As one of the key processes in SMT assembly production line, the cleanliness of SMT reflow oven has a direct impact on the quality of the product. The accumulation of dust and residue in the furnace chamber may lead to problems such as bad soldering or short circuits. Therefore, regular cleaning of the reflow oven chamber is a necessary step to ensure production quality and efficiency. The following are some effective cleaning steps.
1. Safety check
Before cleaning, be sure to turn off and disconnect the power supply to the reflow oven to prevent accidental electric shock. Also, make sure the temperature in the furnace chamber is reduced to a safe range to prevent burns.
2. Disassemble the furnace chamber components
According to the design of the equipment, disassemble some removable parts in the furnace chamber, such as protective cover, filter, etc.. These parts usually need to be cleaned separately.
3. Rough cleaning
Use a scraper or metal brush to remove large particles of dust and residue from the furnace chamber. Be careful not to use too much force so as not to scratch the inner wall of the furnace chamber.
4. Meticulous cleaning
You can use professional hearth cleaner or anhydrous alcohol for cleaning. Use a soft cloth or sponge to wipe the inner wall of the furnace chamber, the residual dust and welding oil thoroughly cleaned. Special attention should be paid to avoid the cleaning solution getting into the electrical parts, or it may trigger a short circuit or malfunction.
During the cleaning process, pay special attention to the cleaning of the top and bottom of the furnace chamber, which are often the places with the most dust and residues. During the cleaning process, care should be taken that the cleaning agent inside the furnace chamber should be evenly applied and thoroughly wiped dry after cleaning to prevent residue of the cleaning agent.
After completing the above steps, the hot air vents and conveyor belts inside the furnace chamber need to be inspected and cleaned. The cleanliness of the hot air vents directly affects the quality of the weld and can be cleaned with special tools. Conveyor belt cleaning is also very important, you can use a clean cloth to wipe, for stubborn stains, you can use cleaners to deal with.
5. Reassemble the reflow oven
Make sure all parts are in place and working properly. After cleaning, the furnace chamber should be opened for empty heat treatment to remove residual cleaning agents and moisture.
In conclusion, the cleaning of the reflow furnace chamber is an important maintenance task that relates to the quality and efficiency of the production process. Cleaning must be thorough, including from rough cleaning to meticulous cleaning, to the treatment of special parts and the final empty heat treatment. Comprehensive cleaning not only improves productivity and reduces the occurrence of defective products, but also extends the service life of the furnace.
Reflow oven cleaning work needs to be carried out on a regular basis. According to the actual situation of production work, set a reasonable cleaning cycle to ensure that the equipment is always in good working condition.
Equipment users need regular training to understand and master the correct method of equipment cleaning and maintenance. Correct use and maintenance of equipment can not only improve productivity, but also to ensure the long-term stable operation of the equipment.
Finally, it should be noted that each reflow oven may have its own specific cleaning requirements and steps. Therefore, during the cleaning process, you need to refer to the equipment manual or contact your equipment supplier to ensure safe and effective cleaning.
Features of NeoDen IN8C reflow oven
1. Built-in welding fume filtration system, effective filtration of harmful gases, beautiful appearance and environmental protection, more in line with the use of high-end environment.
2. The control system has the characteristics of high integration, timely response, low failure rate, easy maintenance, etc.
3. Hot air convection, excellent welding performance.
4. The use of high-performance aluminum alloy heating plate instead of heating tube, both energy-saving and efficient, compared with similar reflow ovens on the market, the lateral temperature deviation is significantly reduced.
5. Independent circulating air design of the cooling area, completely isolated from the external environment on the internal temperature cavity.
