Design With Measured Data, Not Datasheet Assumptions.

Optical product engineers need Rth vs. BLT behavior at the thicknesses their packages actually use. Dynamic TIMs Testing separates contact resistance from bulk conductivity and returns Flotherm / FLOEFD-ready inputs.

SIM-TO-TEST MISMATCH

Your Model Is Only As Good As Its Material Inputs.

Thin bond lines behave non-linearly. When the model uses a datasheet conductivity, the correlation error shows up late — in build, not in simulation.

BLT SENSITIVITY
Non-linear thin-BLT zone
Rth may not scale linearly with thickness at thin bond lines, where interface resistance can become significant.
MODEL ERROR
Bad inputs, bad correlation
Bulk conductivity inputs can under-represent interface resistance in Flotherm and FLOEFD models.
REWORK
Late design changes
Thermal changes after mechanical design lock are typically costly and disruptive.
Get measured Rth vs. BLT curves at your actual stack conditions and drop validated properties straight into your thermal model.
