surface-mount technology

Abbreviated as SMT, surface-mount technology is a design standard for constructing electronic circuits where the components are mounted directly onto the the surface of the printed circuit board (PCB). The components have small metal tabs (or caps) that are soldered directly to the surface of the printed circuit board on tin-lead, silver, or gold plated copper pads, called solder pads.

Contrast with through-hole technology.
