Dicing sapphire
WebDicing is a process for cutting and making grooves on board-type workpieces approx. 10 mm thick using dicing blades. Dicing blades are abrasive blades that use synthetic diamond as the abrasive grit. The outer diameter of the dicing blade is approx. 50 mm and thickness is approx. 0.01 - 0.5 mm. WebIn stealth dicing, a laser beam that transmits through the wafer is focused beneath the surface, creating a row of perforations in a “stealth dicing” (SD) layer. ... The technique also may find use on other materials, including …
