Systems and methods for protection of cosmetic surfaces and overflow prevention on electronic devices

摘要

Systems and methods for protection of cosmetic surfaces on electronic devices and adhesive overflow prevention are provided. In particular, an assembly for protecting a cosmetic surface can include a heat activated adhesive, such as a heat active film adhesive (“HAF”), which can be used to secure a mesh to the cosmetic surface. In some embodiments, a protective layer having a center layer laminated between two layers of heat activated adhesive can be used to protect the cosmetic surface from scratches caused by the mesh. In some embodiments, one or more hot shoes can be used to cross-link the heat activated adhesives to the mesh and the cosmetic surface. Because the shape of a shoe can influence the flow of heat activated adhesives during cross-linking, different shoes can be selected in order to minimize overflow in certain locations in the assembly.

主权项

1. An electronic device, comprising:
glass with ink on a first side of the glass, the glass comprising a through-hole; an adhesive layer having first and second sides, a protective layer between the first and second sides, and a cutout aligned with the through-hole; and a mesh secured to the first side of the glass to cover the through-hole, wherein the first and second sides of the adhesive layer comprise cross-linked heat activated adhesive that, on the first side, secures the adhesive layer to the first side of the glass, and on the second side, secures the adhesive layer to the mesh.
