SMT, or surface mount technology, is an automated and versatile process used in electronics assembly. This process mounts electronic components onto a printed circuit board, providing manufacturers with a wide range of options for constructing circuit boards.
When compared to other techniques used in PCB manufacturing, surface mounting offers numerous benefits. Notably, it allows for significantly smaller products, with sizes up to one-third and weights up to one-tenth that of through-hole boards. This technology also enables manufacturers to place more complex circuits into smaller assemblies, making it a key element in the widespread use of small electronic devices in modern society.
