In CCD automatic alignment exposure machines, the precision of alignment is critical for ensuring accurate exposure of photomasks to substrates. The YK-XXY200PL-S1-1255 platform offers a repetitive positioning accuracy of ±3μm, which is essential for achieving high-precision alignment. This accuracy ensures that each exposure cycle is consistently aligned, reducing errors and improving the overall quality of the exposure process. The platform’s ±10mm stroke and ±5.5° rotation angle provide the flexibility needed to accommodate various substrate sizes and shapes, ensuring versatile application in different production scenarios.

The stability of the alignment platform directly impacts the exposure quality. The YK-XXY200PL-S1-1255 platform features a self-made integrated bearing steel sliding block, which enhances its stability and reduces mechanical vibrations. With a flatness of ±0.025mm and motion parallelism of ±0.03mm, the platform ensures smooth and accurate movement during the alignment process. This high level of mechanical stability minimizes alignment errors and contributes to the reliability of the exposure machine.

In high-demand environments such as CCD automatic alignment exposure, the platform must handle significant loads while maintaining performance. The YK-XXY200PL-S1-1255 platform supports a horizontal load capacity of up to 30kg, making it suitable for various types of photomasks and substrates. Constructed from aluminum alloy and treated with black anodization, the platform is not only durable but also resistant to corrosion and wear, ensuring long-term reliability in demanding conditions.

For precise control of the alignment and exposure process, the platform integrates an Inovance 100W motor (provided by the customer) and a SL-205NA-W sensor (AKUSENSE). The motor allows for accurate and smooth adjustments, while the sensor provides real-time feedback on the platform’s position. This combination enables the CCD system to make automatic corrections based on sensor data, ensuring precise alignment and reducing the likelihood of exposure errors. The CS-19X20.7-8X6 coupling further enhances the reliability of the system by ensuring efficient power transmission between components.
