Abstract:
An adhesive stack may comprise a shear layer positioned between two adhesive layers, wherein the shear layer is designed to fail upon application of a deliberate and appropriate shear force and before the failure of the adhesive layers. The adhesive stack may aid in securing components within an electronic device to prevent movement of the component when the device is dropped, hit, or bumped. The adhesive stack may occupy minimal space within the device, and reduce the cost of securing the component within the device's interior. The adhesive stack may allow for replacement of the component by an authorized person applying an appropriate and deliberate force. The adhesive stack may aid in identifying components replaced by an unauthorized person.
