1. A connection arrangement for forming a component carrier structure, the connection arrangement comprising:
a first electrically conductive connection element; and
a second electrically conductive connection element;
wherein the first connection element and the second connection element are configured such that, upon connecting the first connection element with the second connection element along a connection direction, a form fit is established between the first connection element and the second connection element that limits a relative motion between the first connection element and the second connection element in a plane perpendicular to the connection direction,
wherein at least one of the connection elements is a pillar having a non-circular cross-section,
wherein at least one of the connection elements is composed by a plurality of pillars, wherein some of the pillars are interconnected by elongated pads.
