Electronic assembly

An electronic assembly, comprising:

• a first circuit board assembly, comprising a first circuit board and a first heat source disposed on the first circuit board;
• a second circuit board assembly, comprising a second circuit board and a second heat source disposed on the second circuit board, wherein the first circuit board and the second circuit board are spaced apart from each other;
• a heat sink, located between the first circuit board and the second circuit board and comprising a base and a plurality of heat dissipation fins, wherein the plurality of heat dissipation fins protrude from a side of the base, and the base is thermally coupled to the second heat source;
• and
• a thermally conductive frame, protruding from the side of the base, wherein two opposite sides of the thermally conductive frame are thermally coupled to the base and the first heat source, respectively, and the thermally conductive frame forms at least one heat dissipation channel.
