How to use Full-auto SMT Stencil Printer correctly?

Full-auto SMT Stencil Printer is suitable for solder paste printing of surface mount components in SMT surface mount technology. Specifically, in the SMT electronic assembly process, the electronic fiber material is printed on the circuit board through the opening of the screen, and the purpose is to stick the chip electronic components. So, do you know how to use Full-auto SMT Stencil Printer? Next, let me introduce you.

What are the preparations for Full-auto SMT Stencil Printer?

① Clean the work surface of the Full-auto SMT Stencil Printer and the required tools, and place the items in the specified position;

② Choose Full-auto SMT Stencil Printer screen according to product model

③ Stir the naturally placed Desen solder paste with a solder paste mixing knife for 2-3 minutes or use a solder paste mixer to make the flux uniform;

④ The PCB received must be baked in an oven before use, and the temperature of the oven is adjusted to 100°C for 2-3 minutes.

What is the operation guide for Full-auto SMT Stencil Printer?

① According to the Full-auto SMT Stencil Printer operating procedures, carry out the equipment pre-operation inspection and start-up work;

② Place the PCB (the PCB deformation cannot satisfy the need to add a pallet during production) on the loading frame;

③ Place the screen on the printing machine in the direction pointed by the arrow on the screen;

④ Select the corresponding printing program according to the product produced, enter the tuning mode for screen calibration, and debug the printing status of the Full-auto SMT Stencil Printer;

⑤ Printing adjustment: adjust the printing speed, pressure and angle to make the amount of solder paste printed on the PCB pads uniform;

⑥ The first piece needs to be confirmed by the technician, and mass produced after being qualified;

⑦ Every 30 printed boards need to be inspected by an inspector, and then sent to the placement machine after being qualified;

⑧ After the operation of the Full-auto SMT Stencil Printer is completed, remove the screen and clean it, shut it down according to the operating instructions, and clean the work surface.

What are the specific requirements for using Full-auto SMT Stencil Printer?

① When handling the solder paste with Full-auto SMT Stencil Printer, you should wear rubber gloves or disposable gloves. If the solder paste is accidentally adhered to the skin, it should be cleaned with alcohol or hand sanitizer immediately, and then rinsed with plenty of water;

② After the operation, the remaining solder paste, the used Full-auto SMT Stencil Printer screen wipe paper and disposable gloves shall be treated uniformly in accordance with the relevant provisions of environmental laws and regulations;

③ Clean the equipment, tooling, and tools before use, especially the environmental protection status of the site before processing lead-free products.

④ During the operation of Full-auto SMT Stencil Printer, the body is strictly prohibited to reach into the machine;

⑤ The longest time from printing the solder paste on the substrate to entering the reflow soldering is no more than 4 hours;

⑥ Check the integrity of the squeegee before operating the Full-auto SMT Stencil Printer.
