“…Similar physics, particularly when used to induce pulsating jets as opposed to steady cone jets, 4,5 can be exploited for printing liquid inks, with the possibility for resolution that extends into the submicron range, 6 orders of magnitude better than that available from commercial thermal or piezoelectric inkjet printers. 7,8 Figure 1 shows a schematic illustration of the nozzle and substrate in this electrohydrodynamic jet ͑e-jet͒ printing technique, 6 together with the simulated static electric field distribution and an example of printing of dots with ϳ1.5 m diameters. The robust operation of printers of this type, which use pulsating jets, requires delicate control of the jetting frequencies together with ultrafine ͑microns to fractions of a micron in inner diameter͒ nozzles.…”

This paper presents simple scaling laws that describe the intrinsic pulsation of a liquid jet that forms at the tips of fine nozzles under electrohydrodynamically induced flows. The jet diameter is proportional to the square root of the nozzle size and inversely proportional to the electric field strength. The fundamental pulsation frequency is proportional to the electric field strength raised to the power of 1.5. These scaling relationships are confirmed by experiments presented here and by data from the literature. The results are important for recently developed high-resolution ink jet printing techniques and other applications using electrohydrodynamics.

“…The latter is especially of great importance, as the number of passives fall for each active component rise, stimulating research and development effort in the field of new materials and technologies [1], like e.g. embedding passives into printed circuit boards [2], thick-film technologies that use both quite new materials and layer deposition methods, including various printing techniques [3,4], in order to improve resolution and to reduce dimensions of the components as well as to develop new functional devices [1].…”

Studies of electrical properties, including noise properties, of thick-film resistors prepared from various resistive and conductive materials on LTCC substrates have been described. Experiments have been carried out in the temperature range from 300 K up to 650 K using two methods, i.e. measuring (i) spectra of voltage fluctuations observed on the studied samples and (ii) the current noise index by a standard meter, both at constant temperature and during a temperature sweep with a slow rate. The 1/f noise component caused by resistance fluctuations occurred to be dominant in the entire range of temperature. The dependence of the noise intensity on temperature revealed that a temperature change from 300 K to 650 K causes a rise in magnitude of the noise intensity approximately one order of magnitude. Using the experimental data, the parameters describing noise properties of the used materials have been calculated and compared to the properties of other previously studied thick-film materials.

“…In the future, different printing methods are likely to co-exist in the printed electronics market. The choice of printed electronics technologies will base on the normal parameters such as run length, feature size and variable data requirements (Blayo & Pineaux, 2005;Parashkov, et al, 2005). Three requirements of printed electronics are resolution, accuracy of position, and amount of material deposited (i.e., thickness and content of active particles).…”

“…In printed electronics, silver particles are often used to form the conductive layer. Thin conducting layers are preferred to maintain low manufacturing costs while maintain good radiation efficiency (Parashkov, et al, 2005;Björninen, et al, 2009). Therefore, the amount of silver and the thickness of the conductive layer need to be well defined.…”
