Electricalty Conductive Formulations Filled NanoSize Silver Filler forInk-Jet Technology

Ascurrent studies andanalyses imply, thefuture of modemmicroelectronics solutions isutterly dependent on nanotechnology within whichnanosize materials are moreandmorefrequently produced andapplied. This results iptheunparalleled possibility ofcreating new,so farimpossible tomanufacture products aswellas application technologies. Consequently, this results ina significant increase inthepossibility ofminiaturization of elements of electronic systems by reducing the dimensions ofitselements themselves aswellas increasing thedensity oftheir compaction. Polymer composites containing silver particles of single nanometers (several atoms) maybeprinted with theapplication oftheInk-Jet method inorder toobtain a line or'points' being electricity conductors orcontacts in electronic assembly. TheInk-Jet printing method utilizes thepercussive effect ofa piezoelectric compressing capillary element within microsecond andthusresulting insudden 'expenditure' ofthedosed composition. During theverydosing process, thedosed portion isaffected by acceleration of105g,whichmaycauseseparation of elements ofvarious specific weights fromthedosed composition. Therefore, thephysically best composition hasthefeatures ofaspecific solution inwhich thefiller conducting electricity (silver) hasthedimensions insignificantly differing fromthedimensions ofthe binder inwhich itis'suspended'. One ofthecrucial technical problems isthe production ofsilver particles separated fromoneanother andofadequately small andrepetitive atdefined time dimensions. Thecomnmunication hasshowntheresults of theworks, which enabled silver powders of3-7nmona semi-technical scale. Intheprocess oftechnology optimization, experiment-planning method wasapplied. Detailed miicroscope examination ofthepowders, with theuseof,amongothers, theSTM microscope, was canried out,andcompositions inInk-Jet printing applications wereexamined, too. Theobtainment ofasilver nanosize filler ofrepetitive geometric parameters andtechnical characteristics allows further workson formulas ofelectricity conducting compositions depending onapplication requirements in theInk-Jet printing technology.
