E-Box
E-Box
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. 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
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
Process secured adjustment of wire feed elements (wedge, wire clamp, wire guide, cutter etc.)
Graphical supported, visual control of
wedge and wire guide position
distance between wedge and wire clamp
gap of wire clamp
wire pass
cutter respectively cutting position
Process integrated Quality Control system PiQC
PiQc
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
