  • soldering method of Piezo Benders: As we all know, the piezoelectric ceramic plate can be welded. Let's summarize the welding method of the unimorph piezoelectric membrane. First, you need to apply a voltage to the Piezo-Electric Diaphragm using a wire. If using a soldering iron, the best temperature for soldering the wires to the sheet metal is 300°C for a few seconds.For ceramic electrodes, the same temperature value should be used, and the time should be 0.5 seconds or Shorter. The wire used should be as thin as possible, such as AWG32, because its function is to limit oscillation as the load of the piezoelectric ceramic . Secondly, the solder joint on the ceramic electrode should be as small as possible, and a thinner solder wire can be used, because more solder acts as the load of the piezoelectric ceramic buzzer, which will also affect the oscillation. FBelec's welding technology is unanimously recognized in the industry.
