Full Auto AF Material Magnetic Sputtering film coating equipment Anti Fingerprint Sputter coating machine

AF Magnetic Sputtering Coater (anti-fingerprint) applies the advanced coating technology of Kerun Vacuum's unique ion source assistance, magnetic intermediate frequency reactive sputtering and evaporation coating process, which significantly improves the quality of AF film layer. The products from the AF magnetic sputtering coate can meet the European CE standard.

Detailed Introduction to AS AF Film PVD Magnetron Sputtering Coating Machine

1. Working Principle

The machine integrates Physical Vapor Deposition (PVD) and magnetron sputtering technology to prepare films with both Anti-Scratch (AS) and Anti-Fingerprint (AF) functions. The core process is as follows:

• Vacuum Environment Establishment: The coating chamber is pumped to a high vacuum (10⁻³ ~ 10⁻⁵ Pa) to eliminate air molecules that interfere with film formation.
• Gas Ionization: Inert gas (usually argon, Ar) is introduced into the chamber. High-voltage electricity ionizes Ar into Ar⁺ ions and free electrons.
• Magnetic Field Confinement: A permanent magnet inside the target (coating material source) generates a strong magnetic field, which traps free electrons near the target surface. The confined electrons collide with more Ar atoms, increasing the ionization rate of Ar.
• Target Sputtering: Ar⁺ ions are accelerated by the electric field to bombard the target surface. The target atoms (or molecules) are knocked off and form a "particle flow" (sputtered particles).
• Film Deposition: Sputtered particles fly to the substrate (e.g., glass, metal, plastic) and deposit on its surface, forming a dense, uniform film.
• AS & AF Function Realization:
  • AS Performance: Select high-hardness targets (e.g., SiO₂, DLC diamond-like carbon, Al₂O₃) to ensure the film hardness reaches 6H ~ 9H (resistant to scratches from keys or sand).
  • AF Performance: Modify the film surface with fluorine-containing targets (e.g., CF₄-derived fluoropolymers) to reduce surface energy (≤ 20 mN/m), making water/oil droplets roll off easily and preventing fingerprint adhesion.

2. Core Features

2.1 Film Performance Advantages

• Dual-Function Integration: Simultaneously achieves high scratch resistance (AS) and long-lasting anti-fingerprint (AF) effects, avoiding the need for secondary coating.
• Superior Film Quality: The magnetron sputtering process produces films with high density (≥ 98% of the target’s theoretical density), strong substrate adhesion (cross-cut test ≥ 4B), and uniform thickness (error ≤ ±5%).
• Stable Durability: AF effect remains effective after 500+ times of friction (with 500g load) or 200+ times of alcohol wiping; AS performance does not degrade after 1000+ times of steel wool friction.

2.2 Equipment Technical Advantages

• Wide Substrate Adaptability: Compatible with flat/3D substrates of different materials (glass, aluminum alloy, PC, PET) and sizes (from 300×300mm to 1800×2400mm).
• Environmental Protection: No organic solvents (unlike wet coating), no waste liquid/gas emissions, complying with RoHS, REACH, and other international environmental standards.
• Intelligent Control: Equipped with PLC + touchscreen system, supporting automatic pressure control, target current regulation, and coating time setting; real-time monitoring of vacuum degree, temperature, and film thickness.
• High Efficiency: Adopts multi-target configuration (2 ~ 6 targets) and continuous conveyor belt (for sheet substrates) or planetary rotation (for 3D parts), achieving a coating speed of 0.5 ~ 3 m/min (adjustable by film thickness).

3. Selling Points (Market-Oriented Value)

3.1 Solve Customer Pain Points

• Eliminates the problem of "easy scratches + fingerprint contamination" for high-end products (e.g., mobile phone screens, automotive glass), improving product user experience and lifespan.
• Replaces traditional wet coating (low durability, environmental pollution) and evaporation coating (low film density), reducing post-coating repair rates by ≥ 30%.

3.2 Cost-Effectiveness

• Low Operating Cost: Target material utilization rate reaches 70% ~ 85% (higher than evaporation coating’s 30% ~ 50%), and vacuum system energy consumption is 20% lower than similar equipment.
• Mass Production Compatibility: Continuous coating design supports 24/7 operation, with a single machine’s daily output (for 5-inch mobile phone glass) up to 10,000 pieces.

3.3 Customization & Compliance

• Customizable film parameters: Adjust target types (e.g., SiO₂ + fluoropolymer for high-transparency AS AF; TiN + fluoropolymer for metallic AS AF) and film thickness (50 ~ 500 nm) to meet different industry needs.
• Meets international quality standards: Films pass salt spray test (48 hours), high-temperature and humidity test (85℃/85% RH, 1000 hours), and UV aging test (1000 hours).
