Abstract:
Ti ink compositions for printing, such as ink jet printing, are disclosed. The ink compositions comprise a liquid dispersion of Ti hydride powder having a mean particle size of less than 10.0 microns; a liquid carrier; and at least one surfactant. Methods of making and using the disclosed inks are also disclosed. For example, a finished Ti product can be produced by printing the disclosed ink composition, such as by ink jet printing, to form a green article, heating the green article to dehydrogenate it and form a Ti containing part. The method may further comprise sintering the Ti containing part to produce a sintered Ti product. In an embodiment, the method comprises printing one or more support materials for the ink composition, that comprises solid particles of a metal oxide, a metal carbide, a metal nitride, a polymer, or combinations thereof.
Abstract:
Provided are a Ni ball, a Ni core ball, a solder joint, solder paste and foamed solder which are superior in the impact resistance to dropping and can inhibit any occurrence of a poor joints. An electronic component 60 is constructed by joining a solder bump 30 of a semiconductor chip 10 to an electrode 41 of a printed circuit board 40 with solder paste 12, 42. The solder bump 30 is formed by joining an electrode 11 of the semiconductor chip 10 to the solder ball 20. The 20 according to the present invention contains purity which is equal to or higher than 99.9% and equal to or lower than 99.995%, sphericity which is equal to or higher than 0.90, and Vickers hardness which is equal to or higher than 20 and equal to or less than 90HV.

Abstract:
The present invention discloses a nano-silver powder dispersible in environment friendly weak solvents, method for preparing the same and an electrically conductive ink comprising the nano-silver powder. The present invention employs a disperser dissoluble in water and weak solvents and an alcohol amine as reducing agent to prepare mono-dispersed nano-silver, and employs ultrafiltration for purification and spray drying process to obtain a nano-silver powder dispersible in weak solvents, and thereby obtain an eco-solvent nano-silver electrically conductive ink. The electrically conductive ink in accordance with the present application has advantages of high safety, low volatility, low toxicity, high flash point, resistant to ultraviolet radiation and moisture etc., and can be used with uncoated bearing substrates, and is suitable for use in outdoor environments.
