We are going to take a look inside an iPhone 5s using a high resolution x-ray inspection system - the TruView 200. This system packs an impressive 130kV microfocus source and a large 3"x4" x-ray sensor capable of delivering 1um resolution.

We know voids in ball grid arrays (BGA) can be problematic to the reliability of any electronic product. In our x-ray inspection of the iPhone 5S, we noticed that the Apple 338S120L chipset had a large number of voids. So the natural next step was to use the BGA inspector included in the TruView 200 to measure the voids.

A quick analysis of the BGA voiding in the Apple 338S120L shows voids as large as 35%. That does not mean this is a problem, but certainly something a quality manager would need to check and validate. Besides, none of the other surface mount components in the iPhone 5S have this level of voiding.
-
The BGA inspector allows us to visualize the void in a 3D representation of x-y and density as the height of the volume.
