Definitions
- the invention relates to an acid bath for the galvanic deposition of shiny, ductile and leveled copper coatings and the use of this combination.
- the bath according to the invention can be used both to reinforce the conductor tracks of printed circuits and in the decorative sector.
- the prior art includes baths which contain a mixture of oxygen-containing high-molecular compounds with organic, in particular aromatic thio compounds (DE-AS 1521062).
- DE-AS 1521062 organic, in particular aromatic thio compounds
- DE-AS 2039831 describes an acidic copper bath which, in addition to a polymeric oxygen-containing compound and a thio compound with a water-soluble group, also contains at least one dye from the series of the polymeric phenazonium compound in solution. Further work describes the combination of organic thio compounds and polymeric oxygen-containing compounds with other dyes such as crystal violet (EP-PS 71512) or phthalocyanine derivatives with aposafranine (DE-PS 3420999) or a combination with amides (DE-PS 2746938).
- the object of this invention is to avoid these disadvantages.
- R 1 is a lower alkyl C- j to C_ j .
- R 2 is an aliphatic chain or an aromatic radical and a either means 1 or 2.
- the amount in which the polyalkylene glycol dialkyl ether can be added in order to achieve a significant improvement in the copper deposition is about 0.005 to 30 g / liter; preferably 0.02 to 8.0 g / liter.
- the real molar mass can be between 500 and 35000 g / mol; preferably 800 to 4000 g / mol.
- polyaclylene glycol dialkyl ethers are known per se or can be prepared by processes known per se by reacting polyalkylene glycols with an alkylating agent, such as, for example, dimethyl sulfate or tert. Bute " .
- Table 1 shows examples of the polyalkylene glycol dialkyl ethers to be used according to the invention and their preferred uses. Turning concentration listed: Table 1
- At least one thio compound with a water-solubilizing group can be added to the compound according to the invention.
- Further additives, such as nitrogen-containing thio compounds, polymeric nitrogen compounds and / or polymeric phenazonium compounds, can also be added to the bath.
- Table 2 lists some common thio compounds with water-soluble groups and their preferred application concentration:
- Table 3 contains examples of nitrogen-containing thio compounds (so-called thiourea derivatives) and Table 4 for polymeric phenazonium compounds and Table 5 for polymeric nitrogen compounds.
- N-acetylthiourea N-trifluoroacetythiourea N-ethylthiourea N-cyanoacetylthiourea N-allylthiourea o-tolylthiourea N, N'-butylene thiourea thiazolidinethiol (2) 4-thiazolinethiol (2)
- Imidazolidinthiol (2) (N, • -ethylenethiourea) 4-methyl-2-pyrimidinthiol 2-thiouracil 1 Tables 3 to 5 may possibly be omitted.
- composition of the bath according to the invention can vary within wide limits.
- an aqueous solution of the following composition is used:
- Copper sulfate (CuS0 4 * 5H 2 0) preferably
- chloride ions Preferably chloride ions
- copper sulfate instead of copper sulfate, other copper salts can also be used, at least in part.
- the sulfuric acid can also be partially or completely replaced by fluoroboric acid, methanesulfonic acid or other acids.
- the chloride ions are added as alkali chloride (eg sodium chloride) or in the form of hydrochloric acid pa.
- alkali chloride eg sodium chloride
- hydrochloric acid pa The addition of sodium chloride can be omitted in whole or in part if halogen ions are already present in the additives.
- customary brighteners, levelers or wetting agents can also be present in the bathroom.
- the working conditions of the bath are as follows:
- the electrolyte movement takes place by blowing clean air in, so strongly that the electrolyte surface is in a strong flush.
- Copper with a content of 0.02 to 0.067% phosphorus is used as the anode.
- a well-leveled, shiny copper coating is obtained at an electrolyte temperature of 30 ° C. with a current density of 4 A / dm 2 and movement by blowing in air.
- the electrolyte is now subjected to a permanent load of 500 Ah / 1, the gloss former consumed during the electrolysis being supplemented to set values, the electrolyte at the tub edge shows clear gelatinous polymer framing.
- the electrolyte is now subjected to a permanent load of 500 Ah / 1, the gloss former consumed during the electrolysis being supplemented to set values, the electrolyte at the tub edge shows clear gelatinous polymer framing.
- the compound according to the invention polypropylene glycol dimethyl ether
- the electrolyte shows no polymer framing after aging.
- the electrolyte is now subjected to a permanent load of 500 Ah / 1, the gloss former consumed during the electrolysis being supplemented to set values, the electrolyte at the tub edge shows clear gelatinous polymer framing.
- the compound according to the invention octyl monomethyl polyalkyl glycol, is added to the electrolyte in the same amount, the electrolyte shows no polymer framing after aging.
