Publish Time: 2024-12-16
In the field of semiconductor manufacturing, die bonding machines face the challenge of welding chips of various sizes and types, and their strong adaptability has become a key factor in promoting the development of the industry.
The precision mechanical structure system of the die bonding machine is the basis for its adaptation to different chips. The clever design lies in the high adjustability of key components. For example, the travel range of the robot arm can be precisely adjusted by the advanced servo motor control system. Whether it is a tiny mobile phone chip, which may be only a few millimeters in size, or a large server chip with a side length of several centimeters, the robot arm can accurately locate the welding point of the chip. Moreover, the clamping device at the end of the robot arm adopts a flexible adaptive design, which can automatically adjust the clamping force and contact area according to the shape and size of the chip, ensuring that the chip will not be damaged during the process of picking and placing the chip, and stable and reliable operation can be guaranteed.
For different types of chips, such as traditional silicon-based chips and emerging compound semiconductor chips (silicon carbide, gallium nitride, etc.), the die bonding machine also has excellent coping strategies. At the software level, it has a rich chip database built in, which stores information such as the material properties and welding process parameters of various chips. When facing different types of chips, the operator only needs to select the corresponding chip model in the control system, and the welding machine can automatically call the appropriate welding program. For example, for silicon carbide chips with good thermal conductivity, the welding machine can adjust the welding temperature and time according to its characteristics to ensure the welding quality while giving full play to the performance advantages of the chip.
In terms of hardware, the heating module and welding head material of the die bonding machine are also diverse and switchable. According to the requirements of different chips for welding energy and temperature, the heating module can flexibly switch between different powers and heating methods (such as heat conduction, laser heating, etc.). The material of the welding head is selected according to the hardness and wear resistance of the chip to ensure that the welding head can maintain a good working condition during the long-term welding process and can adapt to the welding requirements of different chip surfaces.
In addition, the visual recognition system of the die bonding machine also plays an important role in adapting to different chips. High-resolution cameras can quickly and accurately identify chip outlines, pin positions and other information of different sizes and shapes, and transmit these data to the motion control system, thereby achieving precise positioning of the chip and optimized planning of the welding path. Whether it is a high-density integrated circuit with extremely small chip pin spacing or a customized chip with a relatively special pin layout, the visual recognition system can effectively respond to ensure the accuracy of welding.
In summary, the die bonding machine has demonstrated extremely strong adaptability to chips of different sizes and types with the adjustability of its precision mechanical structure, the coordinated adaptability of software and hardware, and the precise assistance of the visual recognition system, providing a solid technical guarantee for the diversified development of the semiconductor industry.
