Embodiment Construction

[0022] Described herein is an adhesive bond with a shear layer placed between two or more adhesive layers for fixedly, securely, and reworkably placing each removable component within an electronic device Agent stack. The disclosed adhesive stack allows for a reduction in the space within the electronic device that would be required to secure the assembly. The disclosed adhesive can also help identify components that may have been removed or replaced by unauthorized users.

[0023] The structures or enclosures used to secure components within the interior of electrical equipment are generally designed to facilitate easy removal and replacement of components. In many cases, these enclosures are designed to allow authorized persons (and only authorized persons) to release the fixture, remove a component, replace it with a new component, and then reattach the fixture. Ideally, this can be performed quickly and easily at a retail site. In many cases, the housing can be metal or...

Abstract

An adhesive stack comprises a shear layer positioned between two adhesive layers. The shear layer, comprised of a weak adhesive sub-layer positioned between substrate sublayers, is designed to fail upon application of a deliberate and appropriate shear force and before the failure of the adhesive layers. The adhesive sub-layer defines a width and / or length less than a width and / or length of another layer or sub-layer of the adhesive stack. The adhesive stack aids 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Patent Application No. 13 / 250,786, filed September 30, 2011, entitled "Adhesive Stack Having a Central Shear Layer," which was filed on August 4, 2011, and entitled "Adhesive Stack Having a Central Shear Layer" "Stack Having a Central Shear Layer," a continuation-in-part of U.S. Patent Application No. 13 / 198,586, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to electronic devices and, more particularly, to securing components within electronic devices. Background technique [0004] Electronic devices are assembled from many individual components. The components are generally housed within the housing interior of the electronic device. Standalone components often require both physical and electronic connections to electronics and other components. In order to reduce the size of an e...
