Causes of Vibration in Equipment for the Semiconductor Industry and Countermeasures | Techniques for Reviewing Materials and Structures
Residual vibrations reduce yield. With mineral casting boasting ten times the damping capacity of cast iron, the stabilization time is dramatically shortened, achieving high precision.
Are you experiencing extended takt times due to "micro-vibrations" that do not settle after high-speed movement during bonding and inspection processes? The instability in positioning accuracy is fundamentally caused not only by a lack of rigidity but also by the low "damping" characteristics of the material itself. ■ Three Factors Causing Residual Vibration - Material: While steel has high rigidity, it has a weak ability to absorb vibration energy, resulting in residual oscillation. - Structure: An imbalance of rigidity and mass in the structure can lead to increased oscillation. ■ Solution: Mineral Casting Using polymer concrete made from resin and aggregates, it possesses an overwhelming vibration damping capacity approximately 10 times that of cast iron (FC250). By adopting it for vibration-sensitive components, the overall damping of the equipment can be improved. The "settling time," during which vibrations stabilize to a certain amplitude, can be reduced by about 60%. ■ Criteria for Re-evaluation 1. High Damping: Use mineral casting for areas where immediate cessation of oscillation is desired. 2. High Rigidity: In cases with space constraints where rigidity must also be maintained, consider a hybrid structure with cast iron. The Hinode Group provides comprehensive support from material development to structural analysis. We propose optimal structures based on the rigidity and vibration analysis of the current structure.
