Description

[0001] The utility model relates to the technical field of circuit board manufacturing, in particular to a multi-layer soft board processing jig and plasma etching equipment. Background Art

[0002] As electronic products develop towards miniaturization, lightness, portability and multi-function, the demand for multi-layer soft boards (flexible printed circuit boards) with open cover structures continues to increase. In order to ensure the quality of the products, the degumming treatment of blind holes and through holes is crucial in the production process of multi-layer soft boards.

[0003] At present, plasma equipment is usually used to remove glue from blind holes and through holes in multi-layer flexible circuit boards; however, during the vacuuming process of the plasma equipment, bulging may occur in the glue-free area of ​​the open-cover flexible circuit board, thereby affecting the graphic area of ​​the product and causing product quality problems; in order to solve this technical problem, the existing technology usually uses FR4 material clips on the front and back sides of the substrate to manually protect the glue-free area to prevent bulging problems from occurring in the multi-layer flexible circuit board during plasma processing.

[0004] However, during the plasma processing, office fishtail clamps are needed to fix the multi-layer soft board and the FR4 clamp, which makes it difficult for the multi-layer soft board to be well inserted into the frame of the plasma equipment. On the other hand, the rigid FR4 substrate is clamped, which makes it easy for the multi-layer soft board to swing left and right during the plasma processing, and contact with the electrode of the plasma equipment, thus causing the multi-layer soft board to burn. Therefore, it is necessary to optimize and improve the above problems to ensure the quality and stability of the blind hole and through hole degumming treatment of the multi-layer soft board.
