X-ray-Am I Looking in the Right Direction?

摘要

X-RAY INSPECTION, AT present, requires mainly human analysis to see the flaws. This will be true perhaps unless, or until, artificial intelligence (Al) algorithms provide some alternative solution. However, with so many variables in the x-ray images of assembled boards,- the shapes, sizes and density of bumps and joints, the differences in pad solder coverage, the presence of internal copper traces, the overlapping internal and bottom-side components and features, etc. - obtaining an initial training set of exemplars for a ubiquitous Al solution may be tricky.
