E-Box
Adjustment tool for wire bonders
 
The E-Box of the Hesse GmbH is a patent-registered visualisation system for control supported, reproducible adjustments of bondhead elements or for graphical ball inspection. It includes a camera for optical displaying of wedge, cutter and wire guide as well as a graphical support for adjustment- and positioning control. E-Box allows significant time reduction for setting up the machine. Software enhanced optical adjustment system for wedge, cutter and wire guide / wire clamp.E-Box for Bonder – Advantages during Production

  • Better reproducibility of the adjustment depending attributes (e.g. loop forming) after change of wearing parts
  • Longer life time of wearing parts

Advantages for Bond Process

  • Graphical ball inspection in the ball-wedge mode
  • System for reproducible set-up of wedge, cutter and wire guide / wire clamp
  • Set-up without microscope
  • Free programmable, specified positions for bondhead elements
    • shown as limitation line
    • different views selectable (different sides, bottom, front etc.)
  • Minimizes time expenditure for set-up work, set-up control and readjustment
 
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
  • Manual heated workholder with adjustable height for maximum flexibility
  • Magazine lifts with capacity for multiple magazines
