Permeable conductive shield having a laminated structure
First Claim
1. A permeable conductive shield, comprising:
- a plurality of insulating spacers disposed in a plane with spaces between the insulating spacers;
an insulating sheet having a plurality of through holes, disposed on the plurality of insulating spacers; and
a conductive sheet having a plurality of through holes, disposed on the insulating sheet,wherein the through holes in the insulating sheet are aligned with the through holes in the conductive sheet and the spaces between the insulating spacers so as to allow airflow through the permeable conductive shield.

Abstract
A permeable conductive shield providing protection from electromagnetic interference and electrostatic discharge has a laminated structure suitable for application to the foil side or the component side of a circuit board. The laminated structure includes an array of foam spacers arranged with spaces between them, a layer of foam attached to the top of the spacers, a first insulating sheet on the layer of foam spacers; a conductive sheet on the first insulating sheet, and a second insulating sheet on the conductive sheet. Each of the layers has a multiplicity of through holes aligned with corresponding through holes in the other layers and with the spaces between the foam spacers so as to allow airflow through the structure. The layers are bonded together with intervening adhesive layers. A pressure-sensitive adhesive is applied to the bottom of the spacers for attaching the permeable conductive shield to the circuit board.
