Abstract

The invention provides a packaging structure, which includes a metal substrate, a core structure layer and packaging components. The core structure layer is configured on the metal substrate, and has an opening and a patterned conductive layer. The packaging element is disposed on the metal substrate and located in the opening of the core structure layer. The packaging component includes a plurality of external leads, and the external leads are electrically connected to the patterned conductive layer of the core structure layer. The outer surface of each outer lead is aligned with the upper surface of the patterned conductive layer.

Description

technical field [0001] The invention relates to a package structure, in particular to a package structure capable of embedding package components. Background technique [0002] When considering the overall thickness of the electronic device or package structure, it is necessary to discuss the construction method of the embedded components. Through the embedding of components, the volume of the package can be greatly reduced, and more high-functional components can be placed to increase the layout area of ​​the substrate surface, so as to achieve the purpose of thinning electronic products. Generally speaking, in the existing packaging technology using embedded components, it is necessary to first form an accommodating groove on the substrate, so as to arrange the components in the accommodating groove of the substrate. Afterwards, the step of filling insulating colloid is carried out, so that the components are embedded in the substrate. However, the embedded components of...
