| 20090011617 | CONNECTION STRUCTURE BETWEEN PRINTED CIRCUIT BOARD AND ELECTRONIC COMPONENT - Each wiring pattern is composed of a conductor layer and a tin plating layer, and includes a tip portion, a connection portion and a signal transmission portion. The width of the tip portion is equal to the width of the signal transmission portion, and the width of the connection portion is smaller than the widths of the tip portion and the signal transmission portion. The connection portions of wiring patterns and bumps of an electronic component are connected to one another, respectively, by heat-sealing when the electronic component is mounted. Respective distances A | 01-08-2009 |
| 20090096069 | Cof board - A COF board includes an insulating layer, and a terminal portion formed on the insulating layer. The terminal portion includes a first lead extending in a longitudinal direction, and a second lead extending in the longitudinal direction, and having a smaller length in the longitudinal direction than a length of the first lead in the longitudinal direction. The first leads are arranged in spaced-apart relation in a direction perpendicular to the longitudinal direction. The second leads are arranged in the direction perpendicular to the longitudinal direction to be interposed between the mutually adjacent first leads such that, when the mutually adjacent first leads are projected in an adjacent direction thereof, overlap portions where the second leads overlap with the first leads and non-overlap portions where the second leads do not overlap with the first leads are formed. Dummy leads are provided at the non-overlap portions. | 04-16-2009 |
| 20090195997 | PRINTED CIRCUIT BOARD AND METHOD OF MANUFACTURING THE SAME - A mounting region is provided at an approximately center of one surface of an insulating layer. A conductive trace is formed so as to outwardly extend from inside of the mounting region. A cover insulating layer is formed in the periphery of the mounting region so as to cover the conductive trace. A terminal of the conductive trace is arranged in the mounting region, and a bump of an electronic component is bonded to the terminal. A metal layer made of copper, for example, is provided on the other surface of the insulating layer. A slit is formed in the metal layer so as to cross a region being opposite to the electronic component and to divide the metal layer. | 08-06-2009 |
| 20090195998 | PRINTED CIRCUIT BOARD AND METHOD OF MANUFACTURING THE SAME - A mounting region having a rectangular shape is provided at an approximately center of one surface of an insulating layer. A plurality of conductive traces are formed so as to outwardly extend from the inside of the mounting region. A cover insulating layer is formed so as to cover the plurality of conductive traces in a periphery of the mounting region. An electronic component is mounted on the insulating layer so as to overlap with the mounting region. A metal layer is provided on the other surface of the insulating layer. Openings having a rectangular shape are formed in the metal layer along a pair of longer sides and a pair of shorter sides of the mounting region. The openings are opposite to part of terminals of the plurality of conductive traces, respectively, with the insulating layer sandwiched therebetween. | 08-06-2009 |
| 20090277667 | PRINTED CIRCUIT BOARD AND METHOD OF MANUFACTURING THE SAME - A mounting region is provided at a substantially center of one surface of an insulating layer. A metal layer is provided on the other surface of the insulating layer. A slit is formed to cross a region (an opposite region) of the metal layer that coincides with the mounting region and to divide the metal layer. A plurality of regions (large regions) of the metal layer divided by the slit each include a partial region (small region) of the opposite region. The area of each large region is set corresponding to the area of the small region included therein. Specifically, the small region having the area of A [%] with respect to the whole area of the opposite region is included in the large region having the area of (A±δ) [%] with respect to the whole area of the metal layer. Here, δ is an acceptable error range, and the acceptable error range δ is not more than (A×0.3). | 11-12-2009 |
