 Vibration motor

Vibration motor

The reason why mobile phones can vibrate mainly depends on the internal vibration motor of mobile phones.

With the mobile phone becoming more and more thin, the internal components are also required to be more compact and compact.

The use of glue bonding can replace the role of screws. On the one hand, the bonding is more reliable. On the other hand, glue can be coated in the narrow gap. Therefore, when the motor is small, there is no need to worry about its reliability. At the same time, coating glue on the vibration motor can protect the solder joints and small parts, play a waterproof and extend the service life.

Process characteristics

Taking the button type vibration motor as an example, this paper briefly describes the dispensing process applied in the button type vibration motor. Button motor needs to go through four dispensing processes, which are encapsulation of small components, bonding and reinforcement of chips, soldering and sealing, and FPC reinforcement.


Due to the small volume and limited internal space of vibration motor products, the packaging requirements for components are different from those of our common components. It only needs to cover a part of the component area in a specific position, during which strict glue quantity control and precise dispensing position control need to be ensured.


However, the difficulty coefficient of soldering process is higher. Due to the size of solder is not consistent, there is also a certain deviation in the position, if the conventional way of point encapsulation is used, it is easy to cause solder joint encapsulation and overflow, resulting in poor dispensing.


In view of the above situation, axxon, based on the long-term accumulated dispensing experience, adopts the method of combining dots and lines to help customers solve the problems of overflow and poor encapsulation.

In the aspect of vibration motor dispensing, valve and software processing system are the core. Axxon has self-developed core products, jet valve and piezoelectric valve, which can realize dispensing of various fluids and adhesives with high speed and controllable capacity.
