DLF 1200 solid-material thermal diffusivity
TA Instruments · Engineering measurement and characterization
- Purpose
- Separate TIM material transport from assembled contact resistance.
- Technical approach
- DLF 1200 derives diffusivity from laser-pulse excitation and rear-face temperature response; conductivity also involves heat capacity and density.
- Scope of use
- Consider representative specimens, confirming dimensions, surface, direction and fixture/model.
- Limitations and open questions
These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitationsFilms, pastes and anisotropic materials need appropriate methods. Material conductivity does not establish assembled contact resistance or failure cause.
What to prepareBLNKK suggests geometry, density/heat-capacity basis, surface preparation, direction and temperature alongside interface-resistance comparisons.
Confirm with the supplierConfirm holders, references, pulse/heat-loss corrections and models; validate current configuration with representative samples.
- Public evidence
- The named brochure documents DLF1200; TPP029 demonstrates in-plane graphite measurements, not arbitrary TIM qualification.
