In another life we needed a zero dimension way of measuring temp in a
laminar construction and our R&D people found a supplier of thin film
thermocouples. These would seem to fit your bill.

As is the way of things these days the lab and people are long gone so can't
ask them supplier details for you, but maybe an Internet search or just
mentioning them here will turn something up.

Kind Regards

Hi Mark,
Your concern about too large thermocouples is appropriate--they definietely
impact the results. I did some work like this many years ago [Ref:
Engelmaier, W., "Thermal Characterization of Multilayer Printed Wiring
Boards
During Lamination," Proc. 11th IEEE Electrical/Electronics Insulation Conf.,
Chicago, IL, October 1973, p. 208] and used 1-mil-diameter
thermocouples--you
need to treat them gingerly however.
