Why use X-rays to check electronic components

20/04/2021

X-ray, commonly known as x-ray, has the function of penetrating objects for perspective, so it is often used to detect internal defects of objects. The application range is wide, and the electronic semiconductor industry needs to use the performance of X-ray inspection equipment to inspect the product quality.
 
Electronic semiconductors often need to detect SMT, circuit board placement. The items that need to be tested include internal bubbles, internal slag, inclusions, cracks, missed welding, etc.
 
Why choose X-ray instead of other inspection equipment? For example, AOI still has electromagnetic vibration?
 
The functions of X-ray, AOI, and electromagnetic vibration are different: The basic principle of AOI is to check whether the components are mounted correctly, whether the position is good, whether there is any defective equipment such as missed and reversed through the reflection of light. But if the PCB board is placed in the wrong position or there is oil on the surface of the board, the test results will be greatly reduced
 
X-RAY is X-ray. The principle is to use the characteristic of X-ray to penetrate non-metallic substances to check whether the lower part of components such as BGA is well welded and whether there is a short circuit. The electromagnetic vibration test bench uses the principle of resonance and alkaline detection to detect defective products to a large extent. However, the operation of the test bench is complicated and the details are cumbersome. It is difficult for the experiment to play its role without calibration.
 
Recommended X-ray inspection equipment for electronic components: AX8200. This type of X-ray inspection machine is mainly used for electronic component inspection, with stable performance and excellent inspection results. It is suitable for BGA, CSP, flip chip inspection , semiconductor , large circuit boards. Packaging components, electronic connector module testing, printed circuit board solder joint testing, ceramic products, aviation components, solar panel battery industry and other special industry testing. For large circuit boards and large panels (same modules can be placed), CNC programming can be carried out and the automatic detection accuracy and repeat accuracy are high.
