What is nitrogen reflow soldering and what is its function?

With the higher and higher requirements of product process and quality, the quality of reflow soldering has also been greatly improved. Nitrogen filled reflow soldering, referred to as nitrogen reflow soldering, can greatly improve the quality and finished product effect of reflow soldering. Nitrogen reflow soldering is mainly used in precision electronic products such as aerospace, automobile and medical treatment, and has very high requirements for quality, reliability and stability.

Principle of nitrogen reflow welding

Nitrogen reflow welding is mainly to fill the reflow furnace with nitrogen to block the contact between the air in the reflow furnace and the elements as much as possible, so that the oxygen content in the furnace is very small. In this way, the contact between the elements and oxygen can be avoided during welding, which greatly enhances the quality of welding.

Advantages of nitrogen reflow welding

1) Reduce welding oxidation of components, improve welding wetting force, and reduce poor welding quality such as tin ball, bridge and monument;

2) Greatly reduce the void rate of welding and enhance the reliability of products;

Disadvantages of nitrogen reflow welding

1) The cost of nitrogen reflow soldering is higher and higher than that of ordinary reflow soldering;

2) Nitrogen reflow welding has higher requirements and more complex maintenance;

Nitrogen reflow welding has both advantages and disadvantages. If the manufacturer wants to introduce nitrogen reflow welding, it needs to be determined according to its own products. If the customer specifies nitrogen reflow welding, or the product must use nitrogen reflow welding to ensure the welding quality, then nitrogen reflow welding must be applied. Because the customer is the parents of food and clothing. At present, nitrogen reflow welding is relatively mature, especially REHM reflow welding.
