Used MI Quantum

Mi Quantum is a flagship, AI-powered die sorter from Mi Equipment’s "Mi" series. Together with the Quantum Plus, it represents the high-end tier of this product line, primarily targeting the sorting of WLCSP (Wafer-Level Chip Scale Package) components used in smartphones, tablets, and wearable devices.

Throughput and Platform Architecture

The core selling point of the Mi Quantum is its market-leading throughput, exceeding 50,000 units per hour (UPH). This is achieved through a proprietary horizontal turret system that enables parallel processing, offering higher efficiency than traditional rotary pick-and-place technologies. This level of throughput makes the system highly competitive for Tier-1 OSAT (Outsourced Semiconductor Assembly and Test) providers and IDMs (Integrated Device Manufacturers); it is estimated that its average selling price (ASP) is approximately double that of the legacy Mi20 model.

Intelligence and Inspection

The Mi Quantum is equipped with the "MiND.X" vision platform, which utilizes AI-assisted decision-making to reduce both false positives and false negatives, thereby enhancing the accuracy of sorting decisions. It should be noted that the more advanced "9S" AOI (Automated Optical Inspection) suite—which includes infrared inspection for sidewalls, the backside, and laser-grooved areas—is a feature of the Quantum Plus platform; the Mi Quantum itself focuses primarily on standard optical inspection combined with AI-based vision capabilities.

Automation and Positioning Summary

The system supports dual-track configurations and de-taping options, and can be equipped with automated magazine and reel-changing systems to meet the requirements of Industry 4.0 production lines. As a dedicated die sorter, the Mi Quantum does not perform electrical testing. Its market differentiation lies in its ultra-high throughput and AI-driven vision, positioning it specifically for high-volume WLCSP sorting applications.
