Solder joint of buzzer -----time and temperature

The soldering temperature and soldering time of the buzzer will directly affect the deformation coefficient of the buzzer, thus affecting the buzzer sound. May cause the buzzer sound to become small, no sound, hoarseness, etc.

In order to avoid the above problems, we hope that customers can refer to the soldering process parameter table to ensure the production quality.
