LAIRD Technologies, represented in Australia by RFI Industries , has released sculpted foam, UL94 VO-rated, fabric-over-foam shielding gaskets.
The sculpted foam offers a good compression set and a relatively soft compression load deflection (CLD). Low compression set results provide improved shielding effectiveness over the life of the gasket.
They are available in a variety of complex shapes, and are compliant with the European RoHS and WEEE directives that ban the use of brominated and heavy metal components in electrical and electronic equipment.
The low CLD properties of the gaskets reduces the potential for equipment or chassis wall distortion. When the gaskets are compressed beyond the recommended 50%, the compression force is reduced by half.
