METHOD FOR MOUNTING CAPACITOR ON CIRCUIT BOARD, AND CAPACITOR MOUNTED CIRCUIT BOARD

PROBLEM TO BE SOLVED: To provide a method for mounting a capacitor on a circuit board and a capacitor mounted circuit board capable of reducing noise generated by the piezoelectric phenomenon of a laminated ceramic capacitor. SOLUTION: Lands 31a, 31b, 32a, and 32b for mounting a capacitor which are conductive to each other are formed on a front surface 3a and rear surface 3b of a circuit board 3. Laminated ceramic capacitors 1 and 2 where the amplitudes of vibrations caused by a piezoelectric phenomenon are almost identical are so disposed as to almost overlap with the circuit board 3 in between on the lands 31a, 31b, 32a, and 32b of the front surface 3a and the rear surface 3b of the circuit board 3, for conductive connection. So, the vibration transferred to the circuit board 3 from one capacitor 1 and that transferred to the circuit board 3 from another capacitor 2 cancel each other, to prevent the circuit board 3 from resonating with the vibration. Thus, the audible sound whose sound pressure is larger than conventional one is significantly reduced. COPYRIGHT: (C)2004,JPO
