  • Publication number: 20240084447
    Abstract: A sealing article includes a body and a coating layer disposed on at least one surface of the body. The body comprises a polymeric elastomer such as perfluoroelastomer or fluoroelastomer. The coating layer comprises at least one metal. The sealing article may be a seal, a gasket, an O-ring, a T-ring or any other suitable product. The sealing article is resistant to ultra-violet (UV) light and plasma, and may be used for sealing a semiconductor processing chamber.

  • Patent number: 8764484
    Abstract: An electrical connector includes an insulative housing (3), a number of contacts (4) retained in the insulative housing (3) and a metallic shell (1) enclosing the insulative housing (3). The metallic shell (1) includes a number of peripheral walls and a soldering tab (15) extending therefrom. Each of the soldering tab (15) and the peripheral walls includes an intermediate layer (20), a first plating layer (21), a second plating layer (22) and a third plating layer (23). The third plating layer (23) covers both inner and outer sides of the second plating layer (22) of the peripheral walls for enhancing anti-wear properties while leaving the second plating layer (22) of the soldering tab (15) uncoated for wetting. Besides, a method of surface treatment of the metallic shell (1) is also disclosed.
