Abstract

The invention provides an electrical element for a computer data processing device. The electrical element comprises an element base layer, the element base layer is plated with a tin layer by adopting an electroplating process, the element base layer is electroplated in an electroplate liquid in the electroplating process, and a compact plating layer with the thickness of 5.0-10.0 microns is formed by electroplating. According to the electrical element for the computer data processing device and the manufacturing method of the electrical element, the element base layer is electroplated in theelectroplate liquid, the electroplate liquid adopts nickel sulfate and nickel chloride as base materials, and the dispersion of the electroplate liquid is improved by adding a dispersing aid, so thatthe dispersion effect of the electroplate layer on the element base layer is enhanced, and the bonding strength of the electroplate layer and the element base layer is improved.

Description

technical field [0001] The invention relates to the technical field of computer data processing, in particular to an electrical component for a computer data processing device and a manufacturing method thereof. Background technique [0002] In computer science, computer data refers to the general term for all symbolic media that can be input into a computer and processed by a computer program. . Computers now store and process a wide range of objects, and the data representing these objects has become more and more complex. Computer data generally has the following characteristics: duality, multimedia, and concealment; electrical components are basic elements in electrical circuits, usually individually packaged, and have two or more leads or metal contacts. Electrical components must be connected to each other to form an electronic circuit with a specific function, such as amplifiers, radio receivers, oscillators, etc. One of the common ways to connect electrical compone...
