Open rotary screen printing machine is a device that prints solder paste or repair glue onto PCB pads through screen. It is mainly used in electronic processing industry, screen printing marks of printed circuit boards, signs of instrument shell panels, Solder paste printing during circuit board processing.

The following are some points introduced by the manufacturer of the automatic Open Type Rotary Screen Printer （https://www.hotairstenter.com/product/）. Pay attention to the precautions when turning on the open rotary screen printing machine: Points to note when opening the open rotary screen printing machine. Turn on the power of the screen printer and air compressor, and then open the start handle of the air compressor. When the handle is in the vertical direction, it is closed. When the handle is placed horizontally, it is open.

Turn on the power switch on the operation panel of the open rotary screen printing machine, and the touch screen will start to work. At the same time, put the screen printing template in the arm plate seat and fix it with a knob to facilitate subsequent adjustment of the screen printing template. About three minutes after starting the hand, the pressure of the street oil storage tank reaches 4, and the exhaust valve on the air compressor can be opened. The valve stem closes when it is perpendicular to the trachea, while it opens when it is parallel to the trachea. Driven by compressed air, the arm plate seat of the sieve plate holder will rise to the upper limit position to stop.

Select the jog function, select the placement position, and then the arm plate base is lowered to the top of the honeycomb fixing table of the printed circuit board. At this time, the fixed printed circuit board on the honeycomb fixing table is determined according to the position of the pad on the Hot Air Stenter （https://www.hotairstenter.com/product/hot-air-stenter.html） template. Approximate location. After determining the approximate fixed position of the printed circuit board, first rise in the middle to raise the arm steel plate seat to the upper limit position, and then use a thimble to place the printed circuit board on the honeycomb fixing table.
