PCB industry, a major new technology gushing out-PCB-electronics industry – chin
Fort York, Germany University of Applied Sciences, Professor W. Jillek electronic plating academic exchanges in Shanghai at the annual meeting was entitled " Electronic component Functional structure of the ink-jet printing?? Ink-jetPrintingofFunctionalStructuresforElectronicDevices "report, its subtitle is" print print Board ?? PrintthePrintedCircuitBoard ". Report of the more systematic introduction to the inkjet print PCB The Manufacturing 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 productivity, 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 and 256 nozzle print head, print one (457mm × 610mm) size of the solder resist <60 seconds. Now desktop printer ink fluid volume has reached 1 / 10 skin up, frequency up to 40,000 times / second print speed? 35 pages / min, the 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 production Transistor , Inductors, Capacitance , Resistance, Battery 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, Sensor , Light battery 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 IDTechEX company will continue, in September 2007 held recently in Tokyo, Japan, Asia PrintedElectronicsConference. 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. It is precisely 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, the 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, O LED 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 card, which displays the price per square meter is expected to drop 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.
PrintedElectronics or PrintableElectronics term appears only a few years, some experts have proposed to use printed electronics to describe all the new technology.
