Abstract
A circuit board includes a plate member capable of holding a printed circuit board, the printed circuit board including an electronic component, and a cooling member provided on the electronic component, the printed circuit board and the electronic component being positioned between the plate member and the cooling member; and a circuit provided to the plate member and allowed to be electrically connected with the printed circuit board.
Claims10
A circuit board comprising:
- a plate member configured to hold a printed circuit board on which an electronic component is directly mounted, and a cooling member provided above the electronic component and including a conductive plate or a conductive foil provided between a first member and a second member and a hole through which a fastening member that fastens the cooling member and the plate member together is allowed to extend from the first member to the second member, the printed circuit board including layered wiring layers provided above the first member and the second member, the printed circuit board and the electronic component being positioned between the plate member and the cooling member;
- and
- a circuit provided to the plate member and allowed to be electrically coupled with the printed circuit board,
- wherein the conductive plate or the conductive foil is thicker than each of the layered wiring layers.
