Abstract: A connector for surface mounting to a circuit substrate is disclosed having an insulator, a center conductor mounted to the insulator; and a shielding shell externally mounted on the insulator. The shielding shell has a connecting portion and a mounting portion. The mounting portion has a connector mounting body with a shielding portion, a fluid communication well, and at least one opening. A plurality of solder legs are formed on the connector mounting body.

Abstract: In some embodiments, the present disclosure provides methods for fabricating carbon nanotube films. Such methods generally comprise: (i) suspending carbon nanotubes in a superacid (e.g. chloro sulfonic acid) to form a dispersed carbon nanotube-superacid solution, wherein the carbon nanotubes have substantially exposed sidewalls in the carbon nanotube-superacid solution; (ii) applying the dispersed carbon nanotube-superacid solution onto a surface to form a carbon nanotube film; and (iii) removing the superacid. Desirably, such methods occur without the utilization of carbon nanotube wrapping molecules or sonication. Further embodiments of the present disclosure pertain to carbon nanotube films that are fabricated in accordance with the methods of the present disclosure. Such carbon nanotube films comprise a plurality of carbon nanotubes that are dispersed and individualized.

Abstract: A center conductor for a surface-mounted electrical connector is disclosed having a contacting portion, a conductor body, and a soldering portion. The contacting portion is complimentary to a contacting portion receiving space of an insulating sleeve of the electrical connector. The conductor body has a first end connected to the contacting portion. The soldering portion is connected to an opposite second end of the conductor body, having a first solder receiving groove formed on an end surface thereof, and being complimentary to a soldering pad of a printed circuit board.

Abstract: Carbon nanotubes (CNT) fibers having a resistivity lower than 120 ??*cm are prepared by a wet spinning process including the steps of supplying a spin-dope of carbon nanotubes to a spinneret, extruding the spin-dope through at least one spinning hole in the spinneret to form spun carbon nanotubes fibers, and coagulating the spun carbon nanotubes fibers in a coagulation medium to form coagulated carbon nanotubes fibers. The carbon nanotubes fibers are drawn at a draw ratio higher than 1.0. The carbon nanotubes have a length of at least 0.5 ?m. The carbon nanotubes fibers can further have a resistivity lower than 50 ??*cm. At the same time, the CNT fibers can have high modulus.
