What is smd?

SMD stands for Surface Mounted Device. It refers to electronic components that are mounted directly onto the surface of a printed circuit board (PCB). SMD components are smaller and more compact than traditional through-hole components, allowing for higher component density on the PCB.

SMD components are typically soldered onto the surface of the PCB using techniques such as reflow soldering or hand soldering with a soldering iron. They come in a variety of package styles, including resistors, capacitors, diodes, transistors, and integrated circuits.

Advantages of SMD components include their small size, lightweight, and high-performance capabilities. They also offer improved electrical performance due to shorter signal paths and reduced parasitic capacitance and inductance.

SMD components are widely used in a range of electronic devices and applications, including smartphones, computers, televisions, and automotive electronics. They have largely replaced through-hole components in modern electronics manufacturing due to their compact size and reliability.
