A method for piercing a double sided adhesive tape is provided to remove a circle separation area of the double sided adhesive tape through an automatic machining process. A method for piercing a double sided adhesive tape comprises the steps of attaching the double sided adhesive tape on a PET sheet having a thickness of 75 micron, thereby forming a workpiece to be processed, primarily inserting the workpiece including the PET sheet and the double sided adhesive tape into a molding device to primarily pierce a part of a dual circle removal area, attaching a PET sheet to an upper surface of the double sided adhesive tape, secondarily inserting the workpiece into the molding device, and piercing the remaining part of the dual circle removal area by guiding the double sided adhesive tape along a guide hole of the PET sheet.
