Using Filter in PCB Inspection
Original Image: A high-resolution image of the PCB is captured.
Image Processing: The image undergoes initial processing, such as noise reduction and enhancement.
Green Filter Application: A green filter is applied to the processed image. This filter selectively transmits green light, while blocking other colors.
Filtered Image: The resulting image highlights components or features that appear green or have a strong green
component. Defects or anomalies that stand out against the green background become more visible. -
Key benefits of using a green filter in PCB inspection
Defect Detection: Green filters can help to identify defects such as solder voids, misaligned components, or missing parts that may be difficult to detect in the original image.
Component Inspection: Certain components, such as resistors or capacitors, may have a distinct green hue. A green filter can enhance the visibility of these components and facilitate their inspection.
Background Reduction: By filtering out unwanted colors, the green filter can reduce the background noise and improve the contrast of the desired features.
Customization: The choice of filter color can be customized based on the specific requirements of the inspection task. For example, if the PCB contains components with a specific color, a filter matching that color can be used to enhance their visibility.
