半導体露光装置向け事例：真空プロセスモジュール用クリーンシール
課題
露光装置サブシステムで、真空引きと熱サイクル時にパーティクル変動とシール性能のドリフトが発生し、保守枠の圧迫が続いていました。
ソリューション
RubberQ はゲート部と真空搬送部向けに半導体グレード FFKM シールを設計し、低アウトガス配合、バリ管理成形、ロット追跡を組み合わせてクリーン組立要件に合わせました。
実装成果
- →真空・ベークの繰り返し条件でもシール挙動を安定化し、計画外交換を抑制。
- →よりクリーンなシール面と工程管理で、保守時のパーティクルリスクを低減。
- →ロット追跡と受入品質の一貫性により、保守計画の見通しを改善。

Surface Blooming: Is that White Powder on your Rubber Part a Defect?

ソリューション
Surface Blooming: Is that White Powder on your Rubber Part a Defect?
実装成果
- →Primary Cause : Excess sulfur or stearic acid in the compound migrates to the surface during post-cure cooling.
- →Molecular Mechanism : Low solubility of curatives in EPDM at room temperature forces phase separation. The issue worsens with high-temperature cycling.
- →Solution : Reformulate with peroxide curing (no sulfur) or optimize accelerator-to-sulfur ratios. RubberQ’s in-house compounding adjusts curative dispersion at the 0.5-1.2 phr level.
