Carbon Fiber Electronic Interconnects

Abstract :-
Carbon fiber is an emerging material in electrical and electronics industry. It has been used as contact in many applications, such as switch, potentiometer, and commutator brush. A new technique of electronics interconnect is developed, with carbon fiber as a conductive medium. This carbon fiber interconnect can provide interconnection between two planes in different levels of electronics packaging, from semiconductor die, substrate, packaged component to printed circuit board. For example, it can provide a separable interconnect between a land grid array (LGA) or ball grid array (BGA) IC package to a printed circuit board, as an LGA or BGA socket.

Electromagnetic Piston Engine Car

The electromagnetic piston engine according to the present invention in one aspect comprises a cylinder and a piston, each made of a magnetic material, a cylinder electromagnet having an inner wall of the cylinder magnetisable to a one magnetic pole, and a piston magnetization unit for magnetizing a portion of the piston engage able with the cylinder to a single magnetic pole in a fixed manner, in which the piston is transferred in a one direction by creating a magnetic attraction force between the cylinder and the piston by exciting the cylinder electromagnet; Continue reading Electromagnetic Piston Engine Car
