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 antenna packaging structure and a manufacturing method thereof. An antenna and a chip are respectively disposed on two sides of a substrate layer, antenna layers are formed by an antenna support member, a first antenna layer located above the antenna support member and a second antenna layer located below the antenna support member together, and interlayer dielectrics of the antenna support member and the antenna layers are low dielectric loss materials, so that a heterogeneous and isomerous antenna structure is formed, thereby reducing the problems such as current leakage and stray capacitance in the packaging structure caused by dielectric loss, and reducing a size of the antenna packaging structure.

Antenna packaging structure and manufacturing method thereof

The present invention provides a dual-substrate antenna package structure and a method for manufacturing the same. The package structure includes a main substrate and at least one antenna substrate. The antenna substrate is provided on a pad of the main substrate by an array of solder balls placed on the antenna substrate, at least one chip is electrically connected to the main substrate, and metal wiring provided on the main substrate electrically connects the pad to the chip. The array of solder balls includes support solder balls and conventional solder balls, and the support solder balls have a melting point high than 250° C. A spacing distance between the antenna substrate and the main substrate can be kept stable during the reflow soldering process and subsequent processes because the support solder balls having the high melting point can always maintain the stability of the structure during the reflow soldering process.
