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 postitions cooperate to form a complete SMT line.
Compared with traditional technology, Surface mount techology has the characteristics of high density, high reliability, low cost, and smaller size, which reuires a more efficient processing SMT line.
According to the degree of automation, SMT production lines can be divided into automatic SMT lines and semi-automatic SMT lines. The main difference is whether the pick-n-place machine is fully automatic or semi-automatic, in which, semi-automatic requires manual printing or manual loading and unloading of PCB boards.
Line efficiency is essential for every manufacturer and assembler. This goes especially for printed circuit board production. Line efficiency is the ratio of the number of hours a pick-and-place machine positions parts on the PCB divided by the quantity of hours the SMT assembly lines are staffed. The overall aim is to manufacture as many PCBs without quality loss of the product in the shortest period of time.
