Ultra-High Purity Bulk Liquid Chemical Delivery System (BCDS) for Maintaining Parts-Per-Trillion Purity in Manufacturing
In the world of advanced semiconductor and photovoltaic manufacturing, the journey of a process chemical begins with the Ultra-High Purity Bulk Liquid Chemical Delivery System (BCDS). This system serves as the primary “artery” of a facility, responsible for transporting large volumes of acids, solvents, and bases from bulk storage to the production floor without introducing a single microscopic contaminant.
To achieve and maintain Parts-Per-Trillion (ppt) purity, the BCDS is engineered using 316L electropolished stainless steel. This specialized material features a mirror-like 5Ra internal finish, which eliminates the microscopic “peaks and valleys” where particles could be trapped or metallic ions could leach into the fluid. Every weld and connection is designed to be “dead-space free,” ensuring that chemicals do not stagnate and degrade.
Managed by sophisticated PLC-controlled automation, a Jewellok-engineered BCDS provides a continuous, pulse-free flow. Safety is non-negotiable; the system integrates Nitrogen (N2) blanketing to prevent oxidation of sensitive chemicals and uses secondary containment with high-sensitivity leak detection. By providing a “zero-contamination” bridge between bulk supply and point-of-use modules, the BCDS ensures that the high-tech manufacturing process maintains 99.9% uptime and the highest possible product yield.
