Wafer packaging is a critical process in the semiconductor industry, where precise dosing and high-speed rotation are required to apply adhesives or encapsulants to semiconductor chips. A chip packaging dosing rotary table is a typical industrial automation component used for this process. These systems typically consist of a rotating platform, dosing unit, and a motion control system, with the gearbox playing a vital role in achieving smooth and accurate motion control.
Current trends in the industry include higher production speeds, smaller form factors for equipment, and the demand for consistent performance in cleanroom and high-temperature environments. However, several technical challenges hinder these developments:
- High precision and stability are required for micro-dosing operations, yet vibration and backlash from traditional gearboxes can lead to defects.
- Compact design is essential, but standard solutions often fail to fit the limited space due to their large footprint.
- Energy efficiency is increasingly important to reduce operational costs, especially with frequent start-stop cycles.
- Environmental compatibility is crucial in cleanroom and high-temperature environments, where contamination and thermal expansion must be minimized.
These challenges demand a high-performance, reliable, and compact gearbox solution capable of integrating seamlessly into the semiconductor packaging process.
In wafer packaging dosing rotary table systems, the gearbox is a core component. It must meet the following technical requirements to ensure the performance of the overall system:
- High torque density to handle the mechanical loads from multiple dosing heads.
- Low backlash and high positioning accuracy to ensure the correct adhesive dosage is applied without deviation.
- Fast response and high dynamic performance to adapt to variable speed and acceleration demands during operation.
- Compact and modular design to fit within limited installation spaces and reduce system complexity.
- High thermal resistance and cleanroom compatibility for use in controlled environments with strict contamination standards.
Additionally, the gearbox must have a long service life, with minimal maintenance required, to maintain high system availability and reduce downtime.
