Abstract: A package structure includes a thermal dissipation structure, a first encapsulant, a die, a through integrated fan-out via (TIV), a second encapsulant, and a redistribution layer (RDL) structure. The thermal dissipation structure includes a substrate and a first conductive pad disposed over the substrate. The first encapsulant laterally encapsulates the thermal dissipation structure. The die is disposed on the thermal dissipation structure. The TIV lands on the first conductive pad of the thermal dissipation structure and is laterally aside the die. The second encapsulant laterally encapsulates the die and the TIV. The RDL structure is disposed on the die and the second encapsulant.

Abstract: A measuring device includes a furnace, a draining vessel, a loader and a computing system for physical properties. The draining vessel with molten metal fluid is in the furnace. The loader accumulates the molten metal fluid from the draining vessel. The computing system includes a recording unit, transform unit, computing unit and processor. The recording unit records the vessel information. By the assumed physical parameters and the vessel information, the transform unit transforms a weight of the molten metal fluid in the loader into a first length criterion, and the computing unit simulates the flowing of the molten metal fluid to have a second length criterion. The processor minimizes the difference of the first and the second length criterion by changing the assumed physical parameters. The physical properties of the molten metal fluid are determined when the difference is minimized.
