Abstract
A printed wiring board having electronic circuit devices (13, 44) such as semiconductors including a heat sink forming a housing (32, 36) for the printed wiring board, one of the electronic devices (13) being mounted on one portion (12) of a heat spreader that is formed of a material having high thermal conductivity, another portion (10) of the heat spreader forming a thermal energy flow path to the heat sink, thereby lowering the junction temperature at the electronic device (13) and increasing the reliability of the wiring board.
