従来、この種の集積回路の放熱実装構造は、図2に示すように、プリント基板 11と集積回路12の各端子をハンダ付けで固定し、集積回路12の裏面がプリ ント基板11と密着することにより放熱していた。 Conventionally, in this type of heat dissipation mounting structure for an integrated circuit, as shown in FIG. 2, the terminals of the printed circuit board 11 and the integrated circuit 12 are fixed by soldering, and the back surface of the integrated circuit 12 is in close contact with the printed circuit board 11. It was radiating heat.

上述した従来の集積回路の放熱実装構造は、プリント基板と集積回路の裏面の みの放熱を行っているため、放熱性があまり高くなく、また集積回路の小型化に より、集積回路自体に放熱器を取付けることが困難という欠点があった。 In the conventional heat dissipation mounting structure for the integrated circuit described above, heat is dissipated only from the printed circuit board and the back surface of the integrated circuit, so the heat dissipation is not very high. There was a drawback that it was difficult to attach the vessel.
