DAD 3220 Automatic Dicing

Machines in the dicing and grinding class are precision material-removal and singulation tools used on wafers, substrates, and other brittle engineered materials. They combine controlled motion, fixturing, and cutting or grinding elements to divide a processed workpiece into smaller units while limiting damage to surrounding structures.

An automatic dicing machine performs that separation with programmed handling and process control. Such systems are part of back-end semiconductor and precision-optics production, where clean cut quality, positional accuracy, and protection of finished features are important.

A dicing machine typically holds the workpiece on a chuck or similar support and brings a cutting or grinding tool into a controlled path across the material. Motion is managed in relation to alignment marks or known layout geometry so that streets, scribe lines, or designated separation zones are followed consistently.

In automatic systems, loading, positioning, cutting, and unloading are coordinated through machine controls. Coolant, debris management, and spindle or tool motion are used to reduce chipping, cracking, and contamination while the material is separated into discrete units.

This class of equipment is used near the end of wafer or substrate processing, after device fabrication, pattern transfer, or other front-end and midstream operations have been completed. It prepares the finished workpiece for die handling, packaging, assembly, or further module integration.

Machines of this class are used for singulating semiconductor wafers, compound semiconductor materials, advanced substrates, and precision optical or electronic materials. They are selected where controlled separation and edge quality matter for downstream assembly and device yield.
