DFG8020Fully Automatic Grinder

Grinder compatible with various workpiece shapes, including square workpieces

Capable of grinding square workpieces up to 390 mm

Provides fully automated transport, grinding, and spinner cleaning for square workpieces of up to 390 x 390 mm, including medium-sized 300 x 300 mm PLP substrates.

Supports advanced packaging processes

Enhanced handling capabilities, including transfer and vacuum chucking of warped package substrates, together with features such as end-point detection using an NCG (non-contact gauge)^* and in-process grinding wheel cleaning^*, enable the unit to meet the advanced processing requirements of advanced packaging.

* Available as a user-specified specification

Frame grinding specification (user-specified specification)

Grinding of workpieces mounted on a tape frame is supported. This enables processing of warped workpieces, simultaneous grinding of multiple workpieces, and processing of various workpiece sizes without the need for size conversion.

Parallel grinding specification (user-specified specification)

By changing the workflow, the unit supports parallel grinding, in which both processing spindles grind simultaneously, in addition to conventional rough grinding followed by fine grinding.

Workflow

The robot pick unloads a workpiece from the cassette.
Alignment takes place on the robot.
The T1 arm places the workpiece on the chuck tables.
The workpiece proceeds to Z1 for rough grinding.
The workpiece is transferred to the Z2 side.
The T2 arm places the workpiece on the chuck tables.
The workpiece proceeds to Z2 for fine grinding.
The T2 arm unloads the workpiece from the chuck tables and places it on the spinner table.
The robot pick returns the workpiece to cassette.
