A method of manufacturing a component carrier includes a step of stacking and connecting a first component and a second component to one another to form a cluster and thereafter, a step of inserting the cluster into a cavity of a base structure. A component carrier has a base structure with a cavity; a cluster having a first component stacked and connected with a second component, wherein the cluster is arranged in the cavity. A height difference between opposing lateral sidewalls of the cluster is less than 15 μm.
