Every industry has some effective aids, and in the electronics industry, nondestructive inspection equipment is one of them. Since BGA monolithic chips are not distributed around the chip according to the traditional design, but on the bottom of the monolithic chip, it is undoubtedly impossible to judge the quality of solder joints according to the traditional manual visual inspection, so they must be tested according to ICT or even function. Therefore, the application of non-destructive testing equipment in SMT post-reflow inspection is becoming more and more widespread. It can not only qualitatively analyze solder joints, but also find and correct faults in time.

The working principle of NDT equipment.
 
1. first, nondestructive devices mainly use the penetrating power of X-rays. x-rays have a short wavelength and high energy. When a substance irradiates an object, only a small portion of X-rays will be absorbed, while most of the energy of X-rays will pass through the interstices of atoms of the substance, showing a strong penetrating power.
 
2. Nondestructive devices can detect the relationship between x-ray penetration and the density of a substance, and can distinguish between substances of different densities by differential absorption. In this way, if the detected object has different thickness, shape change, different x-ray absorption and different images, it will produce different black and white images.

3. It can be used for IGBT semiconductor inspection, BGA chip inspection, LED light bar inspection, PCB bare board inspection, lithium battery inspection, and aluminum casting nondestructive testing.
 
4. Simply put, high quality fluorescence transmission images are output using interference-free microfocus nondestructive devices, which are then converted to signals received by flat panel detectors. All functions of the operating software are done with the mouse only, easy to use. Standard high-performance x-ray tubes can detect defects down to 5 microns, and some nondestructive equipment can detect defects down to 2.5 microns, and the system can be magnified up to 1000 times and the object can be tilted. Nondestructive equipment can be inspected manually or automatically, and inspection data can be generated automatically.
