Metallized magnetic core and ceramic core for driving nickel ion adsorption by adopting conduction assisting medium

Abstract

The invention provides a metallized magnetic core and a ceramic core for driving nickel ion adsorption by adopting a conduction assisting medium. The metallized magnetic core and the ceramic core are characterized in that a sintered workpiece with a conductive electrode is selected; the workpiece is cleaned before plating; the chemical nickel liquid medicine is mixed with purified water in proportion, after heating in a vessel, the workpiece and the conduction assisting medium are poured into a screen, and nickel ions in the liquid medicine are driven by the conduction assisting medium to be adsorbed on the surface of the electrode to form a nickel layer; the workpiece is separated from the medium through screening; the workpiece is poured into the screen again and put into the original plating solution for continuous chemical nickel plating; and after nickel plating, the workpiece is taken out, cleaned and loaded into an electroplating roller, a proper proportion of conduction assisting medium is added, the electroplating roller is put into an electroplating bath, and electroplating operation is completed. According to the scheme, the process is saved, the use of raw materials is reduced, so that manpower and material resources are greatly reduced, resource saving and environment friendliness can be realized, and unique value is created for the development of the world electronic industry.

Description

technical field [0001] The invention relates to the technical field of inductance, in particular to a metallized magnetic core and a ceramic core which use a conductive medium to drive the adsorption of nickel ions. Background technique [0002] When metallized magnetic cores and ceramic cores (workpieces) are terminated with silver, they have the following disadvantages when they are traditionally electroplated with nickel or tin: [0003] 1) The quality of the product is not stable, it is easy to cause product damage, poor tin attachment, and poor tinning effect at low temperature; [0004] 2) The traditional process is greatly affected by equipment and personnel, and the production capacity is low; [0005] 3) During electroplating, the nickel potion of the traditional process needs to be heated to 50-60°C. When heating, it is open-type heating, which will generate a large amount of hot gas, causing a large amount of gas to volatilize, and the waste gas treatment is diff...

AI Technical Summary

Problems solved by technology

[0003] 1) The quality of the product is not stable, it is easy to cause product damage, poor tin attachment, and poor tinning effect at low temperature;

[0004] 2) The traditional process is greatly affected by equipment and personnel, and the production capacity is low;

[0005] 3) During electroplating, the nickel potion of the traditional process needs to be heated to 50-60°C. When heating, it is open-type heating, which will generate a large amount of hot gas, causing a large amount of gas to volatilize, and the waste gas treatment is difficult, which is not conducive to environmental protection, and The dispersive discharge of nickel is large, which is easy to cause human allergies and has a great impact on the skin of workers, which is not conducive to human health

[0006] 4. The waste water treatment load is heavy, and it is easy to produce a large amount of nickel-containing waste water. The environmental protection treatment is difficult, which is not conducive to the concept of green and clean development

[0007] 5. Distributed electroplating is traditional, and waste gas is difficult to collect and treat
