Abstract

The invention discloses a metallic micro component pickup method based on electrochemical deposition, relates to the metallic micro component pickup method, and aims to solve the problem that an existing metallic micro component is difficult to pick up and prone to damage. The pickup method comprises the following steps of calculating the minimum nozzle radius of a pipette capable of successfullypicking up according to stress conditions of a pick-up object and selecting a pipette; and calculating steady-state current, deposition height and deposition time, and then switching on a power supplyfor pick-up. According to the metallic micro component pickup method, when metallic micro components are required to pick up, the adopted pipette is small in size, and can pick up the metallic microcomponents of various types so that have application in producing complex micro electro mechanical system, and meanwhile the metallic micro components are not damaged when being picked up. The methodis suitable for picking up metallic micro components.

Description

technical field [0001] The invention relates to a method for picking up metal micro components. Background technique [0002] Metal micro-components refer to micron-scale components, and the more common ones are wire-shaped metal micro-components, such as micro-copper wires. When assembling metal micro-components, it is generally necessary to use tools to pick them up. After picking up, the micro-components are required to be flipped, moved or aligned with the tool, and the micro-components must not be dropped or damaged during the operation. [0003] The existing pick-up method is to use mechanical operating tools such as micro tweezers to clamp the operating object to achieve movement, but the micro-components are small in size, and the mechanical operating tools are relatively large in size. It is easy to cause irreversible damage to the micro-components, and the drop of the micro-components is easy to occur. Therefore, the existing mechanical operating tools can only r...
