  • soldering technology of piezo element:

    As we all know, Piezoelectric Disk can be used for soldering.

    The welding process requirements of FBelec's loud piezo ceramic element are as follows:

    First, the piezoelectric element must be checked carefully, and only qualified products can be used.

    Secondly, do not touch the piezo tone with bare hands, and be sure to wear rubber gloves, because the sweat on your hands will corrode the  piezo sensor and cause oxidation.

    Furthermore, the solder joints are required to be full and round,smooth,There is no virtual welding and false welding, and there is no sharpening of the solder joints.False soldering will cause the lead to fall off,the position of red, black and yellow lines should not be welded wrong!

    Finally, the silver-plated coating is particularly vulnerable to damage, so soldering should be done quickly.

    FBelec's piezoelectric element can be customized, no matter what specification you need, same quality as Murata's FBelec will do the best to meet you.
