  • Process secured adjustment of the wire feed elements
  • Camera image (5 orientations) can be stored in logbook after each tool change
  • Guaranteed repeatability set up
Process integrated Quality Control system PiQC
 

 
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
Software Options

Automation

 

 

 

 

 

 

The precise and safe handling of the products in and out of the production machine plays a significant role in controlling the product quality, yield and efficiency of the production equipment. For this reason Hesse GmbH is offering automation concepts individually adapted for every application.

The portfolio of automation components for our machines consists of the following groups:

  • Indexer / Transport system
  • Bonding Station
  • Magazine Lifts
  • Visualization
  • MES Interface

All our machines are suitable for integration into production lines. This also applies to indexers and magazine lifts, which generally communicate to neighbouring systems by SMEMA interface. The customer specific special solutions which differ from the standard, have lead to some extraordinary optional features, such as:

  • Indexer with automatic rail width adjustment
  • Indexer with tilt function for bonding 3-dimensional MID’s
  • Integrated barcode scanner for automatic program selection
  • Indexer with 2 or 3 rails for parallel AUER boat processing
