    Abstract: A part has a body unit; and one or more leg formed on the body unit. One or more slit is formed on the body unit adjacent to the leg. The legs are inserted to insert holes of a printed wiring board or the like and soldered thereto. Since the slit is formed adjacent to the leg, the heat applied to the leg for the soldering is not radiated by the body unit by virtue of the slit. Therefore, the part can be reliably attached to the printed wiring board or the like.

    Abstract: A thermistor with positive resistance-to-temperature characteristic used in a overcurrent protection circuit has electrodes on mutually opposite main surfaces and is mounted to a substrate having electrically conductive members such that deterioration of its voltage resistance due to heat emission can be controlled. A spacer with smaller thermal conductivity than the substrate and penetrated by a conductor piece with a small cross-sectional area is inserted between solder materials connecting to one of the thermistor electrodes. The other electrode is contacted by an elongated connecting member through its sectional surface transverse to its longitudinal direction such that the cross-sectional area of electrical conduction is reduced.

    Abstract: A printed wiring board and an electronic device using the same with which the formation of cracks in base portions of projecting external electrodes formed on lands on the printed wiring board is certainly prevented. With respect to a printed wiring board 11 having lands 16 formed in a wiring pattern where external electrodes 13 are to be formed and a pattern-protecting film 17 having openings 17a where the external electrodes 13 are to be formed, the opening diameter D1 of the openings 17a in the pattern-protecting film 17 is set greater by a predetermined dimension than the external diameter D2 of the lands 16 and a gap is thereby provided between each of the external electrodes 13 and the pattern-protecting film 17 so that the external electrodes 13 and the pattern-protecting film 17 do not make contact with each other and as a result there is no cracking of the external electrodes 13 caused by differential thermal expansion of the external electrodes 13 and the pattern-protecting film 17. An electronic module comprising the electronic device of the invention mounted on a mother board can be widely used by being incorporated into various types of electronic equipment.

    Abstract: A ball grid array (BGA) package which has a plurality of solder balls attached to solder landings that each have a number of tabs which extend from a center area of the landing. The tabs assist in a symmetric formation of solder balls that are formed on the landings. When constructing the package, a solder mask is applied to a bottom package surface before the application of the solder balls. The solder mask has a plurality of openings which expose the solder landings and are larger than the center area of the landings. Solder balls are then placed onto the solder landings and reflowed so that the balls become attached to the landings. The fully exposed center areas of the solder landings allow the solder to flow vertically along the outer walls of the landings, thereby providing a more robust solder joint. The exposed solder landings also allow a solder flux to be thoroughly cleaned after the solder balls are attached to the landings. Additionally, the land tabs insure an even solder flow about the solder landings to produce a symmetric uniform solder balls.

    Abstract: In a mounting board, two through-holes are formed which are used for inserting both ends of a supporting member for a vibrator. On a surface of the mounting board, a ground conductor pattern is formed. In the ground conductor pattern, two portions of arcs, where the ground conductor pattern is removed, are formed on respective peripheries of the two through-holes. Furthermore, on the mounting board, two connecting conductor patterns are formed on surfaces of portions defined by the two through-holes and so on, so as to extend from the ground conductor pattern. Both ends of the supporting member for the vibrator are respectively inserted into the two through-holes and soldered to two connecting conductor patterns.
