Abstract: The present invention provides a bump structure of chip disposed on a surface of a chip and comprises a plurality of connecting-bump sets. Each connecting-bump set includes a first connecting hum and a second connecting hump. The first connecting bump and the second connecting bump include corresponding blocking structures. While disposing the chip on a board member, the blocking structure of the first connecting bump and the blocking structure of the second connecting bump block the conductive medium and retard the flow of the conductive medium. The conductive medium is forced to flow between the first connecting bump and the second connecting bump and thus preventing the conductive particles in the conductive medium from leaving the surfaces of the connecting bumps. In addition, there is a flow channel between the first and second connecting bumps. One or more width of the flow channel is between 0.1 μm and 8 μm.

Abstract: The present invention relates to an optical imaging device, which comprises a plurality of module structures assembled to form an integral device. When not assembled, each of the module structures is an independent structure, respectively. The module structures include an optical module. When assembled, the optical module reflects an image and projects the reflected image. Since the optical imaging device according to the present invention comprises the module structures for assembling to form an integral device, the optical imaging device according to the present invention is not formed integrally. Accordingly, when the optical imaging device according to the present invention is disposed in a limited space and maintenance staffs need to maintain the optical imaging device, the module structures may be disassembled so that a portion of the module structures may be withdrawn from the limited space for facilitating maintenance and lowering maintenance cost.
