The advantages and functions of nitrogen in Lyra Reflow Oven

With the increase in assembly density and the emergence of fine-pitch assembly technology, nitrogen-filled reflow soldering processes and equipment have been produced, which have improved the quality and yield of Lyra Reflow Oven, which has become the development direction of Lyra Reflow Oven.

Nitrogen is of great significance in the use of Lyra Reflow Oven.

Soldering quality is particularly important in Lyra Reflow Oven. Solder paste with lower activity flux can be used, while at the same time it can improve the performance of solder joints and reduce the discoloration of the substrate. Now Lyra Reflow Oven manufacturers are working on the development of No-clean solder paste that can perform good soldering in an atmosphere with high oxygen content, so that nitrogen consumption can be reduced.

A cost-benefit analysis should be performed on Lyra Reflow Oven.

For the introduction of nitrogen into Lyra Reflow Oven, cost-benefit analysis must be carried out. Its benefits include product high-quality rate, quality improvement, reduction in rework or maintenance costs, etc. A complete and wrong analysis often reveals that the introduction of nitrogen does not increase the end result. Cost, on the contrary, we can benefit from it.

① Prevent and reduce oxidation during the work of Lyra Reflow Oven

② Improve welding wetting power and speed up the wetting speed of Lyra Reflow Oven

③ Reduce the production of solder balls, avoid bridging, and get good soldering quality

How to efficiently use the nitrogen in Lyra Reflow Oven?

Most Lyra Reflow Oven furnaces currently in use are of forced hot air circulation type, and it is not easy to control nitrogen consumption in such Lyra Reflow Oven furnaces. There are several ways to reduce nitrogen consumption and reduce the opening area of the furnace inlet and outlet. It is very important to use partitions, roller blinds or similar devices to block the unused part of the inlet and outlet space. The method is to use the principle that the hot nitrogen layer is lighter than air and not easy to mix. When designing the Lyra Reflow Oven furnace, the heating chamber is higher than the inlet and outlet, so that a natural nitrogen layer is formed in the heating chamber, reducing the amount of nitrogen compensation and Maintain at the required degree.
