Sound Components (Buzzer)Piezoelectric Buzzers: Precautions When Manually Inserting into Printed Circuit Boards

If the fixing part of a pin is broken, it is conceivable that an open circuit may occur. Because of this sound may fail to be emitted due to the pins being pushed into the product.

When attempting to insert the pins into the printed circuit board, if the pins do not enter the holes but instead strike the printed circuit board, a force will act to push the pins in the direction toward the inside of the product. If an excessively large force is applied in the direction toward the inside of the product, the fixing point of each pin will break, and the pins will be pushed into the product.
When the pins are pushed through the component, the two electrodes will touch the piezoelectric vibration plate, and a short circuit will occur, resulting in a malfunction.
