Publication number: 20070114057Abstract: A printed wiring board on which a pattern can be formed favorably by printing and soldering even where a small part of the 1005 size or less is mounted. The printed wiring board includes a substrate; a pair of soldering lands on the substrate, the soldering lands being spaced from one another with a first side of one land opposing a first side of another land; and a mounted part having a pair of electrodes on opposite ends thereof soldered to the respective lands. A wiring line is connected to each soldering land, and an insulating element overlies the wiring lines. The insulating element has openings formed so as to expose the soldering lands therethrough. Wiring line connection elements are individually connected to only the first sides of the lands. Each insulating element opening has an edge positioned outside of the corresponding land and on the inner side of the corresponding wiring line connection element.Type: ApplicationFiled: September 8, 2006Publication date: May 24, 2007Applicant: Sony CorporationInventor: Yoshinari Matsuda

Patent number: 6924440Abstract: An apparatus for electrically connecting an electronic element and a base includes an electrode region and a terminal region proximate the electrode region. A conductive paste is deposited on at least a portion of the terminal region. The conductive paste has an oxidation-reduced region thereon, formed by application of an acid to the conductive paste. An oxidation-prevention layer is formed on the oxidation-reduced region by deposition of a flux on the oxidation-reduced region, application of a solder to the flux, and blowing of a heated gas by the solder. The oxidation-prevention layer is adapted to bond the electrode associated with the electronic element to the conductive paste by soldering, when the electrode is present in the electrode region.Type: GrantFiled: March 28, 2003Date of Patent: August 2, 2005Assignees: Sony Corporation, Sony Electronics, Inc.Inventor: Yoshinari Matsuda
