Quality Assurance
Image Inspection
-
We optimize the image inspection process depending on the coil shape.
Inspections are conducted from various angles by changing the position of cameras and coils.
Air cleanliness
-
The environment of the plant has been enhanced through the introduction of a clean unit, etc.
(Cleanliness of Class 100,000 [0.5 µm] is maintained and controlled.)
Analysis
Case 1 (High-speed camera)
- A high-speed camera is used to check the operation in slow motion. This helps analyze phenomena that cannot be detected otherwise and improve quality.
- The images above were used to analyze an upward flow of solder in the coil soldering process.
Case 2 (Microscope [ filter paper test ])
- Foreign matter that adheres to coils is automatically counted to improve the analysis efficiency.
Electrical properties inspection
- Resistance, withstand voltage, layer short circuit, impedance, and inductance can be measured depending on the coil specifications.
Image dimension measuring device
- This equipment is installed on each floor to eliminate dispersion in manual measurement and improve the work efficiency.
