Two Dimensional Area Thermal Profiling

      A thermal sensitive film was developed to permanently record
temperatures and thermal gradients present from contacting or
non-contacting heat source(s) at a particular surface or an interface
between two contacting surfaces.

      In the Figure the film 1 is shown at the interface between a
hot blade 2 and circuit card pads 3 on circuit board 4.  The film is
composed of thermal sensitive material 5 positioned between two inert
cover sheets 6.  The cover sheets 6 are designed to minimize lateral
heat transfer.  The heat sensitive layer 5 of the film is able to
change color or physical structure based on the maximum temperature
seen by the material at a given point.  Thus individual temperatures
are able to be determined and the nature of the thermal sensitive
material allows thermal gradients to be established.
