The small reflow soldering machine is suitable for small-scale SMT patch production and is relatively small in size. It is a welding technology that has developed with the emergence of miniaturized electronic products and is mainly used for the welding of various surface-mounted components. The small reflow soldering machine has the characteristics of high precision, multi-functionality, economic practicality, energy saving, stable performance, long service life, and visual operation. Small reflow soldering machines are generally instrument-controlled, and the operation is relatively simple. Now, Shandong Puhui Electric Technology will provide a detailed explanation of the operation steps of the small reflow soldering machine.
I. Startup Steps of Small Reflow Soldering Machine:
1 Turn on the power switch of the small reflow soldering machine.
2 Turn on the transportation switch of the small reflow soldering machine.
3 Adjust the transportation speed of the small reflow soldering to the appropriate speed for soldering.
4 Turn on the temperature zone temperature controller from OFF to ON. Press the SET button below the temperature control meter to make the data flash, select the change digit, the brightest digit or change the data (increase or decrease by 1 each time), and then press the SET button to save.
5 After normal startup for 20-30 minutes, observe the actual temperature on the temperature controller and the set temperature. After stabilization, if it is unstable, reset the temperature dual integral (hold down the SET button below the temperature control meter for about 10 seconds, when the data menu changes flashing, release your finger, then press it again to display the ATU menu, change 0000 to 0001, and then hold down the SET button until it stops flashing), observe the temperature controller again after 5-10 minutes, and proceed to the next step.
6 Test soldering with waste boards that are the same as the working PCB or similar, and adjust the temperature controller setting to within 5°C based on the results to meet the working requirements.
7 If the actual temperature of the temperature controller is unstable after just putting in the PCB board for about 5-10 minutes, reset the temperature controller parameters. (When the PCB board is first put in or the number of PCB boards put in is suddenly changed, there is a certain temperature difference between the actual temperature and the set temperature. After a period of uniform speed putting the PCB, this temperature difference will decrease to within the normal temperature difference range).

II. Shutdown Steps of Small Reflow Soldering Machine:
1 Check whether all the PCB boards inside the small reflow soldering furnace have been fully soldered.
2 Turn off the electronic speed control switch of the transportation belt from "RUN" to "STOP".
3 Let the small reflow soldering machine run empty for 10-15 minutes.
4 Turn off the electronic speed control switch of the transportation belt from "RUN" to "STOP"..
5 Turn off the air transport and cooling fan switch from "RUN" to "STOP".
6 Turn off the main power switch of the machine, press the red button.
7 Turn off the main power switch of the small reflow soldering machine.
8 Turn off the main power switch of the machine, press the red button.
III. Emergency Handling of Small Reflow Soldering Machine
1 If the small reflow soldering machine encounters an emergency, immediately press the other red emergency stop button on the machine, which will stop the main circuit and cut off the power, and then turn off the main power.
2 Under normal circumstances, do not use the emergency stop switch frequently. Frequent use of the emergency switch will cause the contacts of the main circuit breaker to jump prematurely.
3 After the emergency shutdown of the small reflow soldering machine, when the fault is resolved, close the power switch and open the emergency stop switch, and the system will return to its original working state.
4 The above is the detailed explanation of the operation of the small reflow soldering machine.
