6.1 Operation of the reflow soldering oven

①Shut down and cut off the power supply when repairing the machine to prevent electric shock or short circuit.

②The operator should carry out daily inspection of all parts for reflow welding, and pay special attention to the conveyor belt to prevent it from jamming or falling off.

③The temperature measuring equipment can not be in the high temperature state for a long time. After each temperature measurement, the temperature measuring equipment shall be quickly pulled out from the furnace cavity to avoid deformation.

In case of stopping heating in individual temperature areas, the corresponding safety pipe shall be checked first. During operation, attention shall be paid to avoid scalding at high temperature.

During the cooling mode, the operator should open the furnace to check whether there is any foreign matter in the furnace cavity, the close the furnace body at the end.

④Start reflow soldering and check whether the sound of hot air motor is abnormal.

Check whether the conveyor belt is normally squeezed and jammed during transportation. Ensure that the chain and each sprocket are well engaged and derailed.

Check the lubrication of each roller bearing. If any abnormality is found, press the emergency stop button immediately to prevent damage to the equipment.

⑤Operators shall regularly check and maintain reflow soldering equipment and make records.

⑥Check the power supply to check whether the equipment is well grounded, and check the reflow oven cavity to ensure that the internal foreign matters of the equipment.

⑦ Open the control software to set the temperature of reflow soldering. Generally, the furnace temperature reaches the set value in 20-30 minutes.

⑧The computer on the device is for the machine using. It is strictly prohibited to delete or change the data files, system files and batch processing files configured by the computer at will to avoid computer system confusion.

Notice: Do not use any mobile storage device to communicate with the computer without permission.

⑨Adjust the width of the guide rail slowly according to the size of the circuit board. The machine must be stable without tilting or instability. During operation, it is strictly prohibited to put other items into the furnace cavity except the circuit board and temperature measuring equipment.

⑩ Check that the four emergency switches at the end of the entrance and exit spring up and remove the four emergency switch protection rings.

⑪Check the power supply error of exhaust fan and then connect the power supply.

⑫Do not cut off the power supply before reflow soldering shutdown. The system will automatically enter the cooling operation mode. The hot air motor will continue to work for 10-15 minutes, and then the hot air motor will stop working. Then the heat source can be turned off.
