Case Study: Enhancing Wet Cleaning Efficiency
Application: Automated Wet Process Systems
A global tier-1 equipment supplier specializing in high-performance wet-process automation systems for the semiconductor industry.
Traditional pipeline systems under highly corrosive HF (Hydrofluoric Acid) and strong oxidizing chemicals had a short lifespan of only 6 months. Furthermore, there was a continuous risk of metallic trace element leaching, significantly impacting wafer yield rate.
Frequent Downtime & Ion Contamination
Completely engineered and upgraded the entire pipeline with QEEHUA Ultra-pure high density PVDF piping system integrated with zero-dead-leg diaphragm valves, ensuring a smooth, crevice-free inner surface.
Crevice-Free Flow & Complete Chemical Inertness
Continuous stable operation exceeding 18 months in harsh environment.
Verified by strict 3rd-party ultra-pure water extraction tests.
Pain Points & Strategic Solutions
Contamination Control
Inferior materials leach impurities into chemicals.
Porcelain-white mirror-finish PP boards for visual cleanliness and zero precipitation.
ESD Risk Management
Anti-static 106-1011 Ω and conductive options for safe wafer handling.
