A Multi-Technique Platform for Non-Invasive PCB Performance Evaluation
Agency / Branch:
DOD / USAF
A highly sensitive magnetic microscope with submicron resolution will be used to identify and assess difference between good, defective, and failing printed circuit boards (PCB)in order to develop a non-invasive technique for automatically detecting defects in PCBs. Three sensor types, SQUID, GMR, and MTJ will be tested to determine the best sensor or combination of sensors for this application. An optimized subtraction algorithm between images acquired on standard good and failing parts will be used to classify changes associated with common defects. The magnetic sensors used will have the ability to acquire 3-dimensional information on circuit damage with resolution better than 100 nanometers. In Phase II, magnetic data will be coupled with 3-D Xray technology to acquire a complete physical and electrical profile of defects in PCBs.
