X-Ray Inspection

1 Test Purpose

    X-ray inspection is a method of detecting the internal defects of a sample by X-rays using the ray intensity after attenuation of each part of the sample, depending on the difference in X-ray absorption rate and transmittance between different parts of the sample. 

    X-ray is key using as following:          

    - Inner line open or short

    - Adhesive issue

    - Package crack and void

     -Soldering issue

     …

     X-RayCategory: 2D X-ray and 3D X-ray (CT)
