[0047] In the following description, the terms "first," "second," and "third" are used only to distinguish one element, component, region, layer, or portion from another element, component, region, layer, or portion, and do not necessarily indicate a sequential order. In addition, relative terms such as "lower" and "upper," "inner" and "outer" may be used herein to describe the relationship of one element to another. It should be understood that relative terms are intended to include different orientations of the device in addition to the orientation shown in the figures. For example, if a device in a figure is turned over, an element described as being on the "lower" side of another element will be oriented on the "upper" side of the other element. This only represents a relative orientation relationship, not an absolute orientation relationship.

[0048] In the accompanying drawings, the width of some elements, regions, etc. is exaggerated for clarity. Throughout the specification, the same reference numerals represent the same elements. It should be understood that when, for example, an element is referred to as being "on" or "connected to" another element, it may be directly on or connected to the other element, or intermediate elements may also exist. Conversely, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intermediate elements.

[0049] Figure 1 It is a three-dimensional diagram of the first embodiment of the expandable input and output component. Figure 2 This is an exploded view of the first embodiment of the expandable input and output component. Figure 1 and Figure 2 As shown, the expansion I / O assembly 1 is assembled in an I / O area 510 of a motherboard 500 , which includes a bottom board-to-board connector 520 .
