[0044] The following disclosure provides many different embodiments to implement the different features of the present invention. The following disclosure describes specific examples of each component and its arrangement to simplify the description. Of course, these specific examples are not intended to be limiting. For example, if an embodiment of the present invention describes a first characteristic component formed on or above a second characteristic component, it means that it may include an embodiment in which the first characteristic component and the second characteristic component are in direct contact, and may also include an embodiment in which an additional characteristic component is formed between the first characteristic component and the second characteristic component, so that the first characteristic component and the second characteristic component may not be in direct contact.

[0045] It should be understood that additional operating steps may be implemented before, during or after the method, and in other embodiments of the method, some operating steps may be replaced or omitted.

[0046] In addition, spatially related terms may be used, such as "below", "below", "lower", "above", "above", "higher" and similar terms. These spatially related terms are for the convenience of describing the relationship between one (or some) elements or features and another (or some) elements or features in the drawings. These spatially related terms include different orientations of the device in use or operation, as well as the orientations described in the drawings. When the device is turned to a different orientation (rotated 45 degrees or other orientations), the spatially related adjectives used therein will also be interpreted according to the orientation after the rotation. Furthermore, when it is mentioned that a first material layer is located on or above a second material layer, it includes the situation where the first material layer is in direct contact with the second material layer, or there may be one or more other material layers in between. In this case, the first material layer and the second material layer may not be in direct contact. In some embodiments of the present invention, terms such as "connection", "interconnection", etc., related to bonding and connection, unless otherwise defined, may refer to two structures being in direct contact, or may refer to two structures not being in direct contact, wherein another structure is disposed between the two structures. Moreover, such terms related to bonding and connection may also include the situation where both structures are movable, or both structures are fixed.

[0047] It should be understood that although the terms "first", "second", "third", etc. are used herein to describe different elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Therefore, without departing from the technology of the present invention, the first element, component, region, layer or section discussed below can be referred to as a second element, component, region, layer or section.

[0048] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meanings as those commonly understood by those skilled in the art to which this disclosure belongs. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the background or context of the relevant technology and the present invention, and should not be interpreted in an idealized or overly formal manner unless specifically defined in the embodiments of the present invention.

[0078] The present invention utilizes an intermediary layer attached to the cover plate to fill the gap under the cover plate to achieve a buffering effect, so that the cover plate is not easily broken when impacted by external force, and the problem of fragments flying can be avoided at the same time. In addition, the same buffering effect can be achieved by attaching an intermediary layer to the circuit board routing area. The present invention utilizes the intermediary layer attached to the cover plate in the original structure, extends it to the gap under the cover plate, or attaches the intermediary layer to increase the strength of the cover plate, which can greatly reduce costs. Furthermore, the intermediary layer attached to the circuit board routing area can preferably be attached using a single-sided tape or a foam tape, or a gap can be left between the intermediary layer and the circuit board routing area to reduce the impact of the intermediary layer on the circuit board routing area.

[0079] The components of some of the above-mentioned embodiments are provided so that those of ordinary skill in the technical field to which the present invention belongs can better understand the viewpoints of the embodiments of the present invention. Those of ordinary skill in the technical field to which the present invention belongs should understand that they can design or modify other manufacturing processes and structures based on the embodiments of the present invention to achieve the same purposes and / or advantages as the embodiments introduced herein.
