Lamination Systems With Temperature-Controlled Lamination Rollers

摘要

A lamination system may be provided for attaching a rigid structure to a compliant structure. The system may include a fixed stage for holding the rigid structure and a movable stage for holding the compliant structure. The rigid structure may be a rigid substrate or an assembly of substrates such as a sensor-on-cover-glass assembly for a touch-sensitive electronic device display. The compliant structure may be a sheet of optically clear adhesive. The system may include a temperature-controlled lamination roller attached to the movable stage. The roller may be heated or cooled during lamination operations. The compliant structure may be laminated onto the rigid structure by pressing the compliant structure onto the rigid structure using the roller while controlling the temperature of the roller. The roller may be heated while pressing the compliant structure onto the rigid structure to minimize the risk of lamination defects.

1. A lamination system for laminating a hard substrate to a soft substrate, the system comprising:
a fixed mounting stage for mounting the hard substrate; a movable mounting stage for mounting the soft substrate; a temperature-controlled lamination roller having at least one temperature control element; and computing equipment coupled to the movable mounting stage and the temperature-controlled lamination roller, wherein the computing equipment is configured to control the temperature of the temperature-controlled lamination roller while moving the movable mounting stage along a direction parallel to a surface of the hard substrate.
