Abstract: A metal clip assembly, a semiconductor device assembly, a method for manufacturing the same, and an application thereof are provided. The metal clip assembly includes metal clip units. The metal clip units include connectors, pins, and at least one group of spatial positioning grooves. By sharing the at least one group of spatial positioning grooves, a spatial structure of the metal clip assembly is simplified, and it facilitates convenient positioning on the metal frame. Positions of the metal clip assemblies are positioned in a horizontal direction through cooperation between X-direction positioning grooves and X-direction positioning pins, and cooperation between Y-direction positioning grooves and Y-direction positioning pins. Further, positions of the metal clip assemblies in a height direction is positioned by configuration of positioning bumps. Through a surface tension of melt solder paste, an automatic alignment of the metal clip assemblies is completed on the metal frame.

Abstract: A measurable micro-communication device includes a main body, a camera and a measurement sensor, a display screen is provided at a front surface of the main body, and both the camera and the measurement sensor are configured at a top surface of the main body. Since the camera is configured at the top surface of the main body, thus if the measurable micro-communication device is lain on flat position, user can also take pictures by using the camera, without picking up the device. Thus the camera operation is more convenient. Furthermore, since the measurement sensor is configured at the top surface of the main body, by which distance and temperature can be measured, thereby enriching the utility function of the micro-communication device to satisfy the increasing user demands.

Abstract: A wearable device made by amorphous alloy with antibacterial function includes a functional part adapted for implementing using functions of the wearable device; and an amorphous alloy housing configured out of the functional part and adapted for cladding the functional part to prevent the functional part from directly contacting with a user. Since the wearable device has the amorphous alloy housing covering on the functional part, thus the amorphous alloy housing rather than the functional part will contact with the user skin directly. As the amorphous alloy has excellent bactericidal capability, thus user wearing such a wearable device will get a good user experience.

Abstract: A convenient and versatile method for preparing complex metal oxides is disclosed. The method uses a low temperature, environmentally friendly gel-collection method to form a single phase nanomaterial. In one embodiment, the nanomaterial consists of BaAMnBTiCOD in a controlled stoichiometry.
