The present invention provides a packaging structure and a manufacturing method thereof. The packaging structure includes an interposer, chips, and warpage adjustment structures, wherein the interposer includes a first surface and a second surface opposite thereto, and the chips are electrically connected to the first surface of the interposer; the warpage adjustment structures are symmetrically distributed with respect to a center of the first surface; and each of the warpage adjustment structures include a warpage adjustment piece and/or a cavity filled with a plastic packaging material, the warpage adjustment piece is disposed on the first surface, and the cavity is located outside conducting structures and sinks inward along the first surface. By cooperation between the warpage adjustment pieces and the cavities filled with the plastic packaging material, the warpage of the interposer in horizontal and vertical directions can be reduced.

Packaging structure and manufacturing method thereof

The present invention provides an SIP package structure. The SIP package structure comprises a first module, a second module and a shielding assembly, wherein the first module and the second module are horizontally distributed or vertically stacked; electromagnetic sensitive frequencies of the first module and the second module are different; the shielding assembly comprises a first shielding structure covering the first module and a second shielding structure covering the second module; and at least part of the first shielding structure and/or at least part of the second shielding structure are/is disposed between the first module and the second module.

SIP package structure

The present invention provides a fan-out package structure and a method for manufacturing the same. The fan-out package structure includes at least one chip and at least one redistribution layer on a functional surface side of the chip, and the redistribution layer includes a dielectric layer and a metal wiring layer distributed within the dielectric layer. The fan-out package structure further includes at least one dummy wafer on the redistribution layer, and the dummy wafer is insulated from the chip and in contact with the metal wiring layer. By providing the dummy wafer on the redistribution layer and configuring the dummy wafer to connect to the metal wiring layer, the dummy wafer can not only function to support the structure and suppress the warpage, but also form a continuous heat dissipation channel, thereby improving thermal management capability of the fan-out package structure.

Fan-out package structure and method for manufacturing the same

The present invention provides a package structure and a method for manufacturing the same. The package structure includes at least two electrical elements, a second reconstruction layer, and a metal lead frame, wherein at least one of the electrical elements is a chip, at least one of the electrical elements has a first reconstruction layer, and the second reconstruction layer has a smaller pin pitch than that of the metal lead frame; the second reconstruction layer has a first surface and a second surface, a functional surface of the electrical element is disposed on and connected to the first surface, and at least one of the electrical elements is connected to the second reconstruction layer; and the second surface is disposed on and connected to the metal lead frame. A fan-out package structure is formed on the metal lead frame, which improves the heat dissipation capacity of the chip.
