Definitions

  • centrifugal pumps leads to disadvantages, above all in the case of the abrasion of the pump housing and the blades of the impellers as a result of cavitation caused by turbulence, which can result in irregularities in the liquid transportation and bathing of heating devices and substrates, but also in an impairment of the properties of the liquids themselves due to turbulence and cavitation .
  • propeller devices or propeller-like devices which, according to the invention, are also called mixing blades or mixing propellers, and which are arranged in tanks and/or coating modules of the coating units according to the invention, despite high rotational speeds turbulence can be largely avoided or a turbulence range set which allows a sufficient bathing of the substrates to be coated and the heating devices (also called heating elements or heating modules) as well as liquid exchange at the surfaces and throughflow of the holes, without on the other hand damaging the dispersions or emulsions by too-strong turbulence.
  • the disadvantage of axial-flow pumps, that they build up an inadequate flow, is surprisingly removed as a result of this, without damaging turbulence or cavitation being produced.
  • the size (diameter) of the mixing blades (mixing propellers), the number thereof per tank or module and their arrangement and direction of rotation are determined depending on the design of the tanks and modules (length, width, depth, total volume) .
  • This can prove to be very different for the different coating tasks, such as metallization, such as e.g. copper- plating, tin coating, deposition of silver, coating with metal oxides.
  • characteristic of all of these embodiments is the fact that waves that run irregularly form at the surface of the modules, i.e. of the coating baths in the modules, without forming large stable vortices. It is likewise characteristic that the wave patterns change, thus no standing waves form.
  • mixing blades can also be introduced from the side through the tank/module walls, wherein the respective feedthrough is then sealed off with suitable O-rings.
  • the propellers inside the tanks and/or coating modules without connecting them to a motor by means of axles, but to drive them without mechanical connection, e.g. by rotating magnets attached outside the coating modules or tanks, for which the internally rotating propeller then has a corresponding magnetic component, e.g. a bar magnet.
  • the power transmission thus takes place in this case e.g. via a field acting into the module or tank.
  • the unit according to the invention can be charged with coating material that comprises metals and/or metal oxides, in particular Fe, Sn, Cu and alloys and oxides thereof as well as compounds or mixtures with intrinsically conductive polymers, in particular polyaniline.
  • the coating material is present in particular in the form of a dispersion or emulsion.
  • the dispersion or emulsion generally has a viscosity in the range of from about 0.5 to 500 mPas, such as about 0.5 to 200, 300 or 400 mPas, in particular about 0.7 to about 100 mPas, such as about 0.7 or 1 to about 50, 60, 70, 80, 90 or 95 mPas, measured e.g. with a suitable cone-and-plate viscometer or with a suitable Ubbelohde viscosimeter , at room temperature, i.e. as a rule 20°C.
  • the solids content thereof is generally from about 0.1 to about 50 wt.-%, in particular about 0.2 to about 45 wt.-%, such as about 0.2 to about 40 wt.-%.
  • Aqueous liquids in particular water, are generally used as dispersants, optionally with a proportion of up to 15% of water-miscible organic substances which are preferably low- volatile.
  • the dispersions or emulsions have an average particle or droplet diameter in the range of from about 10 nm to about 1 pm, preferably from about 20 to about 500 nm, as can be determined by means of laser Doppler particle size measurement devices .

Abstract

La présente invention concerne une unité de revêtement chimique à écoulement à faible turbulence qui est caractérisée en ce qu'elle comprend au moins un module de revêtement pour appliquer au moins une matière de revêtement sur au moins un substrat, en particulier sur une carte à circuits imprimés. Au moins un module de revêtement a au moins un dispositif de propulsion qui déplace et transporte la matière de revêtement avec un écoulement à faible turbulence, avec pour conséquence qu'une immersion suffisante des substrats à revêtir et/ou d'éléments de chauffage éventuellement présents est obtenue. La présente invention concerne en outre un procédé de revêtement correspondant.
