This process is generally implemented through the following operation process: first, the copper cover to be removed is formed on the flexible circuit board by laser cutting, and then the edge of the copper cover is blown up by hand-tear openings using tools such as jigs and air guns. Finally, the operator manually removes the copper cover to achieve the removal of the copper cover one by one. Operating according to this uncovering process consumes a lot of manpower, has low operating efficiency, and low production capacity. Mass production requires more manpower to cope with it. At the same time, different operators have different uncovering directions, which may cause quality problems in the product.

The cover-lifting jig includes a bottom plate for placing the flexible circuit board and a cover plate for pressing the flexible circuit board. The cover plate is provided with an opening for exposing the copper cover, and the opening can be a first opening corresponding to each copper cover, or a second opening corresponding to all copper covers at the same time. When the opening is the first opening, different types of flexible circuit boards need to be equipped with different cover plates, and thus multiple cover-lifting jigs need to be equipped; when the opening is the second opening, when the copper cover in the middle of the flexible circuit board is lifted, due to the lack of downward pressure in the middle of the flexible circuit board, the middle of the flexible circuit board is easily lifted, which is not conducive to the separation of the copper cover from the flexible circuit board, and also easily leads to quality problems of the product.
