One great advantage of such a system is the ability to use it as a combination tool, or two stand-alone tools that can be used for various other types of inspections when needed. For instance, a 2D inspection tool was also used to inspect solder joints on standard SMT connectors, pin-thru-hole connections etc, and for analyzing internal component defects. The CT scan could be used for understanding other types of defects, such as, shorts internal to the components, internal structures of circuit boards etc.
Key Words: High density connectors, 2D X-ray inspection, CT scan, solder joint, IPC requirements for solder joints, automation.
