Hesse Mechatronics Automatic Bonders

Bondjet BJ935/BJ939

Fully Automatic Heavy Wire Bonder

The Bondjet BJ935/939 is an ultrasonic wedge-wedge bonder developed for the fully automated processing of a wide range of substrates, chips and other materials. The system can be used as a fully automatic machine or operated manually.

The Hesse GmbH as technology leader has designed the only heavy wire bondhead with non destructive pull test and a unique transducer integrated sensor for 100% quality monitoring in real-time. Further outstanding features are high speed and the largest bonding area. Advanced features available on Bondjet BJ935/939 are designed to meet your present and future requirements and greatly enhance productivity.

Features

Advanced Features and Process Advantages

  • 50 µm – 600 µm bondhead for Al, Cu, AlCu
  • Precisely programmable bondforce actuator: wire 2500 cN adjustable, Ribbon/Cu 5000 cN adjustable
  • Cutting methods:
    • Active Cutting: repeatable, precise, programmable cutting depth
    • Air Cut: No impact on surface, e.g. for highly sensitive chips because of „touch-free“ cutting
    • Passive Cutting
  • E-Box: patented solution for optimized tool change and programmable alignment marks for guide, cutter and bond wedge

Flexibility

  • Working area BJ935: 254 mm x 244 mm (10″ x 9.6″)
  • Working area BJ939: 350 mm x 560 mm (13.8″ x 22.0″)
  • Flexible use of the large working area, e.g. vacuum-clamping of up to six 5″ x 7″ standard DCBs
  • Maximization of throughput by automation with two or more parallel lanes

Quality

  • Continuous real time monitoring of wire deformation, transducer current and frequency within programmable control limits
  • Process integrated Quality Control PiQC – integrated in Hesse Mechatronics‘ Workbench: detection of further parameters by additional sensor system(e.g. friction) for 100% quality monitoring in real time (patented)
  • Remote pull function on PiQC threshold value for optimized cycle time; up to 30 % safe on equipment
  • Integrated, non-destructive pulltest for wire and ribbon
  • PBS200 – server for central data management
  • BDE, traceability – in PBS200 integrated XML interface or customized implementation
  • SECS/GEM – in PBS200 integrated standardized server connection for automation and communication
  • MES – interface to Manufacturing Execution Systems, integrated or in PBS200 realized, customized implementation

Speed

  • Highest UPH due to linear motors for bonder and indexer
