80WT - Fully automatic dicing saw

FEATURES & BENEFITS

Fully automatic two spindles dicing saw, designed for precise step-cut Wettable QFN dicing. The 80wt performs perfect grooving operation with constant depth of cut and groove shape, on an uneven surface of the substrate.

CYCLE TIME INFORMATION

PROCESS

Feed Rate: 50 mm/sec
Mapping Feed Rate: 50 mm/sec
Mapping Rate: 5 Cuts

CYCLE TIME - 2 LEAD-FRAMES

Laser mapping total time: ~ 2 min
Dicing total time: about 5.5 min including alignment
Brush total time: 30 sec
Total time: about 8 min

BRUSH

Brush Cycles: 1 Feed Rate
During Brush: 10 mm/sec

CLEANING CYCLE TIME

Rinse : 500 rpm | 30 sec
Atomizing: 800 rpm | 60 sec
Air Drying: 1200 rpm | 30 sec

Since cleaning is done during dicing the cleaning time does not effect the total processing time
