Abstract

The invention provides a rapid determination method for a copper foil electroplating solution, in surface anti-oxidation treatment of copper foil production, zinc, nickel, potassium pyrophosphate and other substances are frequently used in the electroplating solution, and the stability of the content of the substances directly determines the appearance color, the impurity content and the oxidation resistance of the copper foil, so that in the production process, the content of impurities in the copper foil is greatly reduced. How to rapidly and accurately detect the content of the substance becomes a key point of quality assurance, and the method can be used for rapidly determining zinc, nickel and potassium pyrophosphate in the copper foil surface treatment electroplating liquid; compared with an artificial titration or spectrophotometric method for testing zinc-nickel potassium pyrophosphate in the electroplating solution, the method has the advantages of high detection efficiency, no detection waste liquid and the like; according to the analysis, the content of zinc, nickel and potassium pyrophosphate in the copper foil electroplating solution is determined by using the X-fluorescence spectrometry, the test result is accurate, the deviation is small, the solution detection requirement can be completely met, and the determination method of a titration method and a spectrophotometric method can be replaced.

Description

technical field [0001] The invention relates to the technical field of copper foil electroplating, in particular to a rapid determination method for copper foil electroplating solution. Background technique [0002] In the heat resistance treatment process of the copper foil surface, the method of electroplating other metals is generally used, and a layer of multi-element metals (such as zinc and nickel) is plated on the surface of the copper foil to form a multi-element alloy at high temperature to improve the heat resistance of the copper foil. . In addition, these coatings can not only block the attack of amines in the prepreg resin on the copper foil, but also help to improve the chemical affinity between the copper foil and the substrate, thereby improving the bonding force between the copper foil and the substrate; while the coke in the electroplating solution Potassium phosphate plays a complex role, which helps to improve the dispersion and coverage of the plating s...
