  5. Process integrated Quality Control system PiQC

    PiQC = Process integrated Quality Control

    The Hesse GmbH has implemented a new Process integrated Quality Control system (PiQC) that is unique to the global wire bonding market. A sensor integrated into the Transducer allows for the first time a multi-dimensional signal analysis of the bond process. PiQC calculates a bond quality index value in realtime, using significant signals from the wire-bonding process.

    Advantages for volume production

    • Inspection of every bond
    • No mechanical load of the bond connection
    • Product specific configuration of the quality control system

    Feedback from the process

    • Mechanical oscillation of the wedge
    • Friction at bond surface
    • Transducer current
    • Ultrasonic frequency progression
    • Wire deformation

    Quality statements by PiQC

    • PiQC calculates a quality index for each bond based on the actual feedback signal from the process
    • The signal related components of the quality index can be displayed graphically at any time

    Teach mode for reference data

    • Detailed automatic analysis of the welding process
    • Extraction of process-specific reference data
