Abstract: In a method for patterning a reel-to-reel strip in an automatic manufacturing process, a reel-to-reel strip is stuck onto a support plate having a low-tack adhesive. A laser beam is used to pattern the reel-to-reel strip. Carbon residues and/or cut pieces generated during a process of patterning the reel-to-reel strip are stuck on the support plate having the low-tack adhesive. Therefore, the carbon residues and/or the cut pieces will not fall down to other parts of the reel-to-reel strips during the automatic manufacturing process. Thus, it does not need to remove the carbon residues and/or the cut pieces from the reel-to-reel strips.
