Abstract
The present invention discloses a method for laminating at least two polymer films. An intermediate assembly 40 is made comprising an adhesive film 20 and a dielectric polymer film 12. The method comprises the steps of: selecting an adhesive film 20 with a melting point T.sub.1, the adhesive film having inner and outer major surfaces 22, 24; selecting a polymer film 12, with a melting point T.sub.2, where T.sub.2 >T.sub.1, the polymer film having inner and outer major surfaces 14, 16; subjecting the inner surface 14 of the polymer film 12 to a high voltage electric discharge to form a treated inner surface; heating the polymer film 12 having the treated inner surface to a temperature greater than T.sub.1 ; aligning the inner adhesive surface 22 and the inner treated polymer surface 14 in opposed facing relationship; applying pressure to urge the films 12, 20 relatively together; and heating the pressed together films to a temperature greater than T.sub.1 ; whereby the adhesive film 20 adheres to the polymer film 12 to form the intermediate laminated assembly 40. The intermediate assembly 40 is bondable to another substrate 28 to form a resultant laminated assembly 42, which may be formed into an article such as connector 44 wherein the intermediate laminate 40 remains assuredly bonded to substrate 28.
