    摘要: Aqueous flux preparations with increased dynamic viscosity are provided. In the flux preparations, irreversibly dehydrated K2AlF5 (also denoted as orthorhombic K2AlF5 or phase II salt) provides for an increase of the dynamic viscosity if the aqueous flux preparations are aged, i.e., a contact between water comprised in the preparation and irreversibly dehydrated K2AlF5 is maintained for a certain time span, preferably for at least 12 minutes. The higher viscosity improves the brazing process, for example because less flux preparation drops off from the parts to be brazed.

    摘要: A solder is provided that produces a more impact resistant solder joint that is usable in high-end applications. The solder joint has a strong interconnection that can perform all of the normal functions of a solder joint while being more impact resistant. Furthermore, the solder joint retains its capabilities over the service life of a high-end product such as a computer or a cell phone. The solder meets the requirements of the soldering industry both today and into the future, including but not limited to an ability to be printed or dispensed with standard methods and conformity to health and safety standards.

    摘要: [Problems] Addition of an organic acid such as a dicarboxylic acid to a soldering flux in order to improve wettability causes a reaction with copper oxide to form a metallic soap of copper having a green color. Although this metallic soap of copper is not corrosive and does not decrease reliability, its external appearance is impossible to distinguish it from verdigris which is indicative of corrosion. There is need for a soldering flux which does not form a metallic soap of copper.[Means for Solving the Problems] Addition of a tetrazole or a tetrazole derivative to a soldering flux can prevent carboxyl groups from reacting exclusively with copper ions, thereby suppressing the formation of a metallic soap of copper having a green color. Among tetrazoles and tetrazole derivatives, 5-phenyl-1H-tetrazole and its derivatives which have hydrogen as a substituent in the 1-position and a phenyl, group which strongly attracts electron in the 5-position are effective at improving soldering since they result in an increased polarity in the solvent.
