<Process Example>
By using StayCool for QFN package cutting, the following benefits are realized.
- Improved blade life
- Increased processing speed
- Improved process quality
- Removal of copper powder adhering to the workpiece
･Blade life improvement + Feed speed increase
By employing StayCool, it is possible to lower CoO without excessive blade wear, even if the feed speed is increased.
Fig. 1 Blade wear comparison
･Process quality improvement
By adopting StayCool, the distance between the electrodes is thoroughly preserved because there is less electrode deformation.
