■We perform dimension measurement and rank classification using a high-pixel
camera.
It can be expected to improve the yield such as improving the printing
misalignment.Slit classification is also possible.
■Since the substrate surface is excellent in smoothness and there are few voids (holes on the substrate surface), it is also used in chip resistors for thin film applications.
■We can provide finishing with minimal burrs.
■We can handle the design, manufacturing, and repair of molds in-house.
