1. Patent end block structure with waterway 100% filled with cold water, ensure cooling of bombarding area (especially important for roll2roll web coating or sputtering upwards from bottom) thereinafter, higher process power/lower substrate thermal effect - nearly 100% water drainage during target exchange, no water leakage to vacuum sealing.
2. Mechanical Shaft Seal is specially designed with specialty structure and compound materials, stable rotation significantly improves process stability.
3. Design of unique conductivity structure and compound material, end block overall resistance down to 0.6Ω, given a stable impedance with no jump, it works at high current flow, stable coating process.
4. Optimized end block structure per requirements, with above 80L/min water flow rate (water I/O pressure difference at 0.3Mpa, allow higher sputtering power).
