What is SMT?
The vast majority of commercial electronics are all about complex circuitry fitting in small spaces. To do this, components need to be directly mounted onto the circuit board rather than wired. This is essentially what surface mount technology is.
Is Surface Mount Technology important?
A huge majority of today’s electronics are manufactured with SMT, or surface mount technology. Devices and products that use SMT have a large number of advantages over traditionally routed circuits; these devices are known as SMDs, or surface mount devices. These advantages have ensured that SMT has dominated the PCB world since its conception.
