Fixed Competitive Price Aoi Machine Vision - High Speed Full-Automatic PCB SMT Solder Paste Printer PCB SMT Stencil Printer – Xinling

Modern solder paste printing machine is generally composed of plate loading, adding solder paste, embossing, circuit board transmission and so on. Its working principle is: first fix the circuit board to be printed on the printing positioning table, and then the left and right scrapers of the printer leak the solder paste or red glue to the corresponding pad through the steel mesh. The PCB with uniform missing print is input to the mounter through the transmission table for automatic mounting.

Operation steps of SMT automatic printer:
1. Check and start the equipment before operation according to the operating procedures;
2. Place the PCB (the PCB deformation cannot meet the requirements of production, and a supporting plate shall be added) on the loading frame;
3. Place the screen on the printing press according to the direction pointed by the screen arrow;
4. Select the corresponding printing program according to the produced products, enter * * mode for screen calibration, and debug the printing state;
5. Printing adjustment: adjust the printing speed, pressure and angle to make the amount of solder paste printed on the PCB pad uniform;
6. The first article shall be confirmed by the technician and mass production shall be carried out after it is qualified;
7. Every 30 printed boards shall be inspected by the inspector and sent to the mounter after passing the inspection;
8. After the operation, remove the screen board and clean it, shut down it according to the operating procedures, and clean the worktable.

Requirements for SMT automatic printer:

1. Wear rubber gloves or disposable gloves when operating the solder paste. If the solder paste is accidentally adhered to the skin, immediately clean it with alcohol and hand sanitizer, and then clean it with a large amount of water;

2. The remaining solder paste, used screen wiping paper and disposable gloves after operation shall be treated in accordance with the relevant provisions of environmental regulations;

3. Clean the equipment, tooling and tools before use, especially pay special attention to the environmental protection status on site before processing lead-free products.
