What is Surface Mount Technology?

Surface Mount Technology (SMT) is a method used to mount electronic components onto the surface of a printed circuit board (PCB). This technology utilizes small and intricate parts that are directly placed on the PCB's surface. SMT provides high mechanical strength and is widely adopted for PCB assembly due to its efficiency and space-saving benefits. In SMT PCB assembly, both the leads and components are placed on the same side of the PCB, optimizing space utilization. This versatile technology is suitable for prototyping, mass production, and PCB repair, involving the use of solder paste for secure component attachment through soldering.
