E-cap and Tantalum cap, how difficult in ICT coverage?

If you are just wanting to test the values of the electrolytics or tantalums, it's not a problem with an ICT, as long as your system has an analog instrument to do it. If you are wanting to test the polarity of the cap, you will need a capacitive coupled sensor that mounts over the DUT to test the orientation. Now whether your system supports this option is another matter. Most should. What system do you have? Do you have an AOI that can test for orientation? If so, I wouldn't worry about incorporating this option on your ICT, unless you don't mind spending the money and have a thing for redundancy.
