T
raditionally, thermal analysis of
electronic components has been
rather unscientific. You would run a
device at full-tilt for a bit and poke it with your
finger; if it hurt, that component would probably
need a heatsink. Burnt fingers gave way to
temperature probes; temperature probes gave
way to non-contact thermometers; finally, non-
contact thermometers gave way to thermal
imaging equipment, capturing thermal data in
the same way a traditional camera captures light.
Over the past few years, the cost of
thermal imaging devices has been steadily
dropping (see Issue 146). It has now
reached the point where it’s possible to
buy smartphone add-ons for only a few
hundred pounds, or imaging modules that
allow the suitably clever to build their own
thermal cameras.
Regular readers will be aware of the
frequent use of thermal imaging analysis
in Hobby tech, using a relatively entry-level
FLIR C2 handheld camera. While functional,
the device is used outside its designed
environment here. The C2 is a semi-rugged
and compact camera aimed at people such
as site surveyors, typically targeting the
investigation of buildings and infrastructure
rather than compact electronic components.
The FLIR ETS320, by contrast, is designed
specifically for the analysis of electronic
