Motorized Needles

Mechanically driven needles allow for synchronization of the actuation of the needles and movement of the die bonder tool. By controlling both the movements of the needles and bond head, a precise and constant amount of force can be applied to the die during the ejection process preventing damage to thin and fragile wafers.

Die Bond Software Integration

Integration with the advanced software of the die bonder lets the die ejector leverage the full capability of the VisionPilot® software; dealing with rotated wafers with ease and rejecting low quality die. The die bond system integration greatly expedites the ejection process with “look-ahead” functionality and automated wafer mapping based on ID.

Customizable Eject Heads

The eject heads can be customized with options for needle count, size, spacing, and arrangement options, as well as vacuum hole count, size, and location to fit any die or wafer type. Heads can be swapped easily for process changeovers that switch from one wafer design to another.

Diverse System Capabilities

Die ejection systems are offered in single, dual, quad, and hex configurations which can support up to 12" wafers depending on the configuration. The die ejection systems are able to handle both grip ring and film frame style wafers and can support ejection of dies down to 150?m in size.
