Key Considerations When Purchasing Reflow Soldering Equipment

When purchasing reflow soldering equipment, the following points should be considered: Verify the control method of the equipment: Reflow soldering systems controlled by a computer + PLC offer high temperature control accuracy, user-friendly operation, and memory functionality, making them suitable for products with diverse varieties and stringent soldering process requirements. However, the cost will be relatively higher. Button-operated + PLC-controlled reflow soldering equipment is more cost-effective compared to computer-controlled systems, making it suitable for products with a limited variety and less stringent process requirements. Confirm the product dimensions and production volume: For products with a width of less than 350mm, small-scale reflow soldering equipment (with six or fewer temperature zones) is generally recommended. For higher requirements, large-scale reflow soldering equipment is advised. For products with a width exceeding 350mm, large-scale reflow soldering equipment with six or more temperature zones should be selected. Of course, larger systems have their advantages, and smaller systems have theirs; choose based on your specific needs. Confirm the cooling method of the equipment: The main cooling methods for reflow soldering equipment include natural air cooling, electric fan cooling, plasma air cooling, water cooling, and ammonia N2 cooling. The most common cooling method for reflow soldering is air cooling. Compared to this, water cooling and ammonia cooling are superior options, but these are relatively more expensive.

Professional testing and evaluation: In addition to the above straightforward selection methods, there are also more specialised testing and evaluation processes to determine whether the reflow soldering equipment should be included in the procurement plan, as well as operational parameters to consider.

In summary, when purchasing reflow soldering equipment, factors such as control methods, cooling methods, product dimensions and production capacity, as well as professional testing and evaluation, should be taken into account.
