I usually use my fingers for that sort of test. :)
Warning. Don't try it on really hot chips! I have a small lump on my thumb
leftover from touching a chip that was trying to self-destruct. (bus clash)
Does anybody know of a low cost camera that works in IR? I expect somebody
probably makes a slightly modified version of one of the USB cameras for just
this sort of work.

Basically, take it apart, remove IR filter, add visible filter (old slide
film), put it back together.
