An assembly densely populated with large components like Ball Grid Arrays (BGAs), Quad Flat Packages (QFPs), and heat sinks absorbs and distributes heat very differently than a board with a sparse layout of small, discrete components. Large components can act as heat sinks, drawing thermal energy away from the solder joints and creating \u201cthermal shadows\u201d that prevent smaller nearby components from reaching the required temperature.
