摘要： A method of applying an adhesive to a substrate to mitigate entrapment of air bubbles during a vacuum lamination process is described. The method comprises contacting the adhesive to a surface of the substrate and applying a periodic force to the adhesive along the longitudinal direction creating first regions having a first adhesion strength to the substrate and second regions having a second adhesion strength to the substrate, wherein the second adhesion strength is less than 90% of the first adhesion strength.
