Bondjet BJ939

The Hesse 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 only on

BONDJET BJ939 are designed to meet your present and

future requirements and greatly enhance productivity.

New Benchmark for Heavy Wire Bonders

Advanced Features and Process Advantages

»• E-Box: patented solution for optimized tool change and

programmable alignment marks for guide, cutter and

bond wedge

Maintenance-free solid state joints

Closed loop force control programmable,

wire: from 0 cN up to 1400 cN

ribbon: from 0 cN up to 4000 cN

»• Touchdown and deformation sensor without signal

delay

Active cutting bondhead

•» Accurate positioning of the cutter and therefore

repeatable precise and programmable cutting depth

Better access into tight packages as no pusher is

needed

Extended cutter lifetime
