interface resistance

interface resistance

[′in·tər‚fās ri′zis·təns]
(thermodynamics)
Impairment of heat flow caused by the imperfect contact between two materials at an interface.
Quantitatively, the temperature difference across the interface divided by the heat flux through it.

In the gas tightness test, the electrical interface resistance between the compliant pins and their hole walls was measured for selected pin connections before and after storage in an environment saturated with aggressive gases.
The interface resistance between pin and hole wall is normally measured by creating an electrical bias between the tip of the pin that protrudes on the secondary side of the board and the top side of the hole plating, and then measuring the current in a circuit between the top side of the pin and the bottom side of the plated holes (FIGURE 46, online).
In addition, they have very low interface resistance with metals: 10,000 times below that of the best organic polymers.
They do exhibit greater interface resistance between mated contacts .
Such a combination also minimizes contact interface resistance and material transfer.
With this high conductivity, these metal TIMs offer the lowest thermal interface resistance, enabling design of higher power and smaller electronic devices.
The interface resistance will increase as the connectors are mated and de-mated, as well as increase as the lead material oxidizes.
These products offer similar advantages by having the cooling tube system directly fabricated and integrated within the composite for reduced thermal interface resistance.
The interface resistance between the DUT and the heat sink applied to the face of the device.
and the source-gate and drain-gate interface resistances are given by
