Printed circuit board production line and composition

- Jan 18, 2019-

Printed circuit board factories are made up of many production equipment, each of which works differently, but the ultimate goal of each equipment is to print circuit boards. PCB production equipment has the characteristics of automatic, high precision, high speed and high efficiency. So which production equipment is composed of PCB manufacturers?

 

The main production equipment of SMT production line includes solder paste printing machine, dispensing machine, SMT machine, reflow furnace and wave soldering machine. The auxiliary equipment includes inspection AOI equipment, X-RAY equipment, SPI equipment, rework equipment, cleaning equipment, drying equipment and Material storage equipment etc,.

 

SMT production lines can be divided into fully automatic production lines and semi-automatic production lines according to the degree of automation. The fully automatic production line means that the equipment of the entire production line is fully automatic, and all production equipment is connected into an automatic line through the automatic up board machine, buffer belt and automatic down board machine.

Semi-automatic production line means that the main production equipment is not connected or not fully connected. The printing machine is semi-automatic and requires manual printing or manual loading and unloading of printed circuit boards. According to the scale of the production line, the production line of printed circuit boards can be divided into large, medium and small production lines. The large production line has a large production capacity, and the SMT machine on a large single-sided production line consists of a general-purpose machine and multiple high-speed machines. Medium and small production lines are mainly suitable for research institutes and small and medium-sized enterprises, satisfying multiple varieties, small and medium batches or single varieties. Medium or small batch production tasks can use fully automated production lines or semi-automatic production lines. Depending on the different product being produced, the production line for printed circuit boards can be divided into single production lines and dual production lines. The single production line of printed circuit boards consists of automatic surface assembly equipment such as printing machine, SMT machines, reflow ovens, and test equipment. It is mainly used to assemble SMC/SMD products on only one side of the PCB.

 

The printed circuit board double production line consists of two printed circuit board single production lines which can exist independently or in series, and are mainly used for assembling SMC/SMD products on both sides of the PCB.
