  • the flexible PCB 120 provides a balanced, radio frequency tuned circuit that may be directly soldered onto each pin of the RJ45 jack 110, while the jack shield 130 provides shielding for the RJ45 jack 110 and the flexible PCB 120, as well as functioning as a chassis ground.
  • the RJ45 jack 110, the flexible PCB 120, and the jack shield 130 may provide functionality similar to a tuned waveguide and a tube through which communication signals may be transmitted, where an energy portion of the communication signal travels outside the tube through jack shield 130; and an information portion of the communication signal travels within the tube along the non-resistive gold wire; thereby allowing for high speed data signal speeds to be obtained. For example, it is envisioned that data speeds of 40 gigabits (Gbs) and beyond may be supported.
  • Gbs gigabits
  • RJ 45 communication jack is used below, the present communication jack is not limited to RJ 45 communication jacks and may be used in any type of high speed communication jack including, all class of modular RJ type connectors, Universal Serial Bus (USB) connectors and jacks, Firewire (1394) connectors and jacks, HDMI (High-Definition Multimedia Interface) connectors and jacks, D-subminiature type connectors and jacks, ribbon type connectors or jacks, or any other connector or jack receiving a high speed communication signal.

  • the gold plating is used to provide a corrosion-resistant electrically conductive layer on copper, which is normally a material that oxidizes easily.
  • a layer of a suitable barrier metal, such as nickel may be deposited on the copper substrate before the gold plating is applied. The layer of nickel may improve the wear resistance of the gold plating by providing mechanical backing for the gold layer.
  • the layer of nickel may also reduce the impact of pores that may be present in the gold layer.
  • gold plating may not only reduce signal loss, but may also increase the bandwidth from the skin effect where current density is highest on the outside edges of a conductor.
  • use of nickel alone will result in signal degradation at higher frequencies due to the same effect.
  • higher speeds may not be achieved in RJ45 jacks that use nickel plating alone.
  • a pin or trace plated only in nickel may have its useful signal length shortened as much as three times once signals enter the GHz range although some benefits of using gold plating over the copper path has been described herein, other conductive elements may be used to plate the copper paths.
  • platinum which is also non- reactive but a good conductor, may be used instead of gold to plate the copper paths.
