In advanced packaging, high-precision printing, and similar processes, defects caused by micro-fluidic control deviations result in average scrap rates as high as 3%-8% in related stages.

This figure is even more critical in stringent applications such as Micro LED mass transfer and biochip spotting, leading to substantial cost losses. According to a McKinsey manufacturing efficiency whitepaper, within electronics manufacturing, the cost of rectifying system-level failures is 50 to 100 times greater than intercepting defects on the production line.

To address this core challenge, the Quark Industrial Research Institute innovatively introduces the High-Speed Precision Micro-Fluidic Adaptive Control Platform. This shifts quality management from post-production discovery to real-time control, enhancing yield and efficiency from the source.

High Precision: Picoliter-Level Fluid Observation and Control

• Process Challenge: In applications like chip underfill, bioprinting, and high-precision printing, precise control over micro-droplets—including volume, morphology, landing position, and spread—is essential.

• Technical Solution: Designed specifically for high-precision micro-fluidic control, Quark's platform enables full-process observation and control of picoliter-level droplet generation, flight, and landing, achieving an accuracy of ±0.01 pL. It establishes a complete closed-loop control system for droplet morphology, ensuring consistency in landing precision and droplet form. This guarantees quality in ultra-precision processes for semiconductors, biomedicine, and next-generation displays.

Real-Time: Simultaneous Production, Monitoring, and Adjustment

• Process Challenge: In traditional dispensing/inkjet processes, quality inspection typically occurs after production. The inability to monitor fluid behavior in real-time directly leads to yield fluctuations.

• Technical Solution: The platform integrates ultra-high-speed fluid observation, enabling real-time monitoring of droplet behavior at millisecond scales during operation. With deep integration between observation data and the control system, it achieves real-time adaptive parameter adjustment, allowing for simultaneous dispensing, measuring, and tuning. This enables instant identification and automatic correction of minute process deviations, effectively intercepting defects and significantly reducing scrap rates.

Intelligent: Adaptive Regulation Powered by AI Data

• Process Challenge: Process parameter tuning heavily relies on operator experience, involving high trial-and-error costs, long durations (hours to days), and result variability, which severely impacts yield stability and new product introduction speed.

• Technical Solution: Quark's platform incorporates a vast process application database combined with AI algorithms for adaptive control tuning. Based on real-time fluid data and quality targets, it automatically matches optimal parameters, calibrates settings, and generates drive waveforms. This drastically reduces dependency on and time for manual debugging, ensures highly stable and consistent droplet output, improves yield stability, and accelerates new product ramp-up.

Comprehensive Capabilities:
The platform offers observation and control of adhesive/ink droplets, with inspection capabilities covering droplet velocity, volume, angle, and satellite droplets. Its analytical capabilities include real-time precise measurement with immediate feedback to the control system, scanning of drive conditions and environmental factors for testing, and evaluation of droplet quality and satellite droplet handling.

Furthermore, the platform features a modular design (host controller, compact drive-control unit, motion mechanism), allowing users to flexibly configure solutions tailored to specific process needs and quality objectives.

As a pivotal element in precision fluid real-time closed-loop control, the High-Speed Precision Micro-Fluidic Adaptive Control Platform embodies the Quark Industrial Research Institute's profound expertise in high-precision fluid control. Leveraging rapid advancements in AI technology, the integration of intelligent algorithms unlocks new potential for its extensive process knowledge base.
