  4. Company Technology Arc-evaporation deposition is normally used to apply wear-resistant coatings to machine tools. However, the substantial distribution of macroparticles associated with this process limits the film quality. To solve this problem, Nanofilm Technologies International Pte Ltd has developed a revolutionary new version of FCVA deposition technology. Our patented technology can produce high quality Tetrahedral Amorphous Carbon (ta-C) coatings to satisfy even the most stringent requirements. During deposition, the surface temperature of the substrate is generally below 70 °C, which makes coating on plastic possible too.

  5. Film Qualities Film by Competitor's Cathodic Arc Technology*Under optical microscope (X200) Film by Nanofilm's Double Bend FCVA Technology*Under optical microscope (X200) Company name

  6. Classification Sp3 bound Sp2 bound FCVA technology can make The ta-C contains up to 88% of sp3 bonds Company name

  7. PCB Drills What is ta-C film provide: What are customer benefits : - Super high hardness  (3000~6000HB). - Wear and scratch resistance. - Excellent adhesion to surface. - Extremely smooth coating surface. - Better release performance. - Corrosion resistance. • Diameter of plated through hole is  getting smaller • The number of through holes is    getting higher per square meter • Prolong the lifespan by 2 times on    the flexible board, 4 times on the    BAG board • Obviously avoid the fracture (0.1mm    PCB drills) • Excellent smooth surface of the    through hole • Excellent CPK Performance • Longer tools maintenance cycle • Less Manufacturing Downtime. • Lower production cost

  8. PCB Drills Drilling of Double Sided Cu Clad/Fiber Reinforced Substrate: PCB Drills Conclusion: ta-C Coating Extends Lifespan of Drill Bits by 3 Folds

  9. PCB Drills Drilling of 16 Layers Cu Clad/Fiber Reinforced Substrate: PCB Drills Conclusion: ta-C Coating Achieves Cost Reduction of 41%

  11. Endmills What is ta-C film provide: What are customer benefits : - Super high hardness  (3000~6000HB). - Wear and scratch resistance. - Excellent adhesion to surface. - Extremely smooth coating surface. - Better release performance. - Corrosion resistance. • Excellent performance in some sticky    metals cutting (anti-sticky) • Excellent smooth surface after    cutting • Excellent CPK performance • Higher cutting speed • Longer tools maintenance cycle • Less Manufacturing Downtime. • Lower production cost • Longer tool life

  12. Endmills Endmills Test:

  13. Endmills Result: - After 2 hours of milling with uncoated Carbide End Mill • Severe wear is observed • Texture line on surface is damaged • Surface becomes rough With Uncoated End Mill Surface Morphology of Al Block - After 4 hours of milling with ta-C coated Carbide End Mill • Minimum wear • Texture line on surface remains intact • Surface is still smooth With Ta-C coated End Mill Surface Morphology of Al Block

  14. Endmills Conclusion: • ta-C coating helps to prolong lifespan of end mills significantly and improve finished milling surface • ta-C coated cutters are capable of performing dry cutting operations.

  15. Insert Insert: - Al Cutting performance on Insert

  16. Mold- Plastic Injection What is ta-C film provide: What are customer benefits : - Super high hardness. - Wear and scratch resistance. - Extremely smooth coating surface. - Better release performance. - Corrosion resistance. • Longer tool life • Excellent anti-sticky performance • Excellent anti-rust performance • Longer mold maintenance cycle • Better plastic parts quality • Lower production cost • Mirror surface maintained Example.

  18. Mold- Glass Lens / CD - DVD What is ta-C film provide: What are customer benefits : - Super high hardness. - Wear and scratch resistance. - Extremely smooth coating surface. - Better release performance. - Corrosion resistance. • Longer tool life • Excellent anti-sticky performance • Excellent anti-rust performance • Longer mold maintenance cycle • Better plastic parts quality • Lower production cost • Mirror surface maintained Glass Lens Mold CD / DVD Mold

  19. Mold- Glass Lens / CD - DVD • TAC-ON coated mirror molds experience lesser wear • Better adhesion strength on mold surface as compared to conventional DLC coating. • Mold release and fillings are easier and smoother due to the low surface energy of TAC-ON coated mirror mold.
