Abstract: An electrical circuit on a substrate (10), having at least one component (30, 40) attached to a conductor layer (20, 21, 22, 23, 24, 25), is proposed; the component is surrounded by depressions (50, 51, 60) in the conductor layer. In addition, a substrate having at least one conductor layer for attaching at least one electrical component is proposed, the conductor layer having depressions to provide a flow barrier for a connecting material which is used for attaching the component; the depressions surround an area for attaching the component, and are positioned at a distance from each other such that the component has room between them, without the depressions having to be covered by the component.
