Abstract:
1. A printed circuit board (PCB) having a through-hole between an upper side and a lower side of the PCB, comprising: at least one electronic component attached to the upper side, at least one heat-conducting member (HCM) for inserting into the through-hole, extending from the upper side to the lower side, and being thermally coupled with said electronic component, and the HCM comprising a substantially planar, disc-shaped top portion and tapered or recessed, ring-shaped bottom portion, wherein said top portion is thermally coupled with said electronic component and wherein said top portion comprises several projections radially extending from an outer edge of the top portion, said projections affixed the HCM to the PCB by penetrating into an inner wall enclosing the through-hole, and wherein the bottom portion has a final shape resulting from plastically deforming an origin shape of the bottom portion by pressing the HCM substantially perpendicular to the top portion via a planar pressing tools.
