Abstract

The invention relates to the technical field of electrolytic surface treatment, in particular to an electrolysis method of a continuous terminal. Through fully shielding one surface of a material beltthrough a first conveyor belt, and partially shielding the other surface of the material belt through a second conveyor belt, the part, extending out of the outer periphery of the second conveyor belt, of the material belt can be processed, so that the purpose of local processing is realized, and the problem that the existing equipment cannot effectively process the local part of the single surface of the material belt is solved; and the pulse periodic reverse current is applied to the local surface of a continuous terminal material for electrolysis, so that electrolytic precious metal on thesurface of the continuous terminal material is adjusted and controlled to have required uniform precious metal film thickness distribution and excellent corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of electrolytic surface treatment, in particular to an electrolytic method for continuous terminals. Background technique [0002] Since the precious metal surface treatment technology was popularized and applied in the electronics industry, it has developed rapidly. Especially the gold-plated surface treatment technology and process, because the gold-plated layer has good corrosion resistance, good ductility, solderability, electrical conductivity and thermal conductivity, and stable chemical properties, strong anti-tarnish ability, therefore, all kinds of gold-plated Various technologies and processes have been widely used in precision electronics industries such as smart phones, computers, automobiles, and aerospace, as well as general civilian electronic products such as TVs and refrigerators. In addition, they are also widely used in processing fields such as decorations. [0003] In order to make full...
