Frequently Asked Questions
Technology
Can you support trial production?
Yes. First of all, we listen to customer inquiries, and we are working on prototypes and developments in order to realize what we can do. Smooth transition to mass production is also possible.
What materials can you handle?
Processing of metals such as CuW / Kv / Al / Ag / Mo / Cu, glass materials such as quartz, ceramics / sapphire and ultra-high purity silicon materials (single crystal / polycrystal) is possible.
What materials are used for heat sink products?
The table below shows the relationship between thermal conductivity and thermal expansion coefficient. In addition, Cu-AlN-Cu three-layer structure and Cu-Mo-Cu seven-layer structure are commercialized.
What kind of processing can you do?
Various processing as shown in the table below is possible for metal, glass, ceramic and silicon materials.
