In fort of German new York technology university Professor W.Jillek eletroplates in Shanghai electron the problem was made be on academic communication annual meeting " the ink jet of structure of electronic component function is printed -- Ink-jetPrintingofFunctionalStructuresforElectronicDevices " report, its subhead is " the printed circuit that print board -- PrintthePrintedCircuitBoard " . In the report relatively introduced to print the rationale that creates medium applying in PCB and relevant achievement about ink jet systematically.

The tall material that PCB industry wants a change to because use subtractive process place,be caused currently is used up, the chronic and stubborn disease such as quantity of tall waste liquid, complete addition law is industry expects long already technology, print printed circuit from ink jet today board technical occurrence, the dream becomes reality likely.

The PCB that convention application sirocco makes smooth technology produces a process to want a lot of process commonly, and use ink jet to print a technology to require 6 or so process only: CAD cloth pursues -- bore -- pre-treatment -- ink jet is printed -- solidify. Besides working procedure weak point, still have the following and main good point: Need not very model of attack by surprise, agile, do not have 3 useless, line almost careful, applicably at just sexual board and flexibility matrix, usable coil to produce means, high automation, can much shower nozzle collateral movement can obtain Gao Sheng. At the same time the low melting point as a result of material of metallic accept rice, make hopeful of temperature of metallic line solidify low to 200 ℃ - 300 ℃ . The case that ink jet of block welding flux prints is mentioned in the report, used machine has 15 heads that print and 256 spray head, print (457mm × 610mm) the ＜ of block welding flux of the area 60 seconds. Chinese ink liquid accumulates table printer to already achieved 1/10 Pi Sheng nowadays, frequency can be amounted to 40000 times / second, 35 pages of ﹥ of the speed that print / cent, this machine price already fell considerably, these all making that the printed circuit that print becomes a possibility. As a result of can ink jet prints all sorts of inorganic, organic material, because material of all sorts of this electronic function construction can be passed,print compositive at circuit board in. Still can print the transistor that make, inductance, capacitance, resistor, function component such as batteries besides electrode. Make print electronic circuit to be able to develop thereby become a kind to print an electron to machine a process completely, a kind of brand-new treatment craft. Can use at the respect such as monitor, signal board, sensor, photocell. Because the advantage of this kind of new technology is mixed,be close to the setting of industrialization increasingly, the international communication that holds by IDTechEX company will be constant, just held Asian PrintedElectronicsConference in Japanese Tokyo in September 2007. 12-15 day held communication of forum of PrintedElectronics Great Master to reveal again in American California in November 2007 meeting, from can upload the information that come to see, all much big companies on international all sortie this domain, samSung of the BASF of 3 water chestnut of Japan, Suo Ni, Germany, Korea has a lot of research to achievement is revealed and report in this respect. Although register cost to be as high as 3000 much dollars, but the ginseng person that meet all amounts to hundreds person. 8-9 day will be in Germany again in April 2008 heart is tired this hold European PrintedElectrincs communication to meet suddenly. Because this is a kind of tentacle,can reach, the engineering technology that can make include printed circuit to make a technology produce major breakthrough, offerred very inviting application prospect, international transnational corporation just can come in great numbers, contain is worn here huge business chance.
