n the EMC design of products, one of the key points in the structural design is that when the structural bodies on both sides cannot complete a good lap, they usually need to be made up by sealing gasket. These sealing pads include conductive rubber (Fig. 1), wire mesh strip (Fig. 2), finger reed (Fig. 3), spiral tube (), multiple conductive rubber (), conductive cloth pad (Fig. 4), etc. When choosing what kind of electromagnetic sealing gasket to use, four factors need to be considered: shielding efficiency requirements, environmental sealing requirements, installation requirements and cost requirements. See Table 1 for characteristics comparison of different liner materials.
