How Edge AI is Revolutionizing the Quality and Efficiency of IC Packaging and Testing

(A) Die Sorting: A Solution for Reducing the Die Sorting Cycle

Die probing and sorting are critical steps in ensuring product quality and manufacturing efficiency. By identifying defective chips, performing quality grading, and enabling defect repair, manufacturers can lower production costs, improve yield rates, and address diverse market demands—ultimately enhancing overall business outcomes and competitiveness.

By integrating cutting-edge technologies such as machine vision, artificial intelligence (AI), and edge computing, along with multi-axis synchronized control and high-performance hardware, the sorting process can efficiently distinguish between good and defective dies. Manufacturers are continuously optimizing their sorting workflows by adopting real-time data analytics, modular design, and automation to accelerate inspection speed and enhance accuracy. Dies are classified by specification, with out-of-spec units filtered out in early stages, while subsequent sorting steps focus on precise quality categorization—significantly improving yield and production effectiveness.

The reason die sorters need to integrate machine vision and motion control systems is that such combination enables accurate alignment and fast feedback, essential for high-speed and high-precision sorting. The vision system detects die surface quality, position, and dimensions in real time, feeding data to the motion system, which executes accurate multi-axis actions such as pickup, rotation, sorting, and placement. The motion system ensures die stability during high-speed operation, minimizing errors from vibration or misalignment. This reduces the sorting cycle, limits manual intervention, and increases both productivity and reliability—ultimately meeting evolving market needs.

(B) Wafer Saw: High-Precision Visual Positioning Solution for Wafer Dicing

Edge AI systems offer intelligent inspection solutions for wafer dicing by addressing the limitations of manual alignment and improving positional accuracy through AI-based automation. This technology strikes a balance between operational efficiency and reduced labor dependency. In a typical use case, an industrial camera captures images of the dicing position under controlled lighting. These images are transmitted from the wafer saw machine to the edge AI system via a network switch. The AI system analyzes and compares the image data to verify whether the cutting position is aligned. If misalignment is detected, the AI system automatically initiates a calibration procedure, instructing the dicing machine to perform precise corrections.

(C) Die Bonding: High-Precision Die Attach through Vision and Motion System Integration

As semiconductor processes continue to advance, IC die bonding has become an increasingly critical stage in the back-end packaging process. This step requires extremely high precision to attach the die onto the package substrate, directly influencing the performance and reliability of semiconductor devices. As such, the die bonder is considered one of the most vital pieces of equipment in the packaging and testing segment.

The die bonder picks up individual chips from diced wafers and accurately places them onto substrates. The bonding is typically performed using silver epoxy, ensuring firm adhesion between the chip and the substrate. To meet the demands of modern semiconductor packaging, die bonders must support high-speed, high-precision operations, including alignment, flipping, and continuous placement. As bonding accuracy standards become increasingly stringent, traditional optical inspection methods can no longer meet micron-level precision and stability requirements. Therefore, the adoption of automated precision die bonders has become essential—not only improving yield and efficiency, but also minimizing human error and enhancing process stability.

During the IC die bonding process, the motion system and vision inspection system inside the bonder work in tandem to perform ultra-fast and highly accurate die alignment. The vision system is responsible for real-time detection of the die’s position and angle. It uses image processing algorithms to calculate the relative position between the die and the substrate and provides compensation data. The motion system then dynamically adjusts its actions based on this data to ensure precise pickup and placement. This synchronization avoids cumulative errors and keeps bonding deviation within the micron (μm) range.

Insufficient bonding precision can result in electrical misalignment or degraded thermal conductivity, directly affecting product performance and even the success of the packaging production line. Thus, the coordinated operation between the vision system (providing real-time calibration data) and the motion system (executing high-speed, accurate adjustments) is essential to building high-precision die bonding equipment.
