SMT
n.n. Stands for Surface Mount Technology. A method of building electronic circuits where components are placed directly on the surface of a printed circuit board instead of being inserted into holes.
n. Abbreviation for Surface Mount Technology. A method of producing printed circuit boards (PCBs) by mounting electronic components directly onto the surface of the board, as opposed to through-hole technology.
The manufacturer switched to SMT to make the devices smaller.
Using SMT allows for much higher component density on a PCB compared to traditional through-hole assembly.
The transition from through-hole to SMT in the mid-1980s revolutionized the electronics industry by enabling the miniaturization of consumer electronics and the mass production of complex integrated circuits.
