Science-Technology Title: Tanaka Precious Metals Begins Providing World's First Silver Ink Able to Form Electronic Circuits with UV Light Enabling wiring through room-temperature hardening without heating, optimal for all base materials such as PET film Tokyo, Jan 17, 2012 - (JCN Newswire) - Tanaka Holdings Co., Ltd (a company of Tanaka Precious Metals) today announced that Tanaka Kikinzoku Kogyo K.K., which operates the Tanaka Precious Metals' manufacturing business, had commercialized the world's first conductive silver ink capable of forming electronic circuits using only hardening by ultraviolet (UV) light without the need for hardening by heating, and will begin selling the product on January 18. After printing a circuit on base material using this ink and exposing it to UV light for approximately 0.3 seconds, the user can instantly harden the printed film even at room temperature to form a circuit that carries current. At a film thickness of five micrometers or more (one micrometer is one millionth of a meter), it is possible to form wiring on the same level as the conductive material generally used at present, with electrical resistivity of 10- 3©cm (10-3© per 1 centimeter). By using this ink, it is possible to perform wiring not only on glass base material and substrates, but also flexible base material such as polyvinyl chloride film (PVC film) and polyester film (PET film) on which it was previously difficult to form electronic circuits due to their susceptibility to heat. In particular, because it is possible to form wiring on all types of film base material by attaching this silver ink using flexographic printing that transfers ink by making it adhere to protrusions on a rubber plate, this ink is very effective wiring material for printed electronics which produces electronic components by printing. It is expected to be applied to electronic circuits in a wide range of products including solar cells (silicon, dye sensitized, etc.) and organic EL (electroluminescence) lighting, in addition to touch panel displays, electronic books, RFID (radio-frequency identification) tags and electronic packaging for use in drug therapy monitoring. - Challenge in Thermal Hardening A variety of technologies are currently being developed to enable popularization of printed electronics on a practical level as a next generation technology able to produce electronic equipment that is thin, lightweight and difficult to break at a low cost. Wiring materials such as materials enabling current to be carried in a circuit by heating printed metal nanoparticles are being developed, but it is necessary to form circuits without heating in order to form circuits on all types of base material such as PET film susceptible to heat. Heating conditions for ink hardening have been an issue in wiring materials because they all required a heating process such as materials requiring heating at 50 degrees Celsius to 100 degrees Celsius for several minutes, and materials requiring heating to supplement hardening by UV irradiation. - World's First Commercial Product This conductive silver ink commercialized by Tanaka Kikinzoku Kogyo for the first time in the world is a wiring material able to instantly form electronic circuits simply by being irradiated with UV light under room temperature conditions without heating due to optimization of the composition and mixture of resin containing silver nanoparticles and reaction initiator. As there is no need for the large equipment or thermal processing time required in thermal hardening, it is possible to significantly improve production speed per unit of area using an overwhelmingly small device space. A total of three silver inks using different types of resin and reaction initiator will be available, and users can select the materials according to their manufacturing equipment and application. Tanaka Kikinzoku Kogyo will sell the product for some time as a sample for solar cell manufacturers, display manufacturers and printer manufacturers. The company will also work on technological improvements such as improving the electrical resistance of products while continuing to monitor trends in the industry aimed at the full-scale implementation of printed electronics expected to take place in the future. Exhibits of the Product and Sample Boards Tanaka Kikinzoku Kogyo has scheduled to display this silver ink at the 41st INTERNEPCON JAPAN, which is Asia's largest exhibition for electronics manufacturing and mounting technologies, held at Tokyo Big Sight (Koto-ku, Tokyo) over three days from January 18 (Wed) until January 20 (Fri). In addition to the display of a flexible board upon which an electronic circuit has been actually formed using the product, technical personnel will also be on-site at the display booth (West 6-12) to respond to interviews.

I won't even pretend to know exactly what advances this will allow. Although an obvious one is the holy grail of monitors, the FLEXIBLE monitor. Electronic newspapers/books/and/or "paper" anyone? Amazing. Spoiled, stupid and ignorant, brain dead phuckwads, libTURD fools, tools, and idiots, are the real sickness; the messiah "king" obammy and his regime are only the symptoms. #2. To: All (#0) . Just as I feared, this site just doesn't have enough people smart enough to even understand this story, let alone it's implications. I wonder what it is like to live in a world and have no fucking idea how anything actually works? I wonder what is it like to be dumber than your appliances? No wonder the CULT of personality and totally superficial BS dominate this so called "culture". Oh well ... stoooopid IS as stoooopid DOES. Spoiled, stupid and ignorant, brain dead phuckwads, libTURD fools, tools, and idiots, are the real sickness; the messiah "king" obammy and his regime are only the symptoms.
