Description

A Bonder for manual or automatic bonding

The Bondjet BJ653, with its changeable bond heads, serves the wire bonding processes of wedge-wedge as well as ball-wedge and can handle fine wire, heavy wire and ribbon. The operating methods from manual to automatic bonding is particularly appropriate for the use in laboratories, in the development and for suppliers for validating their product quality.

BJ653 is ideal for product samples, pre-production prototypes or small volume production runs in proven and reliable Hesse quality. The Bondjet BJ653 is part of the new bonder generation and offers the same handling regarding operation and look & feel as the the fully automatic machines of Hesse. It is characterized by an open workspace, which achieves the same process result as in a fully automated production wire bonder.

The Bondjet BJ653 has a lower throughput than the other Bondjets but is the avenue to fully automatic wire bonding. The available bondheads for the BJ653 are identical to the bondheads for the Hesse production machines. This enables a targeted preparation of the production process on the Bondjet BJ653.

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
