Reflow oven operation steps
1. Check that there is debris inside the equipment, do a good job of cleaning, to ensure safety, turn on the machine, select the production program to open the temperature settings.
2. Reflow oven guide width to be adjusted according to the width of the PCB, open the transport wind, mesh belt transport, cooling fan.
3. Reflow soldering machine temperature control has lead high (245 ± 5) ℃, lead products tin furnace temperature control at (255 ± 5) ℃, preheating temperature: 80 ℃ ~ 110 ℃. According to the parameters given by the welding production process strictly and rigorously control the reflow machine computer parameters setting, record the reflow machine parameters on time every day.
4. in order to successively turn on the temperature switch, to be temperature to the set temperature when you can start over, PCB, board, over the board pay attention to the direction. Ensure that the distance between 2 consecutive boards of the conveyor belt is not less than 10mm.
5. The reflow soldering conveyor belt width adjustment to the appropriate position, the width of the conveyor belt and flatness and line board, check the material to be processed batch number and related technical requirements.
6. Small reflow soldering machine shall not be too long, the temperature is too high caused by the phenomenon of copper platinum blistering; solder joints must be smooth and bright, the circuit board must be all pads on the tin; poorly soldered lines must be re-over, the second re-over shall be carried out after cooling
7. to wear gloves to pick up the solder PCB, only touch the edge of the PCB, sampling 10 samples per hour, check the bad condition, and record data. During the production process, if you find that the parameters cannot meet the requirements of production, you cannot adjust the parameters yourself, you must immediately notify the technician to deal with.
8. Measure the temperature: plug the sensor in turn into the tester’s receiving socket, turn on the tester power switch, place the tester inside the reflow solder with the old PCB board up over the reflow solder, remove the tester with a computer to read the temperature data recorded during the reflow soldering process, that is, the original data for the reflow soldering machine’s temperature curve.
9. Will have soldered the board according to the single number, name, etc. classified put. In order to prevent mixing materials to produce bad.
Reflow soldering oven operation precautions
1. Do not touch the mesh belt during operation and do not allow water or oil stains to fall into the furnace to prevent burns.
2. Welding operations should ensure ventilation, to prevent air pollution, operators should wear good work clothes, wear a good mask.
3. Often test the heating at the wire, to avoid aging leakage.
