Product DescriptionUltra-Thin Diamond Wire for Silicon Wafer SlicingRedefining wafer slicing economics, this China-manufactured diamond wire delivers sub-50μm kerf losses and zero crystal damage for monocrystalline silicon ingots. Engineered to replace slurry-based saws, it enables thinner wafers (120–160μm), higher yields, and zero hazardous waste.SpecificationWire Types: Electroplated (40–55μm) / Resin Bonded (60–70μm)Diamond Density: 80–220 grits/mm (adjustable)Line Speed: 15–25 m/s (servo-controlled)Tension Control: 18–25 N with ±0.2N stabilityCoolant: Water-based (neutral pH)Compatibility: 5–12″ ingots, n/p-type silicon, SiCWorking Principle"Monocrystalline diamond grit fractures silicon crystals via brittle-mode micro-fracturing along crystallographic planes using high-tension steel wire."Breakdown:Core Physics: Brittle-mode fracture (not plastic deformation)Cutting Edge: Monocrystalline diamond grit (3-8μm)Mechanism: Crystallographic plane cleavage (111 planes in Si)Execution: High-tension (18-25N) steel wire at 15-25m/sValidation: SEMI MF1832 wafer standards | ASME B74.20 abrasives classificationConcrete Cutting Wire SawGranite Mine/Marble-Specific Diamond Wire SawDiamond Wire Rope BeadsProduct Applications1. Photovoltaic Ingot Slicing: Produce 182mm/210mm solar wafers at <120μm thickness.2. Semiconductor Wafers: Precision slicing of 200mm/300mm Si and SiC boules.3. LED Substrates: Sapphire/GaN wafer dicing with <20μm chipping.4. Advanced R&D: Cutting 2D materials (graphene, TMDCs) for quantum devices.5. Recycling: Reclaim silicon from end-of-life PV panels.Product Advantages1. Slash Kerf Loss: 42μm wires extract 22% more wafers/ingot vs. 180μm slurry saws.2.Eliminate Sludge: Dry-cutting capable – saves $500K/year in waste treatment.3. Nano-Precision: <0.15μm Ra surface finish – reduces polishing costs by 40%.4. Speed Dominance: Cut 300mm wafers at 650mm/min (2.1× slurry saws).5. China Cost Scaling: 30% lower $/meter than Japanese competitors (DISCO, Nakayama).Company ProfileHUATAO GROUPHUATAO GROUP is a leading Chinese manufacturer of mining equipment with over 20 years of expertise.
