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.

I found this while poking around.  How to modify your webcam:
Basically, take it apart, remove IR filter, add visible filter (old slide 
film), put it back together.

These are my opinions, not necessarily my employer's.  I hate spam.
