¡¡¡¡With the vigorous development of the semiconductor industry, more and more need to be more efficient and more stable structure to meet. The appearance of the linear motor first solves the speed and precision of the old type of servo motor screw. And higher dynamic response characteristics and more efficient motor design will be more and more demanding on the linear motor.
¡¡¡¡The most commonly used linear motor types are flat-panel linear motors, U-slot linear motors and cylindrical linear motors. Cylindrical linear motor that is voice coil motor. The voice coil motor has the advantages of simple structure, fast response speed, high sensitivity, good followability, good sealing property, good pollution, strong adaptability, stable and reliable operation, long life and so on. Therefore, in the field of semiconductor related devices, The use of such motors. Voice coil motor application market prospects are very broad. This article with Mao straight motor with you to understand the field of semiconductor voice coil motor applications.
¡¡¡¡Patch application
¡¡¡¡The operation of the voice coil motor in the patch process is mainly three parts: pick up, rotate and place. Pick up and rotate the action only need to move the target location requirements, voice coil motor pick up, rotate the two movements are repeated movement. Chip placement is the most critical part of the entire patch process. To ensure the reliability of the patch, the link not only requires high-precision position control, but also the voice coil motor linear shaft output force control, that is, force / bit mixing control. Specific to the voice coil motor control mode, that is, how to efficiently and securely realize the voice coil motor soft landing. , The latter can effectively realize the soft landing control of the voice coil motor, and it is more advantageous in terms of parameter setting, program preparation and motion trajectory observation.
¡¡¡¡Lead connector
¡¡¡¡The device of the lead connector associated with the semiconductor manufacturing apparatus is generally used on the Z-axis mechanism and the XY table mechanism. Z-axis mechanism, is relative to the XY table on the IC chip, with metal wire connecting the electrode and lead frame and up and down movement of the body. The XY table mechanism is a mechanism for moving the IC chip electrode and the lead frame's table by changing the connection position.
¡¡¡¡Effective buffer
¡¡¡¡In order to ensure the machining accuracy in the semiconductor-related device, the vibration of the foundation on which the device is placed and the vibration generated by the drive machine provided on the device must be suppressed. The original is the use of spring and fluid passive or active vibration suppression, because the voice coil motor structure is simple, good response characteristics, but also to detect the vibration can achieve the role of offset operation. This effective shock absorber is very suitable, and thus get a positive promotion.
¡¡¡¡Kunshan Tongmao Electronics Co., Ltd., is a set of linear motor technology research and development, linear motor, voice coil motor and precision linear platform to create and sell as one of the manufacturers. With the peak of the standard voice coil motor thrust can reach 5000N, stroke can reach 300mm, swing type voice coil motor peak torque of 50N.M, swing angle greater than 120 ¡ã.
