Visual Inspection <\/span><\/h1>\n

Using AI Technology<\/span><\/h1>\n

 <\/p>\n

1. Challenges in Conventional Inspection<\/strong><\/h2>\n

Power choke coils play a critical role in virtually all electronic devices\u2014
including smartphones, PCs, and automobiles\u2014by regulating current flow and protecting circuits<\/strong>.
The quality of this component directly affects the overall performance and reliability of the device.<\/p>\n

However, traditional visual inspection methods in manufacturing often face several challenges,
especially when detecting serious defects such as cracks or structural damage.<\/p>\n

I. Miniaturization of Defects<\/strong><\/h3>\n

As components become smaller, defects also become more microscopic,
making them extremely difficult to detect with the human eye.<\/p>\n

II. Variability in Human Judgment<\/strong><\/h3>\n

Inspector fatigue, differences in skill level, and subjective interpretation lead to
inconsistency in defect evaluation, making it difficult to maintain uniform product quality.<\/p>\n

III. Limitations in Inspection Speed<\/strong><\/h3>\n

High-precision inspection requires time.
As a result, manual inspection cannot keep pace with mass production speeds.<\/p>\n

To overcome these challenges, we implemented cutting-edge AI-based inspection technology<\/strong>,
significantly increasing the reliability and consistency of defect detection.<\/p>\n

2. AI-Driven \u201cAbsolute Quality Assurance\u201d<\/strong><\/h2>\n

By integrating AI technology, the inspection of choke coils evolves from
a process dependent on experience and intuition<\/strong> to one grounded in data, science, and automation<\/strong>.
This ensures a robust and highly reliable quality assurance system.<\/p>\n

How Our AI Inspection System Works<\/strong><\/h2>\n

1. High-Quality Training Data<\/strong><\/h3>\n

The AI model is trained using extensive datasets containing images of:<\/p>\n

(1)Normal, defect-free coils<\/p>\n

(2)A wide variety of defects, including cracks, fractures, and foreign-matter contamination<\/p>\n

This training allows the AI to acquire an accurate understanding of the
\u201cideal coil profile\u201d and subtle deviations from it.<\/p>\n

2. Rigorous Defect Detection<\/strong><\/h3>\n

When a choke coil passes beneath the inspection camera on the production line,
the AI captures the image instantaneously and analyzes key areas such as
the surface, edges, and junctions.<\/p>\n

The system applies strict and consistent criteria to detect serious defects\u2014
including cracks and structural damage\u2014that could compromise electronic device performance.<\/p>\n

3. Real-Time Sorting and Classification<\/strong><\/h3>\n

Once a defect is identified, the AI system immediately classifies the coil as non-conforming<\/strong>,
automatically removing it from the production line.
This prevents defective components from proceeding to subsequent manufacturing stages
and contributes to overall production efficiency.<\/p>\n
