Sample text

It is important to develop a good understanding of these nondimensional numbers. The set of interest to us is as discussed in subsequent sections. Nusselt Number Nusselt number shows the relationship between a fluid’s capacity to convect heat versus its capacity to conduct heat. Nu = hL K Grashof Number Grashof number provides a measure of buoyancy forces of a particular fluid. Gr = L3ρ2 gβ ∆T µ2 Prandtl Number Prandtl number shows the relationship between the capacity of a fluid to store heat versus its conductive capacity.

The second approach provided a very conservative solution, and the third approach provided a conservative and yet realistic solution. A Word on Edge Guides In a number of packaging designs, board edge guides can be used to conduct heat away from the PCB. To take advantage of this feature, the ground plane of the PCB must be placed as close to the surface as possible. Furthermore, the higher the contact pressure between the PCB and the guide, the lower the thermal resistance. Typical values of thermal resistance range from 20°F in/W for the U or G guides to 10°F in/W for the Z type guides to 4°F in/W to wedge clamps.

Convection takes place in liquids and gases. The molecules in fluids are not as tightly spaced as solids; thus, heat packets move around as the fluid moves. Therefore, heat transfer is much easier than conduction. 1. However, h is defined as the coefficient of heat transfer, and A is crosssectional area between the solid generating heat and the fluid carrying it away. 5 6 Practical Guide to the Packaging of Electronics Radiation takes place as direct heat transfer from one region to another. Similar to light, it does not require a medium to travel.
