The invention discloses an alignment bonding method used for sticking a reinforcing steel sheet by FPC. The method comprises the following steps of S1, adding an alignment reference line for marking wastes on a film for pattern transfer, and manufacturing the alignment reference line and an FPC circuit together; S2, manufacturing raw materials into the FPC through an FPC manufacturing process according to the film; S3, editing a steel sheet material for manufacturing the reinforcing steel sheet, and engraving a regular reference point and the reference line on the steel sheet material to keepa distance between an edge of the steel sheet material and the reference line of the steel sheet material; S4, when the position of the single steel sheet material is edited, copying the positions ofother steel sheet materials according to makeup of an engineering drawing so as to edit the steel sheet material of the whole FPC; S5, carrying out first piece alignment precision confirmation on theedited reinforcing steel sheet; and S6, automatically adsorbing and bonding the reinforcing steel sheets in batches. A problem of accurate alignment when steel sheet reinforcement is larger than a product appearance is solved.
Description
technical field [0001] The invention relates to the technical field of flexible circuit board manufacturing, in particular to an alignment lamination method for pasting reinforcing steel sheets for FPC. Background technique [0002] In the FPC (flexible circuit board) manufacturing process, generally FPC will paste steel sheet reinforcement or other reinforcement on the back of the pad area to enhance the hardness, so as to improve the flatness of FPC and provide reliability guarantee for SMT printing. [0003] However, for steel reinforcement with large shape and FPC with small shape, the FPC is underneath, and the steel sheet blocks the FPC shape during alignment, so it is impossible to confirm whether the alignment is accurate, which will cause many problems of poor quality due to poor alignment accuracy. [0004] The information disclosed in this Background section is only intended to enhance the understanding of the general background of the present invention, and shoul...
