2.Adjust the rail width. Duringadjusting, you can start with a faster speed; when the width of the rail is close to the width of the PCB, try to use a lower speed for precise adjustment.

3 .Adjustment of transportation speed. According to the time parameter of the solder paste and the furnace length adjustment speed, it is set to 80cm/min.

4.Set the temperature of each temperature zone as shown in the table.

5.During smt pcb assembly process, the temperature zone related parameter settings, generally the Ex-work settings, beginners do not change.

6.Fan frequency setting. The user can set the eye rate of each fan inverter. The option is 30-SoHz. The product PCR is thinner, lighter, less components, the frequency should be smaller, can be set to 30Hz; the components are larger, the cooling zone frequency can be set 40Hz

7. KIC temperature measurement.

8.If the parameters required for the smt pcb assembly are set properly, save the file here.

9.Select the workingmode of the operating mode, press the “START” button on the control panel or the “Start” button on the main interface, the machine starts heating.

10.Product production.

11.The production of the smt pcb assembly product is over.

12. Make sure there is no PCB in the furnace.

13.Shut down.
