Demonstration of PCB X-ray Application

1. Two Core Hardware Parts

• Panel Detector(0505A) : Rayence has built the world’s first full line-up of dental, medical, veterinary, and industrial X-ray detector products. Also, in Korea, Rayence is the only company that owns the techniques for designing CMOS wafer, developing flat panel detectors (TFT), and using the core technology of scintillator, which is used for radiation detection.

• Hamamatsu X-Ray Source(90KV) : The Hamamatsu microfocus X-ray sources have been evolved specifically for X-ray non-destructive inspection system. These X-ray sources equipped with an X-ray tube that has a small focal spot of several micro-meters to ten micro-meters, able to generating a clear X-ray picture even at a high magnification.
• The RS-232C interface is supplied as a widespread feature, permitting computerized operation with the aid of using outside control.
• The X-ray tube has an air-cooled and hermetically sealed structure, and is included with its excessive voltage electricity deliver for smooth handling. (High voltage cables are not required.)

2. Friendly Design of PCB Xray

• FPD instead of the table can tilt 60°, which won’t sacrifice magnification.
• The speed is adjustable, 5 axis coordination linkage system is adopted, which can maintain the image central while tilting.
• The speed is adjustable, 5 axis coordination linkage system is adopted, which can maintain the image central while tilting.
• The inspection procedures can be edited to achieve automatic inspection in large quantities.

3. Software Feature – Function Module

• Operation : Keyboard and mouse can finish all operations
• PCB X-ray Tube Control : Using mouse to click the X button can turn on or off the X-ray. The real-time tube voltage and current value will display beside, users can click up and down button, or drag the slider, or type to adjust.
• Image Effect Adjustment : The brightness, contrast and gain of the image can be adjusted freely to achieve a satisfactory result.
• Product List : Users can save the inspection parameters such as x-axis coordinates, contrast, brightness, and gain, and can directly call the parameters when inspecting the same product, to improve the inspection efficiency.
• Navigation Window : After the camera takes a photo of the table, click anywhere in the photo, the table will move to the place you click and display on the screen.

4. Software Feature – Void Rate Measurement

• Automatic Calculation : Click on two points to determine a rectangle. The software automatically finds and measures the edge of the solder ball in the rectangle, the pad and the internal voids, and can get the data of the voids rate, the area of the solder ball, the circumference, the biggest void’s rate, the length and the width, and indicates NG or OK by red and green
• Parameters Adjustment : Users can adjust the grayscale threshold, pixel, contrast, size filtering and other parameters to get accurate results of automatic calculation.
• Add Voids Manually : Users can draw a polygon or a free figure and calculate it as a void into the void rate.
