Thin EMC Gaskets0 pages
Aluweave is a versatile, highly conductive gasket
medium produced by filling a woven aluminium mesh
with silicone, fluorosilicone or neoprene rubber. It is
particularly useful where thicker gaskets are
unsuitable but, because it is woven, it is not viable for
'landwidths'of less than 3mm for die-cut gaskets.
Surface irregularities should not exceed 0.05mm. This
material is generally supplied as pre-cut gaskets
constructed to the customer's specific requirements
but can also be supplied in sheets. Connector gaskets
in the DC Series include Aluweave materials.

GA Shielding
Applications:
Aluweave is used for connector gaskets and other'thin'gasket
applications. If aluminium is unsuitable because of galvanic compatibil-
ity or shielding effectiveness, the expanded Monel based GX Shielding
may be more appropriate.
Aluweave gaskets provide good 'point contact'where each crossover
occurs, while the rubber filler ensures excellent environmental sealing.
Aluweave, like nearly all other conductive gasket materials, should not
be fixed with a conductive or pressure sensitive adhesive and should
be fixed as a friction fit utilising the fixing screws to position the gasket
before tightening.
