Patent ID: 8137498

Claim:
A process for performing rigid-to-rigid substrate lamination implementing pressure-sensitive adhesive (PSA), comprising: pressurizing a first cavity formed at least in part by a first flexible membrane to a first pressure; pressurizing a second cavity formed at least in part by a second flexible membrane to a second pressure; applying the first pressure to a first laminate assembly stack via the first flexible membrane and the second pressure to a second laminate assembly stack via the second flexible membrane, each laminate assembly stack including a first substrate, a second substrate, and a PSA layer, the PSA layer being positioned between the first substrate and the second substrate; and applying a vacuum to the first and second laminate assembly stacks, wherein the applied first pressure, the applied second pressure, and the applied vacuum promote intimate contact between the first substrate and the second substrate of the first and second laminate assembly stacks via the PSA layer.
