PRINTED BOARD WITH HEAT RADIATION PATTERN

摘要

PROBLEM TO BE SOLVED: To provide a heat radiating means for a motor which is applicable to a heat-nonconductive material such as plastic fixing the motor even if a heat sink is characterized in that materials which control a driving voltage for suppressing the heat radiation of the motor and fixing the motor are metal having a high heat emissivity.;SOLUTION: A flexible printed board 10 is composed of a heat radiation pattern part 11 and a wiring pattern part 12 for driving the motor; and the heat radiation pattern part 11 is copper foil used to wire an ordinary flexible printed board and wide enough to cover the heat radiation part width of the motor and the wiring pattern part 12 for motor driving is patterned to an ordinary width. One flexible printed board 10 having the wiring pattern part, 12 has a land 12a in pattern enabling the matching soldering between the electrodes of the motor and lead wires and the other has a land 12b in pattern enabling the matching pattern between the circuit board driving the motor and the lead wires.;COPYRIGHT: (C)2001,JPO
