1. A method for manufacturing a packaging structure, comprising:
providing a first carrier plate, wherein the first carrier plate comprises a first outer wiring layer and a second outer wiring layer stacked in a first direction, the first outer wiring layer is electrically connected to the second outer wiring layer; forming two first conductive posts on the first outer wiring layer, the two first conductive posts arranged along a second direction perpendicular to the first direction, wherein each of the two first conductive posts comprises a first end electrically connected to the first outer wiring layer, a second end opposite to the first end, and a sidewall connected between the first end and the second end, a first insulating layer surrounds the sidewall of each of the two first conductive posts, the second end of each of the two first conductive posts is exposed from the first insulating layer, and a receiving groove is formed between the two first conductive posts; placing an embedded component in the receiving groove;
forming a second carrier plate on the first insulating layer containing the first conductive posts, wherein the second carrier plate comprises a third outer wiring layer and a fourth outer wiring layer stacked in the first direction, the third outer wiring layer is electrically connected to the second end of each of the two first conductive posts and the embedded component, and the fourth outer wiring layer is electrically connected to the third outer wiring layer; and electrically connecting a first outer component to the second outer wiring layer through a reflow soldering process, and electrically connecting a second outer component to the fourth outer wiring layer through another reflow soldering process, thereby obtaining the packaging structure, wherein after placing the embedded component in the receiving groove, the method further comprises: forming an insulating adhesive layer in a gap between the embedded component and the receiving groove, wherein forming the second carrier plate comprises: defining a first opening in the insulating adhesive layer; forming a second conductive post in the first opening, wherein the second conductive post is electrically connected to the embedded component; forming the third outer wiring layer on the insulating adhesive layer; and
forming the fourth outer wiring layer on the third outer wiring layer, and wherein the insulating adhesive layer is flush with the second end of each of the two first conductive posts.
