  • Common problems of piezoelectric diaphragms:

    Today, let's talk about the common quality problems of buzzer films, so as to facilitate your purchase and distinguish the quality.

    1. Part of ceramic disc of buzzer film falls off:

    First: there is a problem with the glue of buzzer tablet. The glue quality is poor or the amount of epoxy resin adhesive is not enough

    Second: copper or steel sheet, nickel alloy sheet bending deformation.

    Third: when the ceramic sheet and substrate are bonded, the curing temperature and time are not enough or too much.

    2. piezoelectric ceramic disks has no sound:

    First: piezoelectric ceramic vibrating plate (silver plate) is not polarized

    Second: the piezoelectric ceramic vibrating plate (silver plate) is dark cracked, and the positive / negative pole of the silver plate is short circuited.

    Third: the piezoelectric ceramic vibrating plate (silver plate) is not bonded and cured well with the metal plates.

    FBelec avoid above problem in order to guarantee the quality for customers.
