Backplane and method for producing same
A backplane is for electrically connecting electrical components. An embodiment is directed to the backplane and to a method for producing the same. An embodiment of the backplane includes a carrier plate, conductor tracks, which extend on and/or in the carrier plate, and at least one cooling element arranged on a conductor track for cooling the conductor track.
Heat Sink, Board, Electronic Device, and Manufacturing Method
A heat sink includes a heat sink fin (HSF), a first heat sink plate (HSP), and a second HSP that is opposite to the first HSP. The HSF is located on the first HSP. The second HSP is flexible. Further, an elastic component is disposed between the first HSP and the second HSP. The second HSP is in contact with a heat source component (HSC). Thus, when the heat sink is placed on the HSC, the second HSP contacts the HSC, the second HSP is deformed because the heat sink and the HSC are pressed against each other, and the elastic component between the first HSP and the second HSP is compressed such that heat generated by the HSC is transferred to the heat sink.
