Abstract
The invention relates to a process method for electroplating copper on the surface of a minuteness aluminum wire. The process method comprises the following steps of: putting the minuteness aluminum wire which is processed at the front stage into nickel preplating solution, and plating at the temperature of 65 DEG C for 5min by using current at the density of 1A.dm<-2>, wherein the nickel preplating solution is prepared by the following raw materials in part by weight: 100 to 150 parts of NiSO4.6H2O, 20 to 40 parts of NiCl2.6H2O, 120 to 160 parts of Na3C6H5O7.2H2O, 20 to 50 parts of (NH4)2SO4, 10 to 50 parts of sodium gluconate, 0.5 to 1.5 parts of saccharin and 0.02 to 0.08 part of sodium lauryl sulfate; and mixing the solution and water according to weight parts, and adjusting the pH value to be 7.0. By the method, the surface of the aluminum wire which is subjected to nickel preplating and then is subjected to a copper plating process has a smooth and compact surface, fine and tightly-arranged grains and uniform and consistent colors and luster.
Description
Technical field
The present invention relates to the process method of the preceding nickel preplating of a kind of fine aluminium wire copper coating, the nickel preplating technology before the electro-coppering is carried out on the surface that is used for that fine aluminium wire is disposed in earlier stage.
Background technology
Along with developing rapidly of electronic information technology, metal wire material in the application of aspects such as various precision instruments, miniature automatically controlled instrument, wireless, electronics more and more widely.Aluminium has a wide range of applications in microelectronics as the conductivity good metal, but aluminium have the surface very easily oxidation and sull again extremely difficulty shortcoming such as remove, cause contact resistance big, can not weld with scolding tin, thereby had a strong impact on the performance of aluminium wire.The copper facing aluminium wire promptly has the high-frequency transmission performance of copper, have the advantage such as lightweight, softness of aluminium again, and conductivity is better than aluminium, and bending property is better than pure copper wire.So the instead of pure copper cash is made the best materials of high frequency cable and mobile communication cable inner wire during copper-clad aluminum conductor.Before trickle aluminium wire copper facing, only carry out pre-treatment, and do not carry out nickel preplating, the copper plate surface has blackspot and has plating leakage copper phenomenon so, has a strong impact on the copper facing quality.
Summary of the invention
The technical problem that the present invention will solve provides the process method of the preceding nickel preplating of a kind of fine aluminium wire copper coating; Adopt this method to carry out carrying out again behind the nickel preplating aluminium wire surfacing, the densification of copper-plating technique; Crystal grain is careful; Arrange closely, and the color and luster uniformity, originally the defective on the aluminium wire is also repaired.
For overcoming the above problems, concrete technical scheme of the present invention is following: the process method of a kind of fine aluminium wire surface electrical copper facing, the fine aluminium wire that dispose early stage to be put in the pre-nickel plating solution, and the employing current density is 1Adm
