Surface-mount technology (SMT), originally called planar mounting, [1] is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). [2] An electrical component mounted in this manner is referred to as a surface-mount device (SMD).

Nov 24, 2021 · This article gives an introduction to SMD, SMT, and PTH one by one, and it reveals the differences between SMT, SMD, and PTH components. We can conclude that SMT is the mainstream PCB assembly technology, and PTH is mainly used when there are plug needs.

SMT (Surface-Mount Technology) is a process for mounting electronic components onto PCBs, while SMD (Surface-Mount Devices) are the components themselves. Understanding both is key to optimizing PCB design and manufacturing efficiency.

Mar 22, 2025 · Surface mount devices (SMDs) are components used in the SMT (Surface Mount Technology) assembly process to adapt to PCBs that require small design and high density.

Surface mount devices or SMDs are the electronic components that are directly placed and soldered on the surface of the PCBs. The SMDs have smaller sizes than through-hole devices, whereas the through-hole devices take more space on the PCB, resulting in higher costs.

Oct 7, 2024 · SMT is a commonly used assembly method in modern electronics. The biggest advantage of this technology is that it allows for the rapid assembly of many electronic components onto a PCB (Printed Circuit Board).

Mar 20, 2025 · SMT-based SMD components enable high-density PCB assembly via automation, reducing parasitic effects and improving electrical performance. They replace through-hole leads, enabling miniaturization in consumer electronics, IoT, and aerospace. This innovation drives modern-day electronics miniaturization (like smd chips):

SMT (Surface-Mount Technology) is a method for placing components directly on PCBs, while SMD (Surface-Mount Device) refers to the components used in SMT. SMT allows for compact, efficient designs, while SMD components enhance production speed and product performance.
