The invention relates to a reworking method. The reworking method is used for reworking of the touch module, the touch module comprises a cover plate, a touch structure and a bonding layer, the touchstructure comprises a touch layer and a flexible circuit board, the touch layer comprises a touch display area and a touch binding area located on one side of the touch display area, and the flexiblecircuit board comprises a first connecting part. The first connecting part of the flexible circuit board is bound and connected to the first side of the touch control layer in the touch control binding area, the first side of the touch control layer and the first connecting part of the flexible circuit board are bonded to the cover plate through bonding layers, and the reworking method comprises the steps: heating the touch control module, separating the touch layer, the flexible circuit board and the bonding layer from the cover plate in the touch binding area, and separating a whole body formed by the touch layer, the flexible circuit board and the bonding layer from the cover plate. The touch control layer, the flexible circuit board and the bonding layer are separated from the cover plate in the touch control binding area, so that cracks generated in the bonding area of the flexible circuit board and the sensing surface of the touch control layer due to the fact that the bonding layer pulls the flexible circuit board can be avoided.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a method for reworking a touch module. Background technique [0002] With the advancement of the information industry, electronic devices with multiple functions such as display, touch control and stereoscopic display are popular due to their higher convenience. Most of these electronic devices adopt an external touch screen design. For example, when an electronic device is required to have both a display function and a touch function, the touch panel and the display panel can be glued together to form the required electronic device. [0003] However, it has been found that in the electronic device with this structure, when the touch panel needs to be disassembled for rework or maintenance, the cover needs to be torn off first, and then the tape is torn off, and then the touch structure is separated from the display panel. . During the tearing off process of the cover plat...
