DFD 641 Automatic Dicing

The Disco DFD 641 is an automatic dicing saw. The DFD 641 belongs to Disco's DFD family. The DFD 641 is categorized under dicing and grinding equipment.^[4][5][6]

Automatic dicing saws separate processed wafers into individual dies by cutting along scribe streets with a rotating blade. Dicing saws generally use staged motion, alignment, and workholding to position the wafer and execute repeated cuts across the substrate. Dicing equipment in this class is used after wafer fabrication, when patterned wafers must be singulated into individual chips or devices.

Dicing tools sit in back-end wafer processing after front-end device fabrication and after many wafer-level build steps are complete. Dicing commonly follows operations such as thinning, backgrinding, or wafer mounting when a wafer must be prepared for singulation. Dicing is followed by die handling, inspection, sorting, packaging, or assembly steps depending on the product flow.

Automatic dicing saws are used to singulate semiconductor wafers and other device substrates into individual units. Dicing equipment in this class is applied where precise separation of devices is required before downstream assembly or packaging. Typical use cases include integrated circuits, sensors, optoelectronic devices, and similar wafer-based components.
