components attach to pads on a circuit board&#8217;s surface.

Surface-mount technology (SMT) often suits compact layouts and automated assembly; through-hole technology (THT) can be useful when a selected component or its mechanical load calls for it. Many boards use both. The right choice depends on the parts, the forces they encounter, the board layout and the production plan.
