Differences between FC and FCD for the semiconductor industry. Key points for selecting equipment components.

Vibration or strength? Differentiating between FC and FCD to solve designers' dilemmas. An explanation of optimal selection guidelines based on a comparison of material properties.

Are you experiencing a decrease in positioning accuracy due to the vibration of components not settling during high-speed operation in post-processing bonding and testing? As equipment becomes larger and more refined, the selection of materials for the base and columns is a crucial decision that affects equipment performance. ■ The decisive differences between FC250 (flake graphite) and FCD450 (spheroidal graphite) Vibration damping: FC250 has approximately three times the absorption capacity of FCD450, allowing vibrations to settle quickly. Stiffness and strength: FCD450 has a high Young's modulus of about 165 GPa, making it less prone to deformation compared to FC250 (about 90 GPa). Cost: FC250 excels in yield during manufacturing and has less distortion after processing compared to FCD450, making it easier to produce at a lower cost and with stable quality. Applications: FC is suitable for equipment bases, while FCD is appropriate for arms and other components where strength and stiffness are required. ■ Selection guidelines 1. If precision is a priority: Choose FC, which excels in vibration settling, to shorten stabilization time. 2. If addressing load and deformation: Pursue thin and lightweight components with high-strength FCD. The Hinode Group can provide optimal material proposals tailored to design challenges, such as "high-damping cast iron" and "mineral casting." 【For more details, download the catalog from the link below】
