Ultra Thin EMI Shielding Materials

Ultra Thin EMI Shielding Materials Description:

Aluweave is a versatile, highly conductive gasket medium produced by filing a woven aluminium mesh with either silicone, flurosilicone or neoprene rubber. It is particularly useful where thicker gaskets are unsuitable but, because it is woven, it is unsuitable for 'landwidths' of less than 3mm for diecut gaskets. Surface irregularities should not exceed 0.05mm. This material is available in two thicknesses – 0.4mm and 0.5mm ± 0.1mm – and is generally supplied as pre-cut gaskets constructed to the customers specific requirements but can also be supplied in sheets. Connector gaskets in the DC Series include Aluweave materials.

Monex is an expanded Monel foil filled with silicone rubber. The exposed foil surface provides excellent conductivity combined with good corrosion resistance. Monex is also a 'thin' gasket medium, similar to Aluweave, and is particularly suitable for connector or waveguide gaskets where a pressure seal and EMI shield is required. The material cannot be effectively joined so gaskets should be cut in one piece wherever possible. Thicknesses of 0.5mm and 0.75mm are available and it can be supplied in sheet form.
To retain the strength of the foil, we recommend that a minimum land-width of 3mm should remain at any point around the edge of a Monex gasket. We also suggest that gaskets with intricate outlines are diecut at the factory.
