1. A lid structure for electrically shielding an electrical component, comprising:
- a lid comprising electrically shielding and heat conductive material and having resilient properties;
the lid including a lower contact wall configured to be put in contact with the electrical component and a wall structure extending upwards from the lower contact wall and defining an upper inner region bounded in part by the wall structure;
at least one portion of the wall structure having a physical feature extending outwards to contact an edge defining an opening of a shielding can as the lid is inserted into the opening of the can and thereby spring bias the portion of the wall structure towards the upper inner region;
the wall structure also including a camming structure for contacting the can and biasing the lid down onto the electrical component when the lid is installed in the can; and
a heat dissipation surface extending from the camming structure.

Abstract
A construction and method are provided for electronically shielding an electronic component and for removing heat generated by the component. The construction and method involve the use of a shielding can, formed with EMI shielding material that surrounds the electronic component and a lid or cap that both contacts and forms a heat sink with the component and also provides a shielding effect as it acts as the cap for the shielding can.

16. A method of shielding and drawing heat from an electrical component, comprising:
-
locating an electrical component within a shielding can formed of electrically shielding material, having an opening defined therein;
disposing a lid formed of EMI shielding and heat conductive material into the opening, against the electrical component and in engagement with the can in such a manner that reactive force between the can and the lid urge the lid against the component.
