A method of enhancing adhesion of a molding material (202) with a substrate (102) is provided. The method includes forming one or more perforations (108) on the substrate (102), forming a coat of an affinitive material on at least one of the perforations (108), and filling the molding material (202) in the perforations (108). The affinitive material has an affinity for the molding material (202). Therefore, the molding material (202) adheres to the coat of the affinitive material. |
