<p><P>PROBLEM TO BE SOLVED: To ensure further miniaturization by enabling efficient component arrangement. <P>SOLUTION: A printed wiring board can change a circuit constitution by attaching either one of two electronic components selectively. When one of the electronic component is soldered to a first land 1 and a second land 2, a circuit I is selected. However, when the other electronic component is soldered to the second land 2 and the third land 3, the other circuit section II is selected whereby the second land 2 is employed for the soldering of both of the electronic components. Further, the spaces of arrangements of two sets of electronic components are superposed partially on a straight line, thereby permitting to contrive the saving of a space for arrangement. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
