Abstract:
A method of bonding an intermediate substrate to a thermoplastic member, comprising:placing a first surface of the thermoplastic member against a heating block; placing a first surface of the intermediate substrate against a second surface of the thermoplastic member; coupling a heat sensitive material to a second surface of the intermediate substrate; heating the first surface of the thermoplastic member to a predetermined temperature and allowing sufficient time for heat to transfer through the thermoplastic member to at least a portion of the first surface of the intermediate substrate; limiting the heating of the first surface of the intermediate substrate so as not to allow the heat sensitive material to be exposed to detrimental levels of heat; allowing the thermoplastic member and the intermediate substrate to cool, thus forming a permanent bond; and wherein the heat sensitive material is a layer of adhesive.
