Diamond wire for silicon bricking and cropping/slicng

Diamond wire enables  bricking and cropping output increased. Diamond wire is suitable to convert existing slurry saws with process support. 1. Reduced cut times 2. Cleaner and easier cooperation 3. Lower cost of ownership than comparable slurry-based systems 4. Increased productivity 5. Remarkable cutting accuracy 6. Stable, repeatable process 7. Potential kerf recycling Products Specifications:  Diameter（mm） Core Wire（mm） Tolerance（±mm） Break Tension（N） Spool Wire Tension at Winding  (N)  Pitch（mm） 0.35（crinkle） 0.25 0.02 ≥150 15±1 0.5-0.6 0.35 0.25 0.02 ≥160 15±1 0.5-0.6 0.37 0.27 0.02 ≥190 15±1 0.5-0.6 Applied Case:  Machine Manufacturer Machine Model HCT HCT squarer DM Shanghai Nissin NWSS-125G Meyer Burger BM850 Diamond wire cutting results： Capacity Diamond Wire Cutting time per ingot 2:35 hours Downtime between cuts: 0:20 hours Precision Surface roughness ra    <     3     μm Tolerance ± 0.25 mm (³) Parallelity / flatness 0.25 mm TTV 0.5 mm Perpendicularity 90° ± 0.2° * Brickmaster BM 850 Bricking comparison: Slurry versus Diamond Wire Feature Slurry Diamond Wire Maximum Feed Rate: 0.8 mm/min 2.0 - 3 mm/min* Cutting time - 250 mm ingot height 6.4 hours (400 minutes) 2.6 hours (150 minutes) Capacity - G5 ingot, 156 x 156, 25 bricks/ingot 3.3 cuts/day ; 92 bricks/day 8.3 cuts/day ; 207 bricks/day Capacity - 125 x 125 mm 7800 wafers/day 16100 wafers/day Heat Induction 40° - 60° C < 20° C *dependent on ingot quality
