Surface-mount soldering is a process where components are soldered onto the surface of the circuit board. Most electronics manufacturers use surface-mount technology (SMT) because it can be automated and is more cost-effective.

In industrial manufacturing, a machine uses a stencil to lay down solder paste onto the circuit board. Robotic arms precisely pick and place each component onto the board. The board passes through an oven, where the solder paste melts and solders the components to the board.

Surface mount components are significantly smaller than through-hole components, making them difficult to solder by hand. But with a bit of patience, practice, and a good magnifying glass, you can become proficient in surface-mount soldering!
