(lower radiated emissions) due to the smaller radiation loop area (because of the smaller package) and the smaller lead inductance。 Disadvantages Manual prototype assembly or component-level repair is more difficult and requires skilled operators and more expensive tools, due to the small sizes and lead spacings of many SMDs
