Abstract:
PROBLEM TO BE SOLVED: To provide a connection structure of a circuit board which can efficiently utilize a board area and is excellent in workability of inspection. SOLUTION: A plurality of terminals 17 are juxtaposed and provided on the surface of a printed board 12. A plurality of terminals 21 matched with the terminals 17 on the printed board 12 are juxtaposed and provided on the surface of a TCP 13. Both types of terminals 17, 21 are mutually connected in a state of superposition. An index side edge portion 22 formed so that its one part is shifted from the other by a predetermined dimension along the arrangement direction of the terminals 21 is provided on a side edge portion in the terminals 21 of the TCP 13. The shift quantity between the terminals 17 and 21 can be confirmed while using the index side edge portion 22 as a guide. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a wiring board in which the number of terminal lands can be increased, without being limited by the number of interconnect lines which can be passed between a plurality of terminal lands and the terminal lands can be arranged at high density, and to provide an ink jet head mounted with the wiring board. SOLUTION: Interconnect lines for driving 21a, 21a, ... from a drive IC are passed between terminal lands 24, 24, ... and are connected to respective terminal lands 24, 24, .... When more interconnect lines than those which can be passed between terminal lands 24, 24, ... are required, the interconnect lines for driving 21a, 21a, ... from the drive IC are routed via the outside of the array of a plurality of terminal lands 24, 24, ... and are connected to respective terminal lands 24, 24, ....

Abstract:
PROBLEM TO BE SOLVED: To provide a flexible printed board and a cellphone in which the connection failure of a flexible printed board with a connector is reliably detected. SOLUTION: The cellphone comprises a FPC contacts connector 71 containing a butt 72 and a connection pin 73, and a flexible printed board 51 connected to the FPC contacts connector 71. The flexible printed board 51 has a surface 53a and an end 54, and further contains a connection part 53 which is inserted into the FPC contacts connector 71 so that the end 54 abuts on the butt 72, and a plurality of conductors 55m, 55n which are formed on the surface 53a and come into contact with a point of contact of the connection pin 73. The plurality of conductors 55m, 55n are provided so that a distance from the conductor 55n disposed at the outermost end of the plurality of conductors 55m, 55n to the end 54 is greater than a distance from the other conductor 55m to the end 54. The cellphone 1 further comprises a predetermined inspection circuit. COPYRIGHT: (C)2005,JPO&NCIPI
