Description

technical field [0001] The invention belongs to the technical field of electrodeposition and electroetching processing, and in particular relates to a processing device and a processing method based on an electric field. Background technique [0002] In the existing electrochemical deposition, micro-electroforming or electrolytic etching process, the process is relatively complicated and the cost is high, and there are generally problems of lack of flexibility and insufficient precision. [0003] For example, in the process of electroforming, it is usually necessary to customize anodes, and different models of electroforming need to customize different anodes, which is costly and time-consuming for a small number of models. Typical electrolytic processing, such as mask electrolysis, requires multi-step processes such as gluing, exposure, and development of the anode, which is time-consuming, laborious, and costly. Similarly, different anode mask patterns need to be customiz...

Problems solved by technology

Using this process, it is not possible to selectively produce patterned forming foils, nor can it produce forming foils with selective thickness arrangements

For example, when conventionally making printed circuit boards (PCBs), copper foil is often combined with insulating materials (such as organic resins) to form copper clad laminates, and then coated with photosensitive oil or photosensitive dry film, exposed, developed, and etched. The preset copper layer pattern can only be generated through complex processes such as film removal and fading. Each layer of copper pattern often needs to be customized negative film (such as film, silver salt photosensitive film), and a variety of chemical materials are used for multiple cleanings in the process. The process is cumbersome , inflexible and not environmentally friendly
