Bondjet BJ955 / BJ959 / BJ985 – Fully Automatic Heavy Wire Wedge Bonder

Bondjet BJ955/959 and Bondjet BJ985 belong to the new generation of ultrasonic wedge-wedge bonders developed for the fully automated processing of a wide range of large-sized substrates, chips, automotive applications (e.g. batteries) and other puposes.
The systems can be used as a fully automatic machine or operated manually. Hesse offers the only available solution on the market of handling wires from 50 μm up to 600 μm** with only one bondhead.
The Heavy Wire Bonder are characterized by several features:

  • Optimized pattern recognition (PR)
  • Software features for the growing demand of connectivity andindustry 4.0 (e.g. Hesse Bonder Network, remote control of PR,improved MES integration, …)
  • Hesse Assist Tools: load cell, bondtool and wire spool detection, tool calibration without wedge gauge for operator independency

Outstanding features are high speed and the large working areas. A bondhead change from aluminium to copper can be realized within minutes. Hesse GmbH, as technology leader, has designed the only heavy wire bondhead with a non destructive pulltest and a unique transducer integrated sensor for 100 % quality monitoring in real time. In addition to a standard configuration Hesse offers automation concepts individually

  • 50 μm – 600 μm** bondhead for Al, Cu, AlCu (2 mil – 24 mil)
  • Large working areas up to 370 mm x 870 mm
  • High drive through in the Bondjet BJ985
  • Improved wire handling: short distance between bondhead and spool
  • Optimized pattern recognition: image capture with new digital imageprocessing and flash
  • Hesse Assist Tools (option):
    • E-Box: visualization 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 individualized loops
  • Wear-free components with Piezo technology
  • Maintenance-free solid state joints
  • Pre-setting of bondheads via EEPROM

Automotive Module

Flexibility

  • 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

  • Continuous, real time monitoring of wire deformation, transducer current and frequency within programmable control limits
  • Process integrated Quality Control PiQC: detection of further parameters, e.g. friction behavior, by additional sensor system 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
