# Tips For Troubleshooting The Thermal Contact Resistance Error

Contents

If you’re getting a thermal contact resistance setting error, this guide should help.

Thermal contact resistance (TCR) is a phenomenon in which comfortable flow is prevented by the contact surface of two materials.

The term resistance to external influencesAction describes the contribution to the total resistance of the process, which can be attributed to all contact surfaces of power lines and, therefore, to connections in relation to the implied resistance. This effect is broadly described by the term electrical contact suppression (ECR) and arises from limited areas of true bonding at the interface and the appearance of resistive surface films, possibly oxide layers. ECR can vary with effort, mostly decreasing in a process known as brake creep. The concept of potential drop across the injection electrode was introduced by William Shockley[1] to explain the difference between the experimental results and the model channel approximation constant. In addition, the terms ECR, interface resistor, trimmer resistor, or simply correction are also presumably used. As a somewhat more general term, the term “parasitic resistance in life insurance” is used, which in fact usually means that contact resistance is the maincomponent.

## What does thermal contact resistance depend on?

Contact resistance is partly highly dependent on surface roughness, and holding two surfaces together definitely affects contact resistance. The resistance to thermal interaction decreases with a decrease in the roughness of the facade and an increase in interfacial pressure.

Here it is important to distinguish between the determination of the value of contact resistance in two-electrode systems (eg diodes) and three-electrode systems (eg transistors).

For two-device electrodes, the contact resistivity is undoubtedly determined experimentally as the slope of the I–V characteristic at V equal to 0:

$displaystyle r_c=leftfrac partial Vpartial Jright_V=0$

where J is the density, modern or current per unit area. Thus, contact resistance components are usually expressed in ohm-square meters and О© â‹… cm 2 displaystyle Omega cdot textcm^2

. With a linear function such as today’s voltage, the device tells you if you want ohmic contacts.

## What is meant by thermal contact?

Article from Wikipedia, the free encyclopedia. In thermal motion and thermodynamics, a thermodynamic system is said to be in thermal contact with another system when it can exchange energy very well through a process, most often involving heat.
