... thermal probes which provide better than 100 nm resolution for both the topography and thermal images. Shown to the right are SEM images of one of these probes. The cantilever is made of SiN with a thin metal wire deposited so that the highest resistance portion of the wire is near the apex of the t ...

... ΨJT – junction to top thermal characterization ΨJB – junction to board thermal characterization The equations are the same as those for thermal resistance q except that the power P is now the total power, not just the power in that direction. For example, if only 5% of your total heat loss is down t ...

Lumped element model
The lumped element model (also called lumped parameter model, or lumped component model) simplifies the description of the behaviour of spatially distributed physical systems into a topology consisting of discrete entities that approximate the behaviour of the distributed system under certain assumptions. It is useful in electrical systems (including electronics), mechanical multibody systems, heat transfer, acoustics, etc.Mathematically speaking, the simplification reduces the state space of the system to a finite dimension, and the partial differential equations (PDEs) of the continuous (infinite-dimensional) time and space model of the physical system into ordinary differential equations (ODEs) with a finite number of parameters.
