Bondjet BJ985 – Battery Bonder

Fully Automatic Heavy Wire Wedge Bonder with a large working area

Bondjets BJ985 belongs to the new generation of ultrasonic wedge-wedge bonders developed for the fully automated processing of a wide range of large-sized substrates, chips, automotive applications (e.g. batteries) and other materials.  It can be used as a fully automatic machine or operated manually.

Hesse offers the only available solution on the market of handling wires from 50 µm up to 600 µm** with only one bondhead.

Hesse GmbH, as technology leader, has designed the only heavy wire bondhead with a non destructive pulltest and a unique transducer integrated sensor for 100 % quality monitoring in real time.
A bondhead change from aluminium to copper can be realized within minutes. In addition to a standard configuration Hesse off ers automation concepts individually adapted for every application.
