Benefits and Features
Advanced features and process advantages

Telescopic table for manual Loading
- 50 μm – 600 μm** bondhead for Al, Cu, AlCu (2 mil – 24 mil)
- Improved wire handling: short distance between bondhead and spool
- Optimized pattern recognition: image capture with new digital image processing and flash
- Hesse Assist Tools (option):
- E-Box: patented solution for optimized tool change and programmable alignment marks for cutter, wire guide and bond wedge
- Automated bondforce calibration; a load cell prevents operating error and ensures robust processes
- Innovative bondtool detection
- Wire spool detection
- Automated bondtool calibration without wedge gauge
- Precisely programmable bondforce actuator
- Loop generator for individual loops
- Wear-free components with Piezo technology
- Maintenance-free solid state joints
- Pre-setting of bondheads via EEPROM
Flexibility
- Working area:
BJ985: 370 mm x 870 mm - Flexible use of the large working area, e.g. vacuum clamping of several 5″ x 7″ standard DCBs
- Maximization of throughput by automation (two/more parallel lanes
Quality

Heavy Wire Bondhead
- Continuous real time monitoring of wire deformation, transducer current and frequency within programmable control limits
- Process integrated Quality Control PiQC: detection of further parameters by additional sensor system (e.g. friction) for 100 % quality monitoring in real time (patented); as option
- Remote pull function on PiQC threshold value for optimized cycle time; up to 30 % save on equipment
- Integrated, non destructive pulltest for wire and ribbon
Heavy wire bondheads
- Heavy wire and ribbon bondheads for Al, Cu and AlCu
- An intelligent bondhead connecting system with integrated memory stores all calibration data and enables bondhead replacement in a few minutes
- Wire clamp for loop shape control is standard on all bondheads; optionally equipped with non destructive pulltest
