Advantages of reflow soldering and precautions for maintenance

What are the advantages of reflow soldering process technology?

(1) When reflow soldering technology is used for soldering, it is not necessary to immerse the printed circuit board in the molten solder, but to complete the soldering task by means of local heating; Overheating causes damage to components.

(2) Since the welding technology only needs to apply solder on the welding part and complete the welding by local heating, welding defects such as bridging are avoided.

(3) In the reflow soldering process, the solder is only used once, and there is no reuse, so the solder is very clean and free of impurities, which ensures the quality of the solder joints.

Precautions for reflow soldering maintenance

In order to avoid improper cleaning of the furnace, which may cause combustion or explosion, it is strictly forbidden to use highly volatile solvents to clean the inside and outside of the furnace. If it is impossible to avoid using highly volatile solvents such as alcohol, isopropanol, etc., please ensure that such substances evaporate before cleaning. Equipment available. Before maintenance, the welding flux, dust, dirt or other foreign matter on each component must be cleaned and oiled! Special attention is that while we are performing daily maintenance on reflow soldering, if we find that the machine is malfunctioning, we cannot repair it without authorization, and we must notify the equipment management personnel in time to deal with it. At the same time, you must pay attention to safe operation during the maintenance process, and do not operate irregularly.
