Laser ablation / scribing techniques and / or related methods for coating the assembly before and after lamination

摘要

Certain exemplary embodiments of the invention include pre- and post-laminated assemblies, pre- and post-assembled insulating glass units, and / or glass in other products or the like to delay or prevent corrosion of the coating. The present invention relates to a technique for laser ablation / scribing the peripheral edge of a coating (eg, low emissivity, mirror, or other coating) on a substrate. For example, using a 1064 nm or other wavelength laser, a metal layer and / or a metallic layer within a low emissivity or other coating provided for an already laminated or already assembled insulating glass unit or other product. (Multiple), for example, a line can be scribed around the periphery. Scribing wires reduce electron mobility from the center of the coating to the environment, thus delaying, and sometimes even further preventing, the occurrence of electrochemical corrosion. Products, methods, and kits related thereto are also contemplated herein.
