Resin bonded blades have excellent cutting ability that help reduce chippingm fractures, can efficiency improve cut quality and efficiency on ductile and gummy materials such as QFNs and coppers and on hard and brittle materials such as glass and ceramic.
Applications of diamond dicing blade
Resin Bond Diamond Dicing Blades are suitable for cutting scribing glass (optical devices, fiber optics), quartz (optical splitters, saw devices), LiTa03 LiNb03 (devices), QFN （copper epoxy molding ), splitter, sapphire.
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
