Company Technology

Established in May 1999, Nanofilm Technologies International Pte Ltd is an internationally recognized authority in the field of Filtered Cathodic Vacuum Arc (FCVA) Technology. Our FCVA coating technology represents a significant advancement in thin film deposition, and is the result of 7 years ground-breaking work by a team of researchers led by Associate Professor Dr. Shi Xu, the Chairman and co-founder of Nanofilm.

Our FCVA Technology has received numerous academic awards, including the prestigious Singapore Innovation Award & National Technology Award conferred by the National Science & Technology Board of Singapore. Nanofilm has a portfolio of patents covering various areas of FCVA Technology and its applications.

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.

PCB Drills

- 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
