A semiconductor device package includes a carrier provided with a first conductive element, a second conductive element arranged on a semiconductor disposed on the carrier, and a second semiconductor device disposed on and across the first conductive element and the first semiconductor device, wherein the first conductive element having a surface that is substantially coplanar with a surface of the second conductive element.

Semiconductor package device and method of manufacturing the same

The present invention provides a measurement device for grinding wheel. One or more thickness measurement device is disposed slidably on a platform. A spinning device is disposed on the platform. A grinding wheel is fixed on the spinning device. The spinning shaft spins the grinding wheel. The one or more thickness measurement device measures the flatness condition of the grinding wheel. Furthermore, according to the present invention, a diameter measurement device is disposed inside the platform and measures the roundness of the outer periphery of the grinding wheel. Since the structure can be disassembled easily, the whole measurement device for grinding wheel can be carried conveniently. In addition, measurements can be performed by users on the site where the grinding wheel is located for real-timely understanding the real size and wear condition of grinding wheel.

Measurement device for grinding wheel

A fluid adjusting device is installed in a valve unit so as to control the volume or pressure of the fluid passing through the valve unit. The fluid adjusting device includes three parts retractably connected to each other and holes are defined through each of the three parts. By expanding or retracting the three parts, the holes can be exposed or hidden to adjust the volume or pressure of the fluid passing through the valve unit.
