What it is

The Towa SL 473 D 2 is a precision optics laser marker.^[1]^[2]

How it works

The Towa SL 473 D 2 includes acousto optic Q-switch drivers and a laser marker controller for pulse control and timing. The Towa SL 473 D 2 uses a NEC PC 9821 R 43 MZ for PC control.^[1]^[2]

Where it fits in the process flow

The Towa SL 473 D 2 is fitted for transfer handling and wafer marking on a Φ6' wafer size. The Towa SL 473 D 2 uses three-phase 200 V power at 40 A.^[1]^[2]

Applications

General reference — not yet source-verified

Laser markers in precision optics are used for part identification, traceability, and surface coding. Laser marking is also used where noncontact processing is preferred to reduce mechanical wear on the workpiece.
