BLADE PRECONDITIONING PROCEDURE
Our Dicing Blades are pre-dressed, therefore a long extensive procedure is not necessary. However, we recommend the following to retrue and condition every time it is first mounted on the saw spindle to improve the quality of cuts and to extend blade life.
Hub Blades - Can be dressed either dummy silicon wafer or dressing board.
In Silicon Wafer
4,5 or 9 Micron grit size blade, cut
at fixed table speed = 10mm/sec (or 0.39"/sec) and according to chart below.
| Z-index* | Equivalent Dept of Cut |
No. of cuts |
| 0.012" 0.010" 0.008" 0.007" 0.006" 0.005" |
0.015" 0.017" 0.019" 0.020" 0.021" cut thru |

* Based on wafer thickness = 0.021" mounted on top.
2 Micron grit size blade, cut as above but at fixed table speed = 5mm/sec (or 0.197"sec.)
Dressing Board
4,5 or 9 Micron grit size blade, cut
according to chart below with depth of cut = blade length - 0.005"
