なって来ている。However, the heat generated from the chip elements in these conventional printed wiring boards is dissipated through the printed wiring board and the surface conductor, and the heat dissipation characteristics vary depending on the type of organic resin or ceramic that is the material of the board, but in particular, Thermal conductivity of resin substrates is generally low, resulting in little heat dissipation. On the other hand, alumina ceramic substrates are no longer compatible with recent highly integrated semiconductors.

装することＫより小型化を実現することもできる。As shown in Fig. 4 above, the heat generated from the chip element mounted on the metal plate (4) is conducted through the metal plate, is quickly absorbed, and is dissipated from the back surface of the metal plate. This is K. In addition, as shown in Figure 4, the printed wiring board on which the chip element is mounted is mounted in a hole for mounting electronic components, so the entire printed wiring board on which the chip element is mounted becomes thinner. Moreover, it is also possible to achieve a smaller size than by directly mounting integrated circuit elements.
