What is SMT Assembly?
SMT (Surface Mount Technology) assembly is a method for producing electronic circuits in which the components are mounted directly onto the surface of printed circuit boards (PCBs). This technology has largely replaced the through-hole technology construction method of fitting components with wire leads into holes in the circuit board. SMT allows for the production of smaller, faster, and cheaper electronic devices.
The SMT assembly process involves several steps:
- Solder Paste Printing: Solder paste, a mixture of tiny solder particles and flux, is applied to the PCB using a stencil printer.
- Component Placement: The components are placed onto the solder paste deposits on the PCB using high-speed, automated pick-and-place machines.
- Reflow Soldering: The PCB with components is passed through a reflow oven, which melts the solder particles in the solder paste, creating permanent electrical connections.
- Inspection and Testing: The assembled PCBs are inspected and tested to ensure quality and functionality.
