Metal bond Diamond Dicing Blades
1A8 Ultra- Thin metal diamond dicing blade
Thickness of dicing blade: 0.08mm – 2mm
Application: cutting / scribing electronic parts, optical devices, semiconductor packages, BGA, CSP, ceramic, glass, crystal, etc
Product Details
Metal bond blades are using sintered metal powder as the bonding agent, have the excellent ability to hold its shape for a longer period of time, high rigidity minimized wavy and slant cutting, able to control diamond concentration to achieve cutting quality, excellent rigidity and cut quality.
How to selection of the correct types of dicing blades to cut materials
* Binder of resin bond (soft strength) dicing blade, scribing hard and brittle material
* Binder of metal bond (medium strength) dicing blade
* Binder of electroplated bond (hard bond), scribing softer material
Applications of metal diamond dicing blade
Scribing electronic parts, optical devices, semiconductor packages, BGA, CSP, ceramic, glass, quartz, crystal, etc
