Publication number: 20090151980Abstract: The invention discloses a flexible flat cable and the manufacturing method thereof. The Flexible flat cable is manufactured by the following steps of: forming a metal layer on an insulated base layer, then forming a protective layer on the metal layer which had been formed above the insulated base layer, to make the metal layer be covered between the insulated base layer and the protective layer for forming a composite shelter, then preparing a conducting layer and an insulated substrate, and then spreading an insulated glue layer on the bottom of the composite shelter and then combining the composite shelter, the conducting layer and the insulated substrate by a thermo-compression bonding process to make the conducting layer be covered between the insulated base layer and the insulated substrate for forming a flexible flat cable having the composite shelter.Type: ApplicationFiled: April 15, 2008Publication date: June 18, 2009Inventors: Yu Cheng Chin, Sheng Li Hung

Publication number: 20090151983Abstract: A cable grommet system for installation in data centers, offices and the like, for sealing cable openings in raised flooring, wall or ceiling panels, server cabinets, etc. to facilitate the installation and revision of wiring and cabling to server installations while minimizing losses of any provided conditioned air. A wide variety of grommet configurations is possible with a limited number of component parts. An advantageous acute angle mounting of sealing brushes enhances the sealing effectiveness thereof, particularly for smaller sizes of cable openings. In some embodiments, a novel arrangement of electrical conductors is incorporated into the grommet structures for dissipation of electrostatic charges, enabling the basic frame components to be formed of a flame retardant material.Type: ApplicationFiled: February 25, 2009Publication date: June 18, 2009Inventors: Arthur T.

Publication number: 20090151985Abstract: When package circuit boards are formed by dicing a circuit board sheet with a core substrate that conducts electricity, conductive material is not exposed from the outer side surfaces of the package circuit boards, thereby preventing electrical shorting of the package circuit boards. A method of dicing a circuit board sheet includes: a step of forming a circuit board sheet by forming a core portion that includes a conductive material and providing a wiring layer on the surface of the core portion; a step of forming concave channels in a thickness direction of the circuit board sheet from one surface of the circuit board sheet so as to pass through at least the core portion; a step of forming an insulating cover layer on a surface of the wiring layer and inside the concave channels; and a step of dicing the circuit board sheet within widths of the concave channels with positions of the concave channels as dicing positions.Type: ApplicationFiled: August 11, 2008Publication date: June 18, 2009Applicant: FUJITSU LIMITEDInventor: Kishio YOKOUCHI
