1.1 Basic principle X-ray inspection equipment penetrates the sample to be inspected by x-rays, and then maps out an x-ray image on the image detector. The quality of this image formation is mainly determined by the resolution and contrast. The resolution of the imaging system depends on the x-rays.
X-ray inspection equipment is through the high-voltage accelerated electron impact metal plate released by the x-ray penetration of the sample, leaving an image, the technician through the brightness of the image to observe the relevant details of the sample. As shown in the picture above can detect PCB line breaks, IC defects, tin ball cracking and a series of abnormalities.
1.basic outline
x-ray inspection equipment through the x-ray penetration of the sample to be detected, and then in the image detector maps out an X-ray image, the image of the quality of the formation of the resolution and contrast is mainly determined by the x-ray detector, generally speaking, x-ray detector of the performance of the optical tube plays a very big role, the x-ray equipment of the Zhumao photoelectric are all used in the import of Japan. At present, all the x-ray equipments of JOMO adopt HAMAMATSU as the core parts imported from Japan.
2. x-ray tube
The x-ray tube mainly provides electrons from the hot cathode through the electric field to the anode to accelerate the role. When the electrons in tens of kilovolts of high voltage quickly speed up to a high-speed state, impact to the anode body when the kinetic energy into the release of X-rays. The size of the collision area is the size of the X-ray source, through the principle of small hole imaging, we can roughly know the size of the x-ray source and clarity inversely proportional to the size of the x-ray source, that is, the smaller the x-ray source, the clearer the imaging.
3. x-ray detector
The x-ray detector makes up for the lack of chemical film imaging in the past, through the detector can save costs while improving efficiency.
