Abstract
The invention provides tin plating liquid with a rear earth additive. The rear earth additive, which is 0.2-0.3% of tin plating liquid in mass, is added in the tin plating liquid, and the rear earth additive comprises LaCl3, Y2O3 or CeO2. According to the technical effects provided by the invention, a proper amount of the rear earth additive is added, so that the higher current efficiency achieves a lower temperature, the micro-fractures is retained to form, and the corrosion resistance of the plated layer is improved. Meanwhile, the free increment amount of rear earth and lots of non-metal elements have larger negative values, so that the corresponding chemical affinities are strong. By adding rear earth ions in the plating liquid, the properties of the plating liquid in the traditional electroplating process can be effectively improved due to the activity of the rear earth elements.
Description
Technical field
The present invention relates to a kind of tin plating electrolyte, relate in particular to a kind of tin plating electrolyte that contains rare earth addition.
Background technology
At present, copper facing exists several bigger shortcomings: porosity is big, very easily variable color in air, influences the corrosion resisting property of overall product coating.In order to overcome these shortcomings, often adopt the way thicken coating, so not only time-consuming but also take material, particularly on the Copper Foil plating automatic line, because the processing sequence designs fix, often before the entering next process, coating generation variable color influences the quality of coating.Add rare earth addition and carry out bright tin plating, can reduce the porosity of coating, anti-tarnishing ability and the solidity to corrosion, the particularly raising to the overall resistance to corrosion of coating that improve coating have fairly obvious effect.
Summary of the invention
The object of the present invention is to provide a kind of tin plating electrolyte that contains rare earth addition; Because REE has unique atomic structure that the 4f layer do not fill up and less electronegativity character; The free braised increment of rare earth and many non-metallic elements is big negative value simultaneously; Make its corresponding chemical affinity strong,, can improve the performance of plating bath in the traditional electrical depositing process effectively by the active characteristic of REE through in plating bath, adding rare earth ion.
The present invention realizes like this, adds the rare earth addition that accounts for tin plating electrolyte quality 0.2-0.3% in the tin plating electrolyte, and rare earth addition has LaCl

Technique effect of the present invention is: adding rare earth addition in right amount can obtain higher current efficiency under the lower again temperature; Suppress the formation of tiny crack; The coating erosion resistance improves, and the free braised increment of rare earth and many non-metallic elements is big negative value simultaneously, makes its corresponding chemical affinity strong; Through in plating bath, adding rare earth ion, can improve the performance of plating bath in the traditional electrical depositing process effectively by the active characteristic of REE.
