    摘要: A printed circuit board package structure includes a substrate (110) having a first surface (111) and a second surface (113), a ring-shaped magnetic element (120), an adhesive layer (130), conductive portions (140) and conductive channels (150). The first and second surfaces respectively have first (114) and second (116) metal portions. A ring-shaped concave portion (112) is formed on a position not covered by the first metal portions of the first surface. The ring-shaped magnetic element is placed in the ring-shaped concave portion. The adhesive layer covers the first metal portions and the ring-shaped magnetic element. The conductive portions are formed on the adhesive layer. The conductive channels penetrate the conductive portions, the adhesive layer, and the substrate, and are respectively located in an inner wall (122) and outside an outer wall (124) of the ring-shaped concave portion. Each of the conductive channels includes a conductive film (152) electrically connects to the aligned conductive portion and second metal portion.
