cells and so on. Precisely because of the superiority of this new technology and the increasingly close to the background of industrialization, organized by the International Exchange IDTechEX company will continue, in September 2007 held recently in Tokyo, Japan, Asia PrintedElectronics Conference. 12-15 November 2007 in California has held exhibitions PrintedElectronics Masters Forum, information coming from the conference shows that many large international companies involved in this field, Japan's Mitsubishi, Sony, Germany's BASF Samsung have a lot of research in this area and report the results show. Although the registration fee up to more than 3000 U.S. dollars, but the participants reached the hundreds. April 2008 8-9, in turn, held in Dresden, Germany European PrintedElectrincs exchange. Because this is a handy, and can include printed circuit manufacturing technology major breakthrough in technology, providing a very attractive prospect, multinational companies will flock here, a vast reservoir of business opportunities.

All printed electronics as provide a very cheap, flexible, disposable electronic circuit potential of this technology can not only improve some of the traditional industries, such as the level of PCB production technology industry, but also may open up a vast new applications and new markets. Foreign firms have been in the electronic tag, OLED and other optoelectronic devices have made applications such as printing technology to produce debut with a removable color display | display device has been successfully used for 15 000 Valentine's cards, which display the price per square meter expected to be down 3 cents. IDTechEx has released the information, said the 2016 all-printed electronics, RFID in the world market will reach 10 billion U.S. dollars. CarylHolland estimates, the next 20 years, the market value of all printed electronics will reach 300 billion U.S. dollars.

Printed Electronics or PrintableElectronics term appears only a few years, some experts have proposed to use printed electronics to describe all the new technology.

Course, inkjet printing technology is not only technology, but also the traditional screen printing and other printing. In fact, PrintedElectronics with the IT industry is closely related to many branches and cross, such as OrganicElectronics, Thin Film Electronics, PlasticsElectronics. To make this technology faster and more widely used, particularly in the PCB industry are widely used, but also conductive ink in the non-noble metal nano-devices, high precision ink-jet printing equipment and other aspects of a lot of work. We understand that our country only a few universities, such as Fudan University, a professor engaged in production of conductive ink-jet printing of graphic and chemical battery, but also did not cause government leaders and business leaders adequate attention. PrintedElectronics no longer exhibits the laboratory, but soon gushing out of a red. China's leading expert Professor Yao Shouren PCB senior engineer called back in early 2007, i.e. to carry out this research work (printed circuit information, 2007,2).

China Printed Circuit Association (CPCA) has begun to integrate the leadership of universities, research institutes, enterprises set up all the power of printed electronics (PrintedElectronics) Chapter, the Secretary-General Wang Longji early December 2007 and 10 in person at Fudan University, Professor Yu Wei , director and other staff to discuss the preparatory work, hope in the near future the project will have a substantial push.
