Heavy Wire Bonder Bondjet BJ980

Bondjet BJ980

Fully Automatic Heavy Wire Wedge Bonder

especially for solar and battery applications

The ultrasonic wedge-wedge bonder Bondjet BJ980 serves, with its most flexible and largest working area of 700 mm x 1132 mm, the growing demands for large-sized substrates, especially for solar and battery applications.

The Bondjet BJ980 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; ribbons can be processed up to a size of 2000 µm x 400 µm**. Outstanding features are high speed and the largest bonding area in the industry. A change from aluminium to copper can be realized within minutes.

Hesse GmbH, as technology leader, has designed the only heavy wire bondhead with non-destructive pulltest and a unique transducer integrated sensor for 100% quality monitoring in real-time.
