Grahic Jump Location
The thin film is placed between the sensor and the blotter so that the saturation point can be determined
Grahic Jump Location
The TC Probe™ is calibrated with known reference standards to produce a linear calibration equation (r=0.996). The screen capture shows the coordinates of the triplicate tests conducted on each sample as well as the name of each material: laf, cal3 and hdpe, respectively, left to right.
Grahic Jump Location
A sketch of blotter overlay results illustrates the effect of metal and foam blotters on the slope of the traces
Grahic Jump Location
Thermal conductivity decreases with increasing planarity index
Grahic Jump Location
The separation of plots indicates the point where the heat wave has penetrated one layer of the PI-1 sample (0.3525 s1/2 )
Grahic Jump Location
No deviation occurs between these two averaged blotter plots for two layers of PI-1, indicating that the heat wave has not passed into the blotter material and that the results represent only the polyimide film
