How to selection of the correct types of wafer 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

Dresser Board for dressing dicing blades

Dresser board is used for dressing and edged blade row, to increase sharpness, and reduce the chipping of the work piece, to reshape and perfect the blade edge to a flat edge
