Introduction of a case where a router adopted for printed circuit board cutting solved challenges.
The router for cutting printed circuit boards faced the challenge of achieving a long lifespan while maintaining dimensional accuracy. To address this, a carbon film that surpasses the conventional DLC film in hardness, smoothness, elasticity, and adhesion to the substrate was required, leading to the adoption of the 'ta-C film' produced by the FCVA method, which meets these performance requirements. It is also used in end mills (aluminum cutting tools) for processing aluminum die-cast back plates in the HDD industry. 【Application Example (Router for Cutting Printed Circuit Boards)】 ○ Significantly extended the machining length within dimensional accuracy ○ Enabled improvement of the process capability index Cpk For more details, please contact us or download the catalog.

Company information
Our development technology has obtained international patents and plays a significant role in society. The super DLC (hydrogen-free ta-C film) produced by the FCVA method is formed through a completely different process compared to DLC films generated by existing PVD and CVD methods. Additionally, there is a composite metal film called "Micc film" that excels in release properties between metals and plastics. Coating films produced by the FCVA method are currently being rapidly adopted in fields such as the hard disk industry, precision machinery industry, and semiconductor industry, and future expansion into the automotive industry, nanoimprint industry, and biomaterials field is anticipated.
