X-ray multifunctional quality detector is an important non-destructive testing equipment

X-ray multifunctional quality detector is an important non-destructive testing equipment, widely used in electronics, semiconductor and other industries. X-rays are electromagnetic waves and photons with a very short wavelength and have strong penetrating ability. The penetration effect is affected by the wavelength, density and thickness of the material being penetrated. Generally speaking, the shorter the wavelength, the greater the penetrating power; the lower the material density and the thinner the thickness, the easier it is to be penetrated. When X-rays are irradiated on the object to be detected, due to differences in the degree of absorption of X-rays in different parts of the object, the intensity of the rays transmitted through the object is divided into
