I. How to use SMT reflow oven machine correctly?
1. Choose the right material and the right way to SMT reflow oven machine.
Selection of materials is very critical, must be selected by the authority recommended, or previously used to confirm that it is safe. There are many factors to consider when choosing the material, such as the type of soldering device, the type of circuit board, and the condition of its surface coating. As for the correct method, it is necessary to carry out according to their own actual situation, remember not to completely imitate others, because of the different types of components and the distribution of different components on the board and the number of these need to be carefully studied.
2. Determine the process route and process conditions, which is to develop a sample of lead-free soldering. After selecting the material and determining the method, the test of the soldering process can be started, so it cannot be neglected.
II. When selecting the reflow soldering should choose the correct method to reflow soldering.
1. Check the reflow soldering inside the debris, do a good job cleaning, to ensure safety, boot, select the production program to open the temperature settings.
2. Reflow soldering machine rail width should be adjusted according to the width of the PCB, open the air transport, mesh belt transportation, cooling fan.
3. According to the welding production process given parameters strict, strict control reflow soldering machine computer parameter settings, every day on time to record the reflow soldering machine parameters.
4. in order to open the temperature zone switch, to be set when the temperature rises to the temperature can start over the PCB board, over the board to pay attention to the direction.
5. The reflow conveyor belt width adjusted to the appropriate position, the width and flatness of the conveyor belt and circuit boards in line with the inspection of the material to be processed batch number and related technical requirements.
6. Small reflow soldering oven shall not be too long, high temperature caused by copper-platinum blistering phenomenon. Solder joints must be smooth and bright, the circuit board must be all the pads on the tin. Welded line must be re-passed, the second re-passed shall be carried out after cooling.
7. To wear gloves to pick up the welding PCB, can only touch the edge of the PCB, 10 samples per hour sampling, check the bad condition, and record data. Production process, if you find that the parameters can not meet the requirements of production, can not adjust their own parameters, you must immediately notify the technician to deal with.
8. Measuring temperature: the sensor will be inserted into the receiver socket of the tester in turn, open the tester power switch, the tester is placed in the reflow soldering with the old PCB board up over the reflow soldering, take out the computer to read the tester in the process of over the reflow soldering temperature data recorded, that is, the reflow soldering machine for the temperature curve of the original data.
9. The board has been welded according to the single number, name and other categories. In order to prevent the mixing of materials to produce bad.
III. Small reflow soldering machine operation emergency treatment
Emergencies occur when pressing the small reflow soldering machine on the other red emergency stop switch, which will make the main circuit stop and cut off the power supply, and then turn off the main power supply.
Do not use the emergency stop switch under normal circumstances, often use the emergency switch, so that the main circuit breaker contacts often jump, will cause it to prematurely damaged after the emergency stop, close the power switch, open the emergency stop switch, the system will return to the original operating state.
Features of NeoDen IN6 reflow oven
1. Heat insulation protection design, the casing temperature can be controlled within 40℃.
2. Household power supply, convenient and practical.
3. ESD tray, easy to collect PCB after reflowing, convenient for R&D and prototype.
4. NeoDen IN6 provides effective reflow soldering for PCB manufacturers.
5. The table-top design of the product makes it a perfect solution for production lines with versatile requirements. It is designed with internal automation that helps operators provide streamlined soldering.
6. The new model has bypassed the need for a tubular heater, which provides even temperature distribution throughout the reflow oven. By soldering PCBs in even convection, all components are heated at the same rate.
