Noncontact Measurement of Thermal Conductivity of Epoxy Bonds by Pulsed Photothermal Radiometry

摘要

Pulsed photothermal radiometry relies on the flash heating of a surface and the detection of the time-dependence of the surface cooling by infrared radiometry. This is useful as a non-destructive and non-contact technique to quantify the thermal conductivity of a subsurface epoxy bond underneath an opaque surface. The degree of curing of the epoxy can also be monitored.
