<p>PURPOSE:To mount without considering the disposing direction of a network by providing two common terminals at positions of equal interval reversely from the end of a board. CONSTITUTION:Terminals 3-1-3-10 of a network resistor 1 are disposed correspondingly at wiring pads 9-1-9-10 provided on a wiring circuit board 8, and the pads are soldered to the terminals. If a resistor 1 is placed reversely at 180 deg.C on the board 8 in a state that the terminal 3-5 corresponds to the pad 9-5, the terminal 3-10 is soldered correspondingly to the pad 9-5. In this case, since the terminals 3-5, 3-10 are commonly connected from a conductor pattern 4 as a common terminal, no failure occurs, and no erroneous wiring occurs. Thus, when the resistor 1 is mounted, it is not necessary to consider its direction.</p> |
