Aluminum EMI / RF shield

摘要

A shield made from aluminum (AL) or an aluminum-based alloy coated with a solderable plating such as nickel or tin provides thermal improvement over existing shielding materials. The shield for circuitry on a circuit board comprising an aluminum material plated with a solderable material, the shield providing electromagnetic interference and radio frequency interference shielding and heat transfer when positioned over a circuit.

主权项

1. A shield for a circuit board comprising:
an aluminum substrate plated with a solderable material, the substrate forming a continuous, unitary, generally planar lid with bends forming depending side walls, the side walls extending over and around a fence and frictionally engaging an outside perimeter of the fence, the fence mounted to a circuit board to engage the shield over a circuit component to shield radio frequency interference, the continuous, unitary, generally planar lid, extending over the circuit component.
