Abstract
Abstract A knitted or braided electromagnetic shielding material is formed by interweaving metallic or metal-clad wire rods, and each wire rod has a solder-plated layer on its surface. By heating the knitted or braided material, the wire rods are securely soldered to one another, thus preventing the knitted or braided material from loosening or disentangling, Furthermore, the contact resistance between the wire rods is reduced by the solder connections, thus enhancing the electromagnetic shielding effect of the knitted or braided material and further causing no difference in the electromagnetic shielding effect of the knitted or braided material in relation to its weaving direction. An electromagnetic shielding gasket clad with the knitted or braided material can be easily secured to a housing of electronic components, by using the solder-plated layers of the wire rods to melt the gasket thereto.
