This article explores the impact of visual inspection AI solutions in three different manufacturing plants: a semiconductor fab in Taiwan, an electronics contract manufacturer in Mexico, and an automotive assembly plant in the United States. We'll delve into their specific use cases, challenges faced, and the business impact of adopting visual inspection AI.

How AI is Used in Semiconductor Fabrication

Semiconductor fabs play a vital role in the electronics industry, producing silicon wafers and semiconductor chips. However, defects in the fabrication process can lead to a significant decrease in production yields and increased costs.

To address this challenge, semiconductor fabs are leveraging visual inspection AI solutions to detect defects at their source and reduce waste. In a semiconductor fab in Taiwan, a production yield engineer named Chen is taking the first steps to automate defect detection with a visual inspection AI solution.

Chen starts by collecting images of the wafers and imports them into a visual inspection AI dataset. He then creates labels for the Type of defects, such as scratches and discoloration. With the help of a simple user interface, Chen quickly annotates defect areas on the images.

One AdVantage of this visual inspection AI solution is that Chen only needs to annotate 10 images for each defect type, unlike other solutions that require a large dataset for training. After the training is completed, Chen reviews the model's performance against key metrics like precision and recall.

Once the inspection model is deployed, it can run autonomously either on-premises or in the cloud. This allows for scalability across multiple fabrication plants, ensuring consistent defect detection and reducing the total avoidable cost of production quality issues.

Improving Production Yields through Visual Inspection AI

Visual inspection AI can revolutionize the way PCB assembly lines identify and rectify defects. By automating the defect detection process and reducing rework and scrap, manufacturers can significantly improve production yields.

In an electronics contract manufacturing plant in Mexico, a manufacturing engineer named Maria is implementing a visual inspection solution across multiple PCB assembly lines. Maria starts by selecting one of the uploaded PCB images as a template image and defines inspection areas and individual components using bounding boxes.

The visual inspection AI solution then automatically localizes and crops component areas for all imported images. Maria can preview how the component detection and cropping will be applied and simply click "Apply to all" if it looks right. She then trains AI models for each of the components on the assembly board.

One unique feature of visual inspection AI is its active learning capability, which intelligently surfaces suspect images from Maria to label. By labeling a few normal and abnormal images, the assembly detection model retrains itself, further improving its accuracy over time.

Maria can review the model's performance for each component and assess metrics such as precision, recall, escape rate, and overkill rate. This allows her to continuously optimize the visual inspection process and improve the production yields of the PCB assembly lines.

The total avoidable cost from production quality issues in this electronics contract manufacturing plant can easily reach millions of dollars per year. With visual inspection AI, manufacturers have the potential to significantly reduce these costs and enhance overall operational efficiency.
