More practical. The main object of the present invention is to provide a substrate structure and a manufacturing method thereof, and to package the integrated circuit to achieve the purpose of improving the reliability of the package. The effect of increasing the thickness of the substrate, the beauty = :: 'is to provide-a type used in the integrated circuit package high soldering (SMT) process, so that tin tin can achieve the same degree of return, can improve the substrate fixed to printing Circuit board stability. Therefore, in order to achieve the above-mentioned object, the main features of the present invention include: a plurality of lower metal sheets arranged on each other, each lower metal sheet being provided with an upper surface and a lower surface; a plurality of upper metal sheets arranged on each other, Each upper metal sheet is provided with an upper surface and a lower surface, and the lower surface is correspondingly stacked on the upper surface of the lower metal sheet; and a colloid is used for the lower metal sheet and the upper metal sheet. The sheets are covered and adhered, and the upper surface of each upper metal sheet is exposed by the sealing compound, and the lower surface of each lower metal sheet is exposed by the sealing compound for electrical connection to the printed circuit board. If so, the above-mentioned effects and purposes can be achieved. This case can be understood more deeply by the following drawings and descriptions. Please refer to FIG. 2 for the iu formula. FIG. 2 ′ is a cross-sectional view of the substrate structure for integrated circuit packaging of the present invention. The metal sheet 26 and the sealing compound 32 are provided, wherein: the mother lower metal sheet 20 is provided with an upper surface 22 and a lower surface 24. An upper layer of metal sheet 26 is provided with an upper surface 28 and a lower surface 30. The lower surface 30 is superimposed on the upper surface 22 of the lower metal sheet 2 and corresponding to each other. An intermediate plate 33 is provided between the upper metal sheets 26, which is used to set an integrated circuit. —The sealing colloid 32 is used to cover the lower metal sheet 20 and the upper metal sheet 26, and to expose the upper surface 28 and the intermediate plate 33 of each upper metal sheet 26 from the j colloid 32, and each lower metal The lower surface 24 of the sheet 20 is formed by the sealing compound 22 to be electrically connected to the printed circuit board 34, and the signal of the integrated circuit is transmitted to the printed circuit board. For example, when packaging integrated circuits by using the substrate structure of the present invention: Because the substrate is composed of upper and lower metal sheets 26 and 20, its thickness is thicker, which can more effectively prevent external adverse factors (temperature , Humidity) affect the integrated circuit, electrical characteristics, so that the package can get a better 7-reliance and ¥ 4 package is completed and soldered ($ μ τ) on the printed circuit board 32, can The solder 36 climbs onto the upper metal sheets 26 of the substrate, so better adhesion can be obtained. Please refer to FIG. 3, FIG. 4, and FIG. 5. In this embodiment, a plurality of lower metal sheet groups 42 are formed on the acoustic metal by stamping or etching. Each of the lower metal sheet groups 42 is formed with a plurality of The sheets 20 are arranged on each other; and an upper metal sheet group 46 is formed by punching or etching on an upper metal sheet 44, and each upper metal sheet group 46 is formed with a compound
