Estimating Temperature by Touch
I vaguely remember an engineer mentioning an old rule of thumb
for quickly estimating temperatures on circuit boards: you put
your finger on a component, and it went something like this:
Feels cool ... 25 to 35 deg C
Neutral ... 37
Warm ... 40 to ?
Very warm ... ?
Hot ... ?
Makes a blister... ?
Does anybody have the numbers that go in here?
