Hi People,

Does anyone have precise methods of isolating locations of shorts and opens
inside a finished PWB. Electrical Test, Probots and Micro-Ohmmeters hint at the
areas of the defects, but dont reveal the actual location. I am wondering if
anyone has tried Infared Thermal Imaging, High Resolution x-ray or Tracing high
frequency signals through a board. New project and little frustrated, Thanks
for any help.
