SMT lines or SMT production lines refer to the manufacturing facilities for PCB assembly and testing. Each process in SMT production has different flows and requirements, for which different processing machines and positions cooperate to form a complete SMT line.

Compared with traditional technology, Surface mount technology has the characteristics of high density, high reliability, low cost, and smaller size, which requires a more efficient processing SMT line.

SMT production line is also called surface assembly technology, and can be divided into automatic SMT lines and semi-automatic SMT lines.
