Abstract
An electronic appliance includes a circuit board mounted with an electronic-circuit component. The circuit board is covered with a shield, and a metallic heat-dissipating member is arranged on the electronic-circuit component. The shield is grounded on the circuit board, and arranged such that at least one of the surfaces is in the vicinity of the heat-dissipating member. The heat-dissipating member is grounded on the circuit board by a ground member, and at the periphery of the ground member, magnetic members are arranged.

An electronic appliance having a circuit board, an electronic-circuit component mounted on said circuit board, and a metallic heat-dissipating member placed on said electronic-circuit component for dissipating heat generated in said electronic-circuit component, comprising:
- a shield covering said circuit board being grounded and on said circuit board, and arranged such that at least one surface of the shield is positioned in a vicinity of said heat-dissipating member, wherein the heat-dissipating member extends through and outward from the shield;
- a ground member for grounding said heat-dissipating member on said circuit board, wherein said ground member is in direct contact with a grounded surface of the circuit board;
- and
- a magnetic member arranged around a periphery of said ground member, wherein the periphery and the magnetic member are covered by the shield.
An electronic assembly comprising:
- a printed circuit board;
- an electronic-circuit component mounted on said circuit board;
- a grounded, conductive heat sink attached to said electronic-circuit component, said heat sink including a ground member in direct contact with a grounded surface of the printed circuit board;
- a grounded, conductive electromagnetic shield covering the electronic-circuit component,
- wherein the heat sink extends through a slit in the shield and is attached to the electronic-circuit component and wherein a periphery of the heat sink is covered by the electromagnetic shield, and
- a magnetic member adjacent a periphery of the ground member of the conductive heat sink, wherein the magnetic member and heat sink are electromagnetically coupled and the magnetic member is between the electromagnetic shield and the electronic-circuit component.
