PRODUCT ADVANTAGES ±3 g Force control accuracy DHROBOTICS The force generated by the voice coil actuator is proportional to the current. The voice coil actuator is combined with a high-performance guide rail. The coil and stator parts of the motor are non-contact and wear-free, and the force control accuracy of up to ±3 g can be achieved. Advantages Over Conventional Solution Take chip packaging as an example: Pain points The conventional chip pickup mechanism contacts the chip too fast, and the contact force is too large, which will cause the chip to be damaged due to excessive pressing. And...
