摘要:
A process is intended to allow simple and particularly reliable electrolyte generation and conditioning from metal-containing used electrolytes and/or used process solutions and/or pulverulent metal wastes. For this purpose, waste products containing metal ions from metal surface treatment processes are to be treated by producing and/or using a metal ion mixed solution, replacing anions contained in the metal ion mixed solution with anions selected for an intended use selected and selectively removing metal ions which are categorized as unsuitable for the intended use selected from the metal ion mixed solution prepared in this way.

A method and coating material for applying electrically conductive printed patterns to insulating substrates is provided. The coating material includes a non-metallic, grainy carrier substance having metal of the oxidation degree 0 applied thereto. An energy radiation source, particularly of a deflectable laser beam, is used to secure anchoring of the carrier substance to the substrate in the region of the desired printed pattern. As a consequence of a three-dimensional arrangement of the metal, a three-dimensional nuclei distribution is produced that leads to a reliable and fast metallization of the printed pattern on the basis of chemical metal deposition. The method of the invention is especially suited for laser pattern transfer for the manufacture of printed circuit boards.

The invention concerns a method for the automatic analysis and determination of the amount or concentration of a specific component of a fluid in a metal-depositing bath, particularly a gold bath, wherein the fluid has several components. A quantity of bath fluid is taken from the bath in a first step. This quantity of fluid is diluted in a second step, in a third step a reaction agent and a solvent are added to a measured fractional amount of the quantity of diluted fluid during constant stirring, and, in a final step, a quantity of solvent-reaction agent mixture is conveyed to a measuring cuvette of a colorimeter and the concentration of the specific bath component is determined by means of colorimetric measurement. In addition, the invention concerns an apparatus for performing the above described method.

The invention relates to a method for producing a textured metal strip. In order to be able to implement a method of this type in a comparatively simple manner and thus cost-effectively, a metal layer (4) is galvanically produced on a textured substrate (1) having electrical conductivity, and the metal layer (4), while producing the textured strip (4a), is removed from the substrate (1).

Disclosed are a method and a device for filling material separations on the surface. In methods known in prior art, which are used for filling material separations, the substrate is often influenced in a negative manner by high processing temperatures and dissimilar additives. The inventive method overcomes said disadvantage, taking place at low temperatures and allowing the material separation to be completely filled without using dissimilar substances.

A process is intended to allow simple and particularly reliable electrolyte generation and conditioning from metal-containing used electrolytes and/or used process solutions and/or pulverulent metal wastes. For this purpose, waste products (a, b) containing metal ions from metal surface treatment processes are to be treated by producing and/or using a metal ion mixed solution (m), replacing anions contained in the metal ion mixed solution (m) with anions selected for an intended use selected and selectively removing metal ions which are categorized as unsuitable for the intended use selected from the metal ion mixed solution (v) prepared in this way.

The invention relates to an electrolysis bath for electrodepositing silver-tin alloys that, in addition to water serving as a solvent with a pH value of less than 1.5, contains a water-soluble silver compound, a water-soluble tin compound and an organic complexing agent. In order to obtain a stable electrolysis bath that enables the homogenous deposition of a compact tin-silver alloy with any type of composition, an aliphatic complexing agent having a sulfide group and an amino group is used as a complexing agent, whereby the functional groups are bound to different carbon atoms.
