XYT™ Silicon Carbide Lapping Film

Silicon Carbide Lapping Film

Overview:

Silicon Carbide (SiC) Lapping Film is a precision-coated abrasive film designed for fine finishing, polishing, and material removal in various high-precision applications. It consists of micron-graded silicon carbide abrasive particles bonded to a uniform polyester film backing, ensuring consistent and repeatable performance.

Features:

• High Cutting Efficiency – Silicon carbide abrasives offer fast cutting action with minimal pressure.
• Consistent Finish – The precision coating ensures uniformity, delivering reliable and repeatable polishing results.
• Durability – Tough polyester backing enhances film longevity and performance.
• Available in Various Grades – Ranges from coarse to ultra-fine grit sizes (e.g., 0.3µm – 30µm) for different applications.
• Versatile Forms – Available in sheets, discs, tapes, rolls, and custom die-cut shapes with or without PSA backing.

1. Grit Sizes and Their Applications

2. Common Applications

1) Fiber Optic Connector Polishing

• Used in FC, SC, ST, LC, MU, MPO, MTP, and MTRJ connector polishing.
• Provides precise end-face geometry with minimal surface defects.

2) Precision Optics & Glass Polishing

• Applied in lens, optical crystal, and precision glass component finishing.
• Ensures clarity and defect-free surfaces for high-performance optics.

3) Semiconductor & Electronics Industry

• Used for wafer polishing, thin-film surface finishing, and microelectronic components.
• Enables high-flatness and low-defect finishes.

4) Metallography & Hard Materials Polishing

• Ideal for polishing ceramics, tungsten carbide, hardened metals, and composites.
• Used in research labs and material analysis processes.

5) Automotive & Aerospace Industries

• Used in superfinishing processes for precision engine and transmission components.
• Provides low-friction, high-performance finishes on metal surfaces.

3. Common Polishing Process

Step 1: Surface Preparation (Coarse Grinding)

• Use 30µm – 15µm SiC lapping film to remove surface irregularities and achieve uniform flatness.

Step 2: Intermediate Polishing

• Use 12µm – 6µm grit to refine scratches and prepare the surface for fine finishing.
• Maintain even pressure and use appropriate lubrication (water or slurry if required).

Step 3: Fine Polishing

• Apply 3µm – 1µm SiC lapping film for enhanced smoothness and scratch reduction.
• Ensure clean work conditions to avoid contamination.

Step 4: Final Polishing (Mirror Finish)

• Use 0.5µm – 0.3µm grit for ultra-smooth finishing.
• Often combined with slurry or polishing solutions for maximum effectiveness.
