Bondjet BJ93X Description

Fully Automatic Heavy Wire Bonder

The Hesse & Knipps GmbH as technology leader has designed the only heavy wire bondhead with non destructive pull test and a unique transducer integrated sensor for 100% quality monitoring in real-time. Further outstanding features are high speed and the largest bonding area. Advanced features available on BONDJET BJ935 and BJ939 are designed to meet your present and future requirements and greatly enhance productivity.

• E-Box: patented solution for optimized tool change and programmable alignment marks for guide, cutter and bond wedge
