The Katalyst uses a dual-bond head architecture with 6 nozzles per side, for a total of 12 nozzles. While the multi-nozzle system boosts throughput, it also places higher demands on nozzle-to-nozzle consistency. The system compensates for deviations across bond heads in real time through runtime automatic accuracy calibration, preventing nozzle-to-nozzle variation from affecting placement consistency. Automatic thermal drift compensation corrects for accuracy fluctuations caused by temperature changes during extended continuous operation.
The system integrates a look-down camera and a look-up camera for alignment. The look-down camera identifies substrate fiducials, while the look-up camera locates the die on the nozzle. The two cameras are automatically calibrated to align with each other. A post-bond vision verification system confirms bond placement, providing defect location data for downstream processes.

Production Line Adaptability
The Katalyst's automated tool exchange system supports simultaneous loading of a full tool set covering 5 applications. Tool changes are automatically verified via ID coding, and pick tool and place tool exchange is completed within 5 minutes, bringing overall application changeover time to within 20 to 30 minutes. Recipe loading is completed with a single software click in under 1 minute.
The system's factory interface is compatible with automated guided vehicles (AGV) and overhead transport (OHT) systems, supports material tracking and standard factory communication protocols, and can be integrated into fully automated Micro LED production lines.
Process Positioning in Micro LED Assembly
Within the Micro LED manufacturing flow, the Katalyst handles the bonding step that follows die transfer, forming the electrical and mechanical connections between already-positioned Micro LED dies and the driver substrate through a flip chip process. As pixel pitch shrinks below 10 μm, die size and alignment tolerance requirements tighten in tandem, making the placement system's accuracy headroom a critical yield variable. The Katalyst's 3 μm accuracy and multi-nozzle parallel operation correspond to the dual demands of precision and throughput in this step.
