Fully Automatic Heavy Wire Wedge Bonder


Product Description

The Bondjet BJ955 and BJ959 belong to the new generation of ultrasonic wedge-wedge bonders developed for the fully automated processing of a wide range of large-sized substrates, chips and other materials. The systems can be used as fully automatic machines or operated manually. Capable of handling wire diameters from 50 μm up to 600 μm, these systems are incredibly flexible. Outstanding features include high speed and large bonding area. A change from aluminium to copper can be realized within minutes. Hesse GmbH 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. Advanced features available on the Bondjet BJ955 and BJ959 are designed to meet your present and future requirements and greatly enhance productivity. In addition to a standard configuration Hesse offers automation concepts individually adapted for every application.
