Applications
Five places where the thermal path decides what ships. The layer drops into each without a redesign. The evidence differs by segment, and we say so.
Sealed, fanless enclosures cannot take the heat their modules are rated for, so the silicon is derated and the performance that was paid for is not used.
On a production module, an industrial OEM measured the junction 11 °C cooler and junction-to-case thermal resistance 39% lower with a single Xtherma pad under the processor, with nothing else changed. Their engineers ran the test, on their instruments, and wrote the report.
Power stages, inductors and transformer cores concentrate heat in places a heat sink cannot reach, and every degree at the hotspot costs rating, efficiency or lifetime.
As a passive insert inside a power-magnetics assembly at an industrial power OEM, the layer produced the lowest hotspot of four materials tested on the same rig, below graphite and aluminium nitride. Single runs, so indicative; the geometry was the OEM's choice, not ours.
Accelerator packages now dissipate more heat per square millimetre than their lids and cold plates were designed for, and the hottest spots sit under a few square millimetres of die.
The lid-integrated and architected formats put the layer exactly there, between the hotspot and the cooling you already run. Evidence to date comes from embedded modules and power magnetics; accelerator-class packages are in design-in evaluation now.
Weight, vacuum and vibration rule out most of the cooling toolbox. What flies is passive, light and solid.
The layer has no fluids, pumps or moving parts and weighs under half of the copper it replaces. Qualification for these environments is agreed programme by programme, with your reliability team.
Laser diodes, RF power devices and photonic packages live or die on a few kelvin at the junction: wavelength, efficiency and lifetime all follow it.
The layer spreads heat at the source, where a degree is worth most, in pad and plate formats sized to the device.
