Ø  The Innovation and Future Development of Machine Vision

Machine vision technology has already been applied in the electronics and manufacturing industries. Previously, traditional inspection methods relied on human visual inspection. While the human eye can distinguish differences between objects without prior learning, issues such as visual fatigue and inconsistencies in defect detection standards among inspectors arise. Additionally, manual inspection requires significant human resources. As a result, many industries have transitioned to machine vision to replace manual inspection.

 

Ø  What is Machine Vision？

Industrial machines are equipped with sensing vision instruments and industrial cameras, with optical inspection instruments playing a significant role. These instruments are widely used to detect various product defects.

 

Ø  Advantages of Machine Vision

1.   High Precision

2.   Non-Contact Inspection

3.   Consistency

4.   Cost Efficiency

5.   Flexibility

Machines, unlike the human eye, do not require rest, reducing unnecessary labor costs. Additionally, by simply updating and adjusting the installed software, inspection technology can be improved without replacing the entire set of equipment, avoiding significant expenses.

 

Ø  Application of Machine Vision in the Semiconductor Industry: Intelligent Detection of Defects, Flaws, and Faulty Points

The semiconductor industry is a crucial sector for Taiwan's development. Today, wafer manufacturing technology is advancing towards larger wafer sizes and smaller components on the dies. Therefore, die defect detection and thin film inspection before die packaging are critical processes.

The applications of flat panel displays are also becoming increasingly diverse. In addition to being lightweight and thin, flexible and foldable panels have been developed. However, during production, these displays may encounter issues such as bright and dark spots, dead pixels, scratches, and damages. Similarly, in the manufacturing process of printed circuit boards (PCBs), defects such as short circuits, open circuits, protruding traces, mouse bites, pinholes, and variations in trace width may occur.

How can these issues be detected in time, and how can manufacturing processes be improved to resolve them? Intelligent inspection technology has become an indispensable tool in the manufacturing industry.

Ø  AI artificial intelligence hyperspectral image recognition system enhances machine vision—new technology for defect detection

In addition to using grayscale or standard color images for defect recognition, we have a more advanced option—hyperspectral image recognition. Hyperspectral cameras can capture color images and perform rapid detection, using the "area" as the unit of inspection. With the integration of AI artificial intelligence, the system learns to automatically identify and classify defects with high accuracy. It can highlight defects more effectively than typical optical inspection images, and the amount of data collected is much larger, allowing for the extraction of crucial information. In addition to detecting defects and bad spots, hyperspectral image recognition can also measure coating thickness, such as checking whether the number of graphene layers meets the standard. Graphene is one of the thinnest known materials with strong properties, and through hyperspectral recognition technology, layer information can be obtained by measuring the transmittance.
